High Energy seminar: "Black hole Love story"
Ram Brustein (Ben-Gurion University)
The response of a gravitating object to an external tidal field is encoded in its Love numbers, which identically vanish for classical black holes in 4 spacetime dimensions. I will explain why for quantum…
Thesis Defense: "DEVELOPMENT OF MUSTANG-2: A MICROWAVE SQUID MULTIPLEXED TES ARRAY FOR 90 GHZ IMAGING"
Sara Stanchfield (University of Pennsylvania)
Galaxy clusters provide rich astrophysical laboratories with which to study some of the most energy event since the Big Bang. The myriad of important astrophysical phenomena that are present in these high energy…
Condensed and Living Matter Seminar: "Semiconductor moiré materials: a new platform for strong correlation and topology"
Jie Shan (Cornell University)
When two van der Waals materials of slightly different orientations or lattice constants are overlaid, a long-wavelength moiré pattern emerges. In semiconductors or semimetals, the low-energy physics can…
Astrophysics seminar: "Characterizing Distant Worlds: Atmospheric Observations of Exoplanets with Hubble & JWST"
Munazza Alam (Carnegie Earth & Planets Laboratory)
In the past two decades, we have discovered thousands of planets outside of the Solar System, many of which are nothing like our own. We can learn a great deal about the properties of…
Elon Musk Public Lecture: "Cosmic Inflation: My journey to the edge of science"
Andreas Albrecht (Department of Physics & Astronomy, UC Davis)
In 1982, while a grad student at Penn, my advisor and I wrote a paper that has since become very famous.
Experimental Particle Physics seminar: “EXO-200 recent results and nEXO outlook”
Michelle Dolinski (Drexel University)
The discovery of neutrino mass is direct evidence of physics beyond the Standard Model. It is an experimentally open question whether neutrinos have Majorana masses, and neutrinoless…
Thesis Defense: "Criticality in Eternal Inflation and Superfluidity"
Guram Kartvelishvili (University of Pennsylvania)
Condensed and Living Matter Seminar: "Magnetooptical properties of superconducting Nb thin films in the terahertz region"
Jae Hoon Kim (Yonsei University)
We studied the pair breaking effect of an external magnetic field up to 7 T on the type-II superconductor niobium (Nb) using terahertz time-domain spectroscopy at 1.5 K. Our measurement technique can…
CAMIPM seminar: "Non- and minimally- invasive Diffuse Optical Monitoring of Central Nervous System Hemodynamics"
David R. Busch, Ph.D. Department of Biomedical Engineering, University of Texas Southwestern)
Thesis Defense: "Optical Imaging of Tissue Physiology with Exogenous Contrast Agents"
Sanghoon (Bryan) Chong (University of Pennsylvania)
