Entanglement viscosity to entropy density ratio for spin-3/2 theory
R. V. Khakimov, G. Yu. Prokhorov, O. V. Teryaev
It is known that the Minkowski vacuum appears as a thermal medium to an accelerated observer due to the renowned Unruh effect. More recently, it has been shown that at least for lo…
Weyl anomaly induced transport in hydrodynamics
Shi-Zheng Yang, Jian-Hua Gao, Zuo-Tang Liang +4
We show that the Weyl (trace) anomaly gives rise to a new non-dissipative vector current in accelerated relativistic fluids. The anomaly uniquely fixes the second-order transport c…
Causality, the Kovtun-Son-Starinets bound, and a novel sum rule for spectral densities
G. Yu. Prokhorov, O. V. Teryaev
We directly show that the local ratio of the shear viscosity to the entropy density for Unruh radiation at a finite distance from the horizon is universal and satisfies the relatio…
Entanglement Viscosity: from Unitarity to Irreversibility in Accelerated Frames
G. Yu. Prokhorov
We demonstrate that the unitarity of quantum field theory, through the positivity of spectral functions, underlies thermodynamic irreversibility for a subsystem separated by a hori…
Modeling of acceleration in heavy-ion collisions: occurrence of temperature below the Unruh temperature
G. Yu. Prokhorov, D. A. Shohonov, O. V. Teryaev +2
It has recently been shown that extremely strong electric fields can be created in central collisions of heavy ions, due to which the Schwinger effect can be significant. A direct…
Viscosity, entanglement and acceleration
Dmitry D. Lapygin, Georgy Yu. Prokhorov, Oleg V. Teryaev +1
The Minkowski vacuum in an accelerated frame behaves like a fluid that has not only a finite temperature due to the Unruh effect, but also a finite shear viscosity. Moreover, the r…
