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…

Thermalization in open many-body systems and KMS detailed balance
Matteo Scandi, Álvaro M. Alhambra
Starting from a microscopic description of weak system-bath interactions, we derive from first principles a quantum master equation that does not rely on the well-known rotating wa…
