Static features from mixing in short- and long-range Lindbladians: Markov property and correlations
Paul Rosa-Ruiz, Matteo Scandi, Ángela Capel +1
The classification of mixed-state phases requires criteria beyond two-point correlation functions, such as the decay of the mutual information (MI) and the conditional mutual infor…
A Berry-Esseen Bound for Quantum Lattice Systems
Marcus Cramer, Fernando G. S. L. Brandão, Mădălin Guţă +2
It is expected that the statistical fluctuations of local observables in large quantum systems obey the central limit theorem, and approximate a normal distribution as their size g…
Polynomial-time thermalization and Gibbs sampling from system-bath couplings
Samuel Slezak, Matteo Scandi, Álvaro M. Alhambra +2
Many physical phenomena, including thermalization in open quantum systems and quantum Gibbs sampling, are modeled by Lindbladians approximating a system weakly coupled to a bath. U…
Uniform matrix product states with a boundary
Marta Florido-Llinàs, Álvaro M. Alhambra, David Pérez-García +1
Canonical forms are central to the analytical understanding of tensor network states, underpinning key results such as the complete classification of one-dimensional symmetry-prote…
Stability of thermal equilibrium in long-range quantum systems
Tim Möbus, Jorge Sánchez-Segovia, Álvaro M. Alhambra +1
Experimental realizations of spin models are irremediably prone to errors, which can propagate through the system corrupting experimental signals. We study how such errors affect t…
High-temperature partition functions and classical simulatability of long-range quantum systems
Jorge Sánchez-Segovia, Jan T. Schneider, Álvaro M. Alhambra
Long-range quantum systems, in which the interactions decay as , are of increasing interest due to the variety of experimental set-ups in which they naturally appear. Motiva…
Relaxation of non-integrable systems and correlation functions
Jonathon Riddell, Luis Pedro García-Pintos, Álvaro M. Alhambra
We investigate early-time equilibration rates of observables in closed many-body quantum systems and compare them to those of two correlation functions, first introduced by Kubo an…
