Free fermion entanglement with a semitransparent interface: the effect of graybody factors on entanglement islands
Jorrit Kruthoff, Raghu Mahajan, Chitraang Murdia
We study the entanglement entropy of free fermions in 2d in the presence of a partially transmitting interface that splits Minkowski space into two half-spaces. We focus on the cas…
The double cone geometry is stable to brane nucleation
Raghu Mahajan, Donald Marolf, Jorge E. Santos
In gauge/gravity duality, the bulk double cone geometry has been argued to account for a key feature of the spectral form factor known as the ramp. This feature is deeply associate…
Comments on the Quantum Field Theory of the Coulomb Gas Formalism
Daniel Kapec, Raghu Mahajan
The holomorphic Coulomb gas formalism is a set of rules for computing minimal model observables using free field techniques. We attempt to derive and clarify these rules using stan…
Density matrices in quantum gravity
Tarek Anous, Jorrit Kruthoff, Raghu Mahajan
We study density matrices in quantum gravity, focusing on topology change. We argue that the inclusion of bra-ket wormholes in the gravity path integral is not a free choice, but i…
Matrix ensembles with global symmetries and 't Hooft anomalies from 2d gauge theory
Daniel Kapec, Raghu Mahajan, Douglas Stanford
The Hilbert space of a quantum system with internal global symmetry decomposes into sectors labelled by irreducible representations of . If the system is chaotic, the energi…
Entanglement islands in higher dimensions
Ahmed Almheiri, Raghu Mahajan, Jorge E. Santos
It has been suggested in recent work that the Page curve of Hawking radiation can be recovered using computations in semi-classical gravity provided one allows for "islands" in the…
