Lecture

Physics Colloquium - "Exotic Phases in Moire Systems" Presented by Professor Bogdan Andrei Bernevig, Princeton University

Location:

Lewis Lab 316

February 29, 2024, 4:25 - 5:25pm

I will review the experimental discoveries and amazing puzzles in Twisted Bilayer Graphene and in twisted MoTe2 which culminated with the discovery of long-thought phases of matter such as the Fractional Chern Insulator. We will then show that, theoretically, most of the puzzling…

Lecture

Physics Colloquium - "The Entropy of Hawking Radiation" Presented by Dr. Maldacena - IAS, Princeton

Location:

Lewis Lab 316

February 22, 2024, 4:25 - 5:55pm

We will discuss recent progress on the computation of black hole entropy and the entropy of Hawking radiation. This involves an area formula that computes the fine grained or von Neumann entropy of black hole. The result is consistent with unitarity.

Lecture

Physics Colloquium - "Inquiring Through Black Holes" Presented by Dr. Luis Lehner, Perimeter Institute

Location:

Lewis Lab 316

February 15, 2024, 4:25 - 5:25pm

Black holes have become unique tools in the understanding of a plethora of phenomena in vastly different fronts. From understanding spectacularly energetic events in our universe, gaining insights on potential new particles to unraveling seemingly unrelated phenomena through a firm…

Lecture

Physics Colloquium - "Collective Functionalities Emerging in Microbial Active Matter" Presented by Dr. Mathijssen, University of Pennsylvania

Location:

Lewis Lab 316

February 8, 2024, 4:25 - 5:55pm

 Microbes often cooperate to withstand predators and compete even with multicellular organisms. Together, they can achieve functionalities that alone they cannot. However, this puzzle of how biological self-organization emerges from the collective dynamics of individual…

Seminar

Physics Colloquium - "Solving the Mott Problem" Presented by Professor Philip Phillips, UIUC

Location:

Lewis Lab 316

February 1, 2024, 4:25 - 5:25pm

Superconductivity in the copper-oxide ceramics remains a grand challenge in theoretical physics because of the paucity of tools to treat strongly coupled systems.  In such systems, all intuition based on single-particle physics fails.  Precisely what the propagating degrees…

Lecture

Physics Colloquium - "The Persistence of Spin Coherence in a Crystalline Environment" By Professor Ivan Biaggio

Location:

Lewis Lab 316

January 25, 2024, 4:25 - 5:25pm

The colloquium will focus on the entanglement of triplet exciton pairs as it can be observed in some organic molecular crystals. In such crystals, triplet excitons (quasiparticles with a spin of one) can be created as a spin-entangled pair via fission of a photoinduced singlet exciton…
