Extended eigenstate thermalization and the role of FZZT branes in the Schwarzian theory

recommendations! Published in 2020 at "Journal of High Energy Physics"

DOI: 10.1007/jhep03(2020)168

Abstract: In this paper we provide a universal description of the behavior of the basic operators of the Schwarzian theory in pure states. When the pure states are energy eigenstates, expectation values of non-extensive operators are… read more here.

DOI: 10.1103/physrevb.96.115140

Abstract: We use exact diagonalization to study the eigenstate thermalization hypothesis (ETH) in the quantum dimer model on the square and triangular lattices. Due to the nonergodicity of the local plaquette-ip dynamics, the Hilbert space, which… read more here.

DOI: 10.1103/physreve.99.042139

Abstract: The eigenstate thermalization hypothesis (ETH) implies a form for the matrix elements of local operators between eigenstates of the Hamiltonian, expected to be valid for chaotic systems. Another signal of chaos is a positive Lyapunov… read more here.

DOI: 10.1103/physrevlett.120.230601

Abstract: We consider the set of all initial states within a microcanonical energy shell of an isolated many-body quantum system, which exhibit an arbitrary but fixed nonequilibrium expectation value for some given observable A. On the… read more here.

DOI: 10.1103/physrevlett.123.111602

Abstract: Infinite-dimensional conformal symmetry in two dimensions leads to integrability of 2D conformal field theories (CFTs) by giving rise to an infinite tower of local conserved quantum Korteweg-de Vries (qKdV) charges in involution. We discuss how… read more here.

DOI: 10.1103/physrevlett.123.260601

Abstract: Generic rotationally invariant matrix models satisfy a simple relation: the probability distribution of half the difference between any two diagonal elements and the one of off-diagonal elements are the same. In the spirit of the… read more here.

DOI: 10.1103/physrevlett.125.070605

Abstract: Eigenstate thermalization is widely accepted as the mechanism behind thermalization in generic isolated quantum systems. Using the example of a single magnetic defect embedded in the integrable spin-1/2 XXZ chain, we show that locally perturbing… read more here.

DOI: 10.1103/physrevlett.129.170603

Abstract: Quantum thermalization is well understood via the eigenstate thermalization hypothesis (ETH). The general form of ETH, describing all the relevant correlations of matrix elements, may be derived on the basis of a "typicality" argument of… read more here.

DOI: 10.1103/physrevlett.130.140402

Abstract: The eigenstate thermalization hypothesis (ETH) explains why nonintegrable quantum many-body systems thermalize internally if the Hamiltonian lacks symmetries. If the Hamiltonian conserves one quantity ("charge"), the ETH implies thermalization within a charge sector-in a microcanonical… read more here.
