Exceptional dynamical quantum phase transitions in periodically driven systems
Nature Communications, 2021 Understanding phase transitions in systems out of equilibrium is a topic of high interest. Here the author discusses the spontaneous antiunitary symmetry breaking leading to exceptional dynamical quantum phase transitions in driven many-body systems.

Statistical mechanics for non-Hermitian quantum systems
Physical Review Research, 2023 We present a systematic study of statistical mechanics for non-Hermitian quantum systems. Our work reveals that the stability of a non-Hermitian system necessitates the existence of a single path-dependent conserved quantity, which, in conjunction with ...

Hybrid classical-quantum computing: Applications to statistical mechanics of financial markets [PDF]
E3S Web of Conferences, 2021 Hybrid Classical-Quantum computing is now offered by several commercial quantum computers. In this project, a model of financial options, Statistical Mechanics of Financial Markets (SMFM), uses this approach. However, only Classical (super-)computers are

Relaxation of Multitime Statistics in Quantum Systems [PDF]
Quantum, 2023 Equilibrium statistical mechanics provides powerful tools to understand physics at the macroscale. Yet, the question remains how this can be justified based on a microscopic quantum description. Here, we extend the ideas of pure state quantum statistical

Contextuality in Classical Physics and Its Impact on the Foundations of Quantum Mechanics
Entropy, 2021 It is shown that the hallmark quantum phenomenon of contextuality is present in classical statistical mechanics (CSM). It is first shown that the occurrence of contextuality is equivalent to there being observables that can differentiate between pure and

Solving quantum statistical mechanics with variational autoregressive networks and quantum circuits [PDF]
Machine Learning: Science and Technology, 2019 We extend the ability of an unitary quantum circuit by interfacing it with a classical autoregressive neural network. The combined model parametrizes a variational density matrix as a classical mixture of quantum pure states, where the autoregressive ...

Statistical mechanics of quantum error correcting codes [PDF]
Physical review B, 2020 We study stabilizer quantum error-correcting codes (QECC) generated under hybrid dynamics of local Clifford unitaries and local Pauli measurements in one dimension.
