Not all black holes decohere quantum superpositions
Anna Biggs, Stefano Trezzi
We study the decoherence induced by near-extremal charged black holes on quantum systems in their exterior. Specifically, we analyze a thought experiment recently discussed in the…
A melonic quantum mechanical model without disorder
Anna Biggs, Loki L. Lin, Juan Maldacena
We consider a quantum mechanical model involving interacting fermions without disorder that has the same low energy physics as the supersymmetric SYK model. The model is in…
Higher-point correlators in the BFSS matrix model
Anna Biggs, Aidan Herderschee
We investigate higher-point correlators in the BFSS matrix model, a non-conformal theory dual to type IIA string theory, using Witten diagrams and techniques from the amplitudes pr…
Following the state of an evaporating charged black hole into the quantum gravity regime
Anna Biggs
We study the energy probability density function of an evaporating near-extremal charged black hole. At sufficiently low energies, such black holes experience large quantum metric…
A supersymmetric SYK model with a curious low energy behavior
Anna Biggs, Juan Maldacena, Vladimir Narovlansky
We consider = 2, 4 supersymmetric SYK models that have a peculiar low energy behavior, with the entropy going like , where $a \neq…
Scaling similarities and quasinormal modes of D0 black hole solutions
Anna Biggs, Juan Maldacena
We study the gravity solution dual to the D0 brane quantum mechanics, or BFSS matrix model, in the 't Hooft limit. The classical physics described by this gravity solution is invar…
