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.
Physics Colloquium - "Inquiring Through Black Holes" Presented by Dr. Luis Lehner, Perimeter Institute
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…
Physics Colloquium - "Collective Functionalities Emerging in Microbial Active Matter" Presented by Dr. Mathijssen, University of Pennsylvania
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…
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…
Physics Colloquium - "The Persistence of Spin Coherence in a Crystalline Environment" By Professor Ivan Biaggio
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…
