15a, 15b, 15c lab req

by Morin, David

This email is a reminder about the Physics Department's rule for the 15b and 15c labs, and also (starting with the class of 2027) the 15a lab; see below. The lab rule applies to Physics concentrators, Chem/Phys concentrators, and students completing a Physics secondary: If you skip 15b and/or 15c and satisfy the E&M and/or waves requirement by taking an alternative course (approved by Prof. Georgi or me), then you must still complete the 15b and/or 15c labs at some point, on a pass/fail basis. (However, you don't need to do the 15b lab if you took AP50b or PS12b.) This is just an internal Physics Dept requirement; it’s doesn’t shown up anywhere in my.harvard. You can complete the labs in a future semester if you wish, but our recommendation is that you do them at the same time you take the alternative course. (Students in 15b and 15c must of course do the lab when taking the course.) However, if you’re a senior, we strongly recommend doing the lab **now in the fall**, because the labs get very crowded in the spring, and additionally you may be traveling around visiting grad schools etc. NEW THIS YEAR: Starting with the incoming first-years (the class of 2027), we will also require the 15a lab, for students who don’t take 15a/16/19 (or AP50a or PS12a). If you are presently a sophomore or higher, this does NOT apply to you. You don’t need to compete the 15a lab if you didn’t take 15a/16. You just need to do the 15b and 15c labs. To schedule your lab time, please email (as soon as possible): 15a: Preceptor Gregorio Ponti (gponti(a)g.harvard.edu<mailto:gponti@g.harvard.edu>) 15b: Prof. Mara Prentiss (prentiss(a)g.harvard.edu<mailto:prentiss@g.harvard.edu>) 15c: Preceptor Anna Wang-Holtzen (annawang1(a)g.harvard.edu<mailto:annawang1@g.harvard.edu>) Please let me know if you have any questions.

SAVE THE DATE - November 13, 14, 15 - Jean Dalibard - Loeb Lectures in Physics

by Davis, Jolanta M.

2023 Morris Loeb Lectures in Physics Jean Dalibard Professor Collège de France [cid:e26b916b-bbca-4f2b-9b59-b123e69d6efe] all lectures will be held in Jefferson 250 (17 Oxford Street, Cambridge, MA) and streamed live through zoom (please see the link below) Monday, November 13, 4:30pm Colloquium Tea will be served in Jefferson 450 at 3:30pm "Scale invariance, a hidden symmetry explored with quantum gases" Scale invariance, a concept initially introduced in high-energy physics, has gained numerous applications in the physics of quantum fluid. It is applicable to strongly interacting Fermi gases, two-dimensional Bose gases, as well as few-body systems that exhibit the "Efimov effect." In the presentation, I will illustrate how scale and conformal invariance emerge in cold atomic gases. I will use various examples ranging from thermodynamics to soliton physics to specific structures with periodic time evolution called "breathers". Tuesday, November 14, 4:30pm "Surprises in soliton physics with quantum gas mixtures" Solitons are nonlinear wave packets that maintain their shape during free propagation. In quantum gases, bright and dark solitons are observed for attractive and repulsive interactions, exhibiting relatively simple behavior. However, mixtures of gases result in a much more complex physics, with the emergence of dark-bright and magnetic solitons. Here, we examine some non-intuitive phenomena in this context, including the following experimental observation: a magnetic soliton exposed to a constant force undergoes periodic motion, similar to the Bloch oscillation of an electron in a perfect crystal, despite lacking an underlying periodic potential in this setup. Wednesday, November 15, 4:30pm "Is a zero-temperature Bose-Einstein condensate fully superfluid?" At zero temperature, a Galilean-invariant Bose fluid is anticipated to be completely superfluid. When translational (and thus Galilean) invariance is broken, A.J. Leggett demonstrated in the 1970s that the superfluid fraction must be strictly less than one. Here, we examine both theoretically and experimentally how the presence of an external 1D periodic potential quenches the superfluid fraction of a dilute Bose-Einstein condensate and compare it to Leggett's bound. We show that the anisotropy of sound velocity provides a reliable determination of the superfluid fraction and explore the potential application of these principles to other quantum fluids. # # # Jean Dalibard is a professor at the Collège de France and leads a research team at the Laboratoire Kastler Brossel in Paris. His research in atomic physics and quantum optics covers both experimental and theoretical aspects. In the 1980s, together with Claude Cohen-Tannoudji, he studied the mechanisms at play in laser cooling of atoms, in particular the "Sisyphus effect". The modelling of these phenomena led him - along with other authors - to propose the method of "quantum trajectories". Since the discovery of gaseous Bose-Einstein condensates in 1995, he has been interested in many aspects of this quantum matter, as well as the links that exist between these fluids and other condensed matter systems. He was elected a foreign member of the National Academy of Sciences in 2021. # # # The lectures are sponsored by the Morris Loeb Lectureship Fund. # # # Zoom webinar 2023 Loeb Lectures - Jean Dalibard Nov 13, 2023 04:30 PM Nov 14, 2023 04:30 PM Nov 15, 2023 04:30 PM Please click the link below to join the webinar: https://harvard.zoom.us/j/92075949163?pwd=ZExlODlHbS82WkdWREJZSnU5WWpiUT09 Passcode: 438483 Or One tap mobile : +19294362866,,92075949163#,,,,*438483# US (New York) +13017158592,,92075949163#,,,,*438483# US (Washington DC) Or Telephone: Dial(for higher quality, dial a number based on your current location): +1 929 436 2866 US (New York) +1 301 715 8592 US (Washington DC) +1 305 224 1968 US +1 309 205 3325 US +1 312 626 6799 US (Chicago) +1 646 931 3860 US +1 253 205 0468 US +1 253 215 8782 US (Tacoma) +1 346 248 7799 US (Houston) +1 360 209 5623 US +1 386 347 5053 US +1 507 473 4847 US +1 564 217 2000 US +1 669 444 9171 US +1 669 900 6833 US (San Jose) +1 689 278 1000 US +1 719 359 4580 US Webinar ID: 920 7594 9163 Passcode: 438483 International numbers available: https://harvard.zoom.us/u/ayM8vUgwc Or an H.323/SIP room system: H.323: 162.255.37.11 (US West) 162.255.36.11 (US East) 115.114.131.7 (India Mumbai) 115.114.115.7 (India Hyderabad) 213.19.144.110 (Amsterdam Netherlands) 213.244.140.110 (Germany) 103.122.166.55 (Australia Sydney) 103.122.167.55 (Australia Melbourne) 149.137.40.110 (Singapore) 64.211.144.160 (Brazil) 69.174.57.160 (Canada Toronto) 65.39.152.160 (Canada Vancouver) 207.226.132.110 (Japan Tokyo) 149.137.24.110 (Japan Osaka) Meeting ID: 920 7594 9163 Passcode: 438483 SIP: 92075949163(a)zoomcrc.com Passcode: 438483 With any questions, please contact: _________ Jolanta M.

Pumpkin Drop on Tuesday 10/31 at 4 pm!

by Emma Weller

Hello everyone, Please join us on Halloween (Tuesday 10/31) for the annual physics department pumpkin drop! Pie and cider will be served in the Physics Library at 4 pm, and the pumpkins will be dropped at 4:30. This is an annual Society of Physics Students (SPS) classic: “The undergraduate SPS runs a pumpkin drop every year to celebrate the coming of fall and test that the laws of gravity still hold in this academic year. We vent our frustrations in the enthusiastic destruction of produce, and we indulge our curiosity by varying the temperature or internal composition of that doomed produce. If Newton had been born in the New World, a falling pumpkin would have inspired him. But even if we don't inspire the next Newton, we do have a smashing good time.” Hope to see you there!

STARTING SOON - Harvard Physics Colloquium – October 30, 4:30 PM – Peter Maurer, University of Chicago

by Hagerty, Shannon

Harvard Physics Colloquium Monday, October 30, 2023    Lecture in Jefferson 250 @ 4:30 PM  Tea served in Jefferson 450 @ 3:30 PM ***** Peter Maurer, Assistant Professor of Molecular Engineering, University of Chicago INTERFACING BIOMOLECULES WITH COHERENT QUANTUM SENSORS Quantum metrology enables some of the world's most sensitive measurements with potentially far reaching applications in the life sciences. Although the ultrahigh sensitivity of qubit sensors has spurred the imagination of researchers, implementation in actual devices that enable monitoring cellular processes or detecting diseases still remains largely elusive. Overcoming limitations that hold back wider application of quantum technology in the life sciences, requires advances in both fundamental science and engineering. In this talk, I will discuss our research group's recent results on addressing one of these long-standing research challenges, namely how to interface highly coherent quantum sensors with biological target systems. My discussion will start with the development of a novel biocompatible surface functionalization architecture for highly coherent diamond crystals. I will then continue with discussing a new approach to engineering spin coherence in core-shell structured diamond particles, which can be readily chemically modified and delivered to intact biological systems. Finally, I will conclude my talk with an outlook on a novel class of molecular qubit sensors that will overcome many of the fundamental challenges associated with current diamond based quantum sensors. The unifying theme of these advances are the convergence of techniques from single-molecule biophysics, material science, and quantum engineering. Specific applications of the developed sensing platforms to questions in the life sciences will be discussed throughout this talk. Peter Maurer is an Assistant Professor at the University of Chicago. Peter received his PhD from Harvard, where he worked with Misha Lukin on NV centers in diamond. One of the projects that Peter was leading as a graduate student, was the development of a diamond nano-thermometer that enabled measurements of temperature profiles in living cells. The idea of utilizing quantum sensors to probe and manipulate biological systems has motivated Peter to complete his postdoctoral training with Steven Chu at Stanford, where he developed luminescent nano-probes for electron microscopy. Now at the University of Chicago Peter is combining the quantum engineering, biophysics, and material engineering tools that he learned during his PhD and postdoctoral training to develop biocompatible quantum sensing tools and apply them to real world problems in the life sciences.
