A bstract We study the real time formation of ground state two coupled SYK models. This is a highly entangled which close to thermofield double and can be viewed as wormhole. start from high temperature state, we let it cool by coupling cold bath. numerically solve for large N dynamics. Our main result that system forms wormhole going through region with negative specific heat, taking independe...

In this paper, the differential cross section for Compton scattering process is calculated. Two types of corrections are investigated: due to violation Lorentz symmetry and thermal effects. An extended QED considered introduce parameter that leads breaking symmetry. While temperature effects introduced using Thermofield Dynamics formalism. It shown changes with both corrections. These dominant ...

A bstract In this work, we study a generalization of the coupled Sachdev-Ye-Kitaev (SYK) model with U(1) charge conservations. The contains two copies complex SYK at different chemical potentials, by direct hopping term. zero-temperature and small coupling limit averaged potential, ground state is an eternal wormhole connecting sides, specific Q = 0, which equivalent to thermofield double state...

Entanglement renormalization is a method for coarse-graining quantum state in real space, with the multi-scale entanglement ansatz (MERA) as notable example. We obtain an scheme finite-temperature (Gibbs) states by applying MERA to their canonical purification, thermofield double state. As example, we find analytically exact circuit finite temperature two-dimensional toric code which maps it co...

We establish a systematic framework for studying quantum computational complexity of Gaussian states charged systems based on Nielsen's geometric approach. use this to examine the effect chemical potential dynamics complexity. As an example, we consider thermofield double state constructed from two free massive complex scalar fields in presence potential. show that factorizes between positively...

The thermofield dynamics of the D = 10 heterotic thermal string theory is described in proper reference to the thermal duality symmetry as well as the thermal stability of modular invariance in association with the global phase structure of the D = 10 heterotic thermal string ensemble. Building up thermal string theories based upon the thermofield dynamics (TFD) [1] has gradually been endeavour...

A quark-antiquark effective model is studied in a toroidal topology at finite temperature. The described by Schr\"odinger equation with linear potential which embedded torus. following aspects are analysed: (i) the nonclassicality structure using Wigner function formalism; (ii) temperature and size-effects generalization of Thermofield Dynamics written phase space; (iii) order to include spin q...
