Modular invariance and thermal effective field theory in CFT

open access: yesJournal of High Energy Physics
We use thermal effective field theory to derive that the coefficient of the first subleading piece of the thermal free energy, c 1, is equal to the coefficient of the subleading piece of the Casimir energy on S 1 × S d−2 for d ≥ 4.

Spectral form factor of a quantum spin glass

open access: yesJournal of High Energy Physics, 2022
It is widely expected that systems which fully thermalize are chaotic in the sense of exhibiting random-matrix statistics of their energy level spacings, whereas integrable systems exhibit Poissonian statistics.

THERMAL FIELD THEORY IN NON-EQUILIBRIUM STATES [PDF]

open access: yesInternational Journal of Modern Physics B, 1996
Conventional transport theory is not really applicable to nonequilibrium systems which exhibit strong quantum effects. We present two different approaches to overcome this problem. Firstly we point out how transport equations may be derived that incorporate a nontrivial spectral function as a typical quantum effect, and test this approach in a toy ...

Real-time spin systems from lattice field theory

open access: yesJournal of High Energy Physics, 2023
We construct a lattice field theory method for computing the real-time dynamics of spin systems in a thermal bath. This is done by building on previous work of Takano with Schwinger-Keldysh and functional differentiation techniques. We derive a Schwinger-

Thermalization and chaos in a 1+1d QFT

open access: yesJournal of High Energy Physics, 2023
We study aspects of chaos and thermodynamics at strong coupling in a scalar model using LCT numerical methods. We find that our eigenstate spectrum satisfies Wigner-Dyson statistics and that the coefficients describing eigenstates in our basis satisfy ...

Equilibrium States in Thermal Field Theory and in Algebraic Quantum Field Theory [PDF]

open access: yesAnnales Henri Poincaré, 2019
In this paper we compare the construction of equilibrium states at finite temperature for self-interacting massive scalar quantum field theories on Minkowski spacetime proposed by Fredenhagen and Lindner with results obtained in ordinary thermal field theory, by means of real time and Matsubara formalisms. In the construction of this state, even if the

Universality of quantum information in chaotic CFTs

open access: yesJournal of High Energy Physics, 2018
We study the Eigenstate Thermalization Hypothesis (ETH) in chaotic conformal field theories (CFTs) of arbitrary dimensions. Assuming local ETH, we compute the reduced density matrix of a ball-shaped subsystem of finite size in the infinite volume limit ...
