Subdiffusion and Many-Body Quantum Chaos with Kinetic Constraints. [PDF]

open access: yesPhysical Review Letters, 2021
We investigate the spectral and transport properties of many-body quantum systems with conserved charges and kinetic constraints. Using random unitary circuits, we compute ensemble-averaged spectral form factors and linear-response correlation functions,

Adiabatic Eigenstate Deformations as a Sensitive Probe for Quantum Chaos [PDF]

open access: yesPhysical Review X, 2020
In the past decades, it was recognized that quantum chaos, which is essential for the emergence of statistical mechanics and thermodynamics, manifests itself in the effective description of the eigenstates of chaotic Hamiltonians through random matrix ...

Quantum-classical mechanics as an alternative to quantum mechanics in molecular and chemical physics

open access: yesHeliyon, 2019
In quantum mechanics, the theory of quantum transitions is grounded on the convergence of a series of time-dependent perturbation theory. In nuclear and atomic physics, this series converges because the dynamics of quantum transitions (quantum jumps) are

Chaos in coupled Kerr-nonlinear parametric oscillators

open access: yesPhysical Review Research, 2021
A Kerr-nonlinear parametric oscillator (KPO) can generate a quantum superposition of two oscillating states, known as a Schrödinger cat state, via quantum adiabatic evolution and can be used as a qubit for gate-based quantum computing and quantum ...

Chaos in a double driven dissipative nonlinear oscillator [PDF]

open access: yes, 2001
We propose an anharmonic oscillator driven by two periodic forces of different frequencies as a new time-dependent model for investigating quantum dissipative chaos.

Recent Developments in the Holographic Description of Quantum Chaos

open access: yesAdvances in High Energy Physics, 2019
We review recent developments encompassing the description of quantum chaos in holography. We discuss the characterization of quantum chaos based on the late time vanishing of out-of-time-order correlators and explain how this is realized in the dual ...

Chaos and high temperature pure state thermalization

open access: yesJournal of High Energy Physics, 2019
Classical arguments for thermalization of isolated systems do not apply in a straightforward way to the quantum case. Recently, there has been interest in diagnostics of quantum chaos in many-body systems.

Quantum chaos and quantum algorithms [PDF]

open access: yesPhysical Review A, 2002
It was recently shown (quant-ph/9909074) that parasitic random interactions between the qubits in a quantum computer can induce quantum chaos and put into question the operability of a quantum computer. In this work I investigate whether already the interactions between the qubits introduced with the intention to operate the quantum computer may lead ...

Quantum coherence as a signature of chaos

open access: yesPhysical 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.
