Condensed Matter Seminar: "Magnetism in Amorphous Alloys"

Frances Hellman (University of California at Berkeley)
- David Rittenhouse Laboratory, A4

Most condensed matter textbooks start by introducing crystal symmetries and the periodic lattice as foundational to the field.  Yet, it has long been known that the amorphous structure supports ferromagnetism,…



Astro Seminar: "Fundamental Physics from the Non-linear Universe"

Marcel Schmittfull (IAS)
David Rittenhouse Laboratory, A4

The cosmology community is running a large program of galaxy surveys over the next 10 years. Our goal is to map out the properties of dark energy as a function of time, measure the sum of neutrino masses, and study…



High Energy Theory Seminar: "A Toy Model of Axion Gauge Field Inflation"

Robert Caldwell (Dartmouth College)
David Rittenhouse Laboratory, 2N36

We present a toy model of an axion gauge field inflation scenario that yields viable density and gravitational wave spectra. The scenario consists of an axionic inflaton in a steep potential that is effectively…



*Special Condensed Matter Seminar*: "Self-organization and Self-assembly in Bio-molecular Systems"

Prof. Erwin Frey (University of Munich)
David Rittenhouse Laboratory, A2

Active matter is a fascinating new field in soft matter physics aiming to understand how interacting active particles self-organize into an intriguing set of patterns and collective non-equilibrium states.…

Physics Department Colloquium: "Cal-Bridge and CAMPARE/CHAMP: Engaging Underrepresented Students in Physics and Astronomy"

Alex Rudolph (Cal Poly Pomona) hosted by: James Aguirre
- David Rittenhouse Laboratory - A8

The level of participation by underrepresented minority (URM) and female students in physics and astronomy PhD programs is shamefully low (2-4% for URM v. 30% in the general population; 20% for women v. 50% in the…

PHYSICS & ASTRONOMY CAREER SEMINAR: 10 Essential Steps to Successful Job Hunting for Physics PhD Students

Dr. Joseph Barber, Senior Associate Director (Penn Career Services)
David Rittenhouse Laboratory, 3W2

Whether you are applying for faculty positions or for jobs in the broad range of other industries/fields that value a STEM PhD, there is plenty you can and should be doing throughout your PhD to position yourself for…



Condensed Matter Seminar: "The Case for an Exciton Metal in Bilayer Graphene"

Michael Zaletel (Princeton University)
- David Rittenhouse Laboratory, A4

Graphene based heterostructures have emerged as a pristine platform for exploring the interplay of symmetry, topology and non-Abelian excitations in the quantum Hall regime. I will begin with a theoretical review of…
