Isospectral Twirling and Quantum Chaos [PDF]
Entropy, 2021 We show that the most important measures of quantum chaos, such as frame potentials, scrambling, Loschmidt echo and out-of-time-order correlators (OTOCs), can be described by the unified framework of the isospectral twirling, namely the Haar average of a

Quantum Chaos in the Dynamics of Molecules [PDF]
Entropy, 2022 Quantum chaos is reviewed from the viewpoint of “what is molecule?”, particularly placing emphasis on their dynamics. Molecules are composed of heavy nuclei and light electrons, and thereby the very basic molecular theory due to Born and Oppenheimer ...

Quantum Chaos is Quantum [PDF]
Quantum, 2021 It is well known that a quantum circuit on $N$ qubits composed of Clifford gates with the addition of $k$ non Clifford gates can be simulated on a classical computer by an algorithm scaling as $\text{poly}(N)\exp(k)$\cite{bravyi2016improved}.

Quantum Chaos and Quantum Randomness—Paradigms of Entropy Production on the Smallest Scales [PDF]
Entropy, 2019 Quantum chaos is presented as a paradigm of information processing by dynamical systems at the bottom of the range of phase-space scales. Starting with a brief review of classical chaos as entropy flow from micro- to macro-scales, I argue that quantum ...

Quantum Chaos in the Extended Dicke Model. [PDF]
Entropy (Basel), 2022 We systematically study the chaotic signatures in a quantum many-body system consisting of an ensemble of interacting two-level atoms coupled to a single-mode bosonic field, the so-called extended Dicke model.

Quantum coherence as a signature of chaos
Physical Review Research, 2021 We establish a rigorous connection between quantum coherence and quantum chaos by employing coherence measures originating from the resource theory framework as a diagnostic tool for quantum chaos.

Genuine quantum scars in many-body spin systems [PDF]
Nature CommunicationsChaos makes isolated systems of many interacting particles quickly thermalize and forget about their past. Here, we show that quantum mechanics hinders chaos in many-body systems: although the quantum eigenstates are thermal and strongly entangled ...
