Universality of quantum information in chaotic CFTs
Journal 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 ...

Thermalization and chaos in a 1+1d QFT
Journal 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 ...

Global symmetries and partial confinement
Journal of High Energy Physics, 2022 In gauge theories, spontaneous breaking of the centre symmetry provides a precise definition of deconfinement. In large-N gauge theories, evidence has emerged recently that between confined and deconfined phases a partially-deconfined phase can appear ...

The thermal behaviour of three different auger pressure grouted piles used as heat exchangers [PDF]
, 2014 Three auger pressure grouted (APG) test piles were constructed at a site in Richmond, Texas. The piles were each equipped with two U-loops of heat transfer pipes so that they could function as pile heat exchangers.

Some information theoretic aspects of de-Sitter holography
Journal of High Energy Physics, 2020 Built on our observation that entangling surfaces of the boundary field theory are great co-dimension one spheres in the context of DS/dS correspondence, we study some information theoretic quantities of the field theory dual intensively using ...

Relativistic fluid dynamics and its extensions as an effective field theory
, 2020 We examine hydrodynamics from the perspective of an effective field theory. The microscopic scale in this case is the thermalization scale, and the macroscopic scale is the gradient, with thermal fluctuations playing the role of (sic). We argue that this

Kubo formulas for thermodynamic transport coefficients
Journal of High Energy Physics, 2018 Uncharged relativistic fluids in 3+1 dimensions have three independent thermodynamic transport coefficients at second order in the derivative expansion. Fluids with a single global U(1) current have nine, out of which seven are parity preserving.

Selected issues in thermal field theory [PDF]
Nuclear Physics A, 2014 New developments on hot and dense QCD in effective field theories are reviewed. Recent investigations in lattice gauge theories for the low-lying Dirac eigenmodes suggest survival hadrons in restored phase of chiral symmetry. We discuss expected properties of those bound states in a medium using chiral approaches.

Thermality of eigenstates in conformal field theories
Physical Review E, 2017 The eigenstate thermalization hypothesis (ETH) provides a way to understand how an isolated quantum mechanical system can be approximated by a thermal density matrix. We find a class of operators in (1+1)-dimensional conformal field theories, consisting of quasiprimaries of the identity module, which satisfy the hypothesis only at the leading order in ...
