Quantum simulation of Hawking radiation and curved spacetime with a superconducting on-chip black hole
Yun-Hao Shi, Run-Qiu Yang, Zhongcheng Xiang +10
Hawking radiation is one of the quantum features of a black hole that can be understood as a quantum tunneling across the event horizon of the black hole, but it is quite difficult…

Entanglement entropy production in deep inelastic scattering
Kun Zhang, Kun Hao, Dmitri Kharzeev +1
Deep inelastic scattering (DIS) samples a part of the wave function of a hadron in the vicinity of the light cone. Lipatov constructed a spin chain which describes the amplitude of…

Dirac systems with magnetic field and position dependent mass: Darboux transformations and equivalence with generalized Dirac oscillators
Axel Schulze-Halberg, Pinaki Roy
We construct a Darboux transformation for a class of two-dimensional Dirac systems at zero energy. Our starting equation features a position-dependent mass, a matrix potential, and…
