Quantum Stochastic Walks on the Permutation Group
Feng He, Arthur Hutsalyuk, Giuseppe Mussardo +1
How rapidly does order give way to randomness, and can quantum coherence accelerate this process? We address these questions through the paradigmatic problem of card shuffling, for…
Spectral Decimation of Quantum Many-Body Hamiltonians
Feng He, Arthur Hutsalyuk, Giuseppe Mussardo +1
We develop a systematic theory of spectral decimation for quantum many-body Hamiltonians and show that it provides a quantitative probe of emergent symmetries in statistically mixe…
Statistical Signatures of Integrable and Non-Integrable Quantum Hamiltonians
Feng He, Arthur Hutsalyuk, Giuseppe Mussardo +1
Integrability is a cornerstone of classical mechanics, where it has a precise meaning. Extending this notion to quantum systems, however, remains subtle and unresolved. In particul…
