Acoustic black holes in curved spacetime and the emergence of analogue Minkowski spacetime

XH Ge, M Nakahara, SJ Sin, Y Tian, SF Wu - Physical Review D, 2019 - APS
Gravity is not only able to be mimicked in flat spacetimes, but also in curved spacetimes. We
study analogue gravity models in curved spacetime by considering the relativistic Gross …

Testing the upper bound on the speed of scrambling with an analogue of Hawking radiation using trapped ions

Z Tian, Y Lin, UR Fischer, J Du - The European Physical Journal C, 2022 - Springer
The Lyapunov exponent of a quantum system has been predicted to be bounded by λ L≤ 2
π T/ħ, where T is its temperature, as established by Maldacena, Shenker, and Stanford …
