Astro Seminar: "Cosmology Large Angular Scale Surveyor (CLASS)"

Zhilei Xu (Johns Hopkins University)
- David Rittenhouse Laboratory, 4C8

Cosmology Large Angular Scale Surveyor (CLASS) is an array of telescopes to observe Cosmic Microwave Background (CMB) in Chile. CLASS will make large angular scale CMB polarization measurements in frequency bands at …



Special Condensed Matter Seminar: "Real-space imaging of a nematic quantum liquid"

Ben Feldman, Princeton University
- David Rittenhouse Laboratory, A4

Electronic phases in condensed matter systems generally respect the symmetries of their solid state host. However, interactions among electrons can give rise to a variety of exotic correlated states characterized by…



Astro Seminar: "Measuring the Polarized Cosmic Microwave Background with POLARBEAR and the Simons Array"

Frederick Matsuda (University of California) hosted by Mark Devlin
David Rittenhouse Laboratory, A8

POLARBEAR is a high resolution polarization sensitive instrument in Chile currently observing the polarized Cosmic Microwave Background (CMB) signal in order to probe the physics of the early universe and inflation.…



Night Skies in the Observatory: "How to find another Earth … Nearby"

Professor James Aguirre (UPenn)
- The Franklin Institute

In the last twenty years, the notion that planets exist outside our solar system has moved from informed speculation to hard, observational science.  James will discuss how we find planets outside the solar system,…



Dissertation Defense: "Nano/Biosensors Based on Large Area Graphene"

Pedro Ducos (UPenn)
Singh Center, Room 035



Experimental Particle Physics: "TBA"

Alessandro Tricoli (Brookhaven National Laboratory)
David Rittenhouse Laboratory, 4C8



High Energy Seminar: "Entanglement, Gravity, and Quantum Error Correction"

Xi Dong (IAS)
David Rittenhouse Laboratory, 2N36

Over the last few years it has become increasingly clear that there is a deep connection between quantum gravity and quantum information. The connection goes back to the discovery that black hole entropy is given by…



"Sounds of Silent: Listening to the Universe with Gravitational Waves”

Prof. Dr. Alessandra Buonanno, Director at Max Planck Institute for Gravitational Physics, Head of the division Astrophysical and Cosmological Relativity
Penn Museum, Widener Lecture Room,
University of Pennsylvania



Department Colloquium: "The New Era of Gravitational-Wave Physics and Astrophysics"

Alessandra Buonanno (MPI Munich) hosted by Justin Khoury
David Rittenhouse Laboratory, A8

The detection by LIGO of gravitational waves emitted by coalescing binary black holes heralded a new era in physics and astrophysics. I will review the theoretical work aimed at solving the two-body problem in…
