High Energy seminar: "TBA"
John T. Giblin, Jr. (Kenyon College)
Astrophysics seminar: "Ultralight sails for interstellar space travel"
Deep Jariwala and Igor Bargatin (University of Pennsylvania)
We argue that light sails with nanometer-scale thicknesses that are rapidly accelerated to relativistic velocities by lasers must be significantly curved in order to reduce their intrafilm mechanical…
Condensed and Living Matter Seminar: "Neuronal biomechanics measured using combined atomic force – traction force microscopy"
Christian Staii (Tufts University)
During brain development neurons grow axons and dendrites that extend from the cell body and connect with other neurons to form neuronal circuits. Axons navigate over long distances (10-100 times…
High Energy seminar: "Precision Physics & Proton Structure at the LHC"
Johannes K. L. Michel (Massachusetts Institute of Technology)
The LHC precision program critically relies on precise theory predictions for Standard-Model baseline rates to identify possible deviations due to New Physics and extract Standard Model…
Primakoff Lecture: “From Nonlinear Optics to High-Intensity Laser Physics”
Donna Strickland (University of Waterloo)
The laser increased the intensity of light that can be generated by orders of magnitude and thus brought about nonlinear optical interactions with matter. Chirped pulse amplification, also known as CPA, changed the…
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.
