Quantum chaos and ensemble inequivalence of quantum long-range Ising chains
Angelo Russomanno, Michele Fava, Markus Heyl
We use large-scale exact diagonalization to study the quantum Ising chain in a transverse field with long-range power-law interactions decaying with exponent . We numerically st…
Subdiffusive dynamics and critical quantum correlations in a disorder-free localized Kitaev honeycomb model out of equilibrium
Guo-Yi Zhu, Markus Heyl
Disorder-free localization has recently emerged as a mechanism for ergodicity breaking in homogeneous lattice gauge theories. In this work we show that this mechanism can lead to u…
Local measures of dynamical quantum phase transitions
Jad C. Halimeh, Daniele Trapin, Maarten Van Damme +1
In recent years, dynamical quantum phase transitions (DQPTs) have emerged as a useful theoretical concept to characterize nonequilibrium states of quantum matter. DQPTs are marked…
Unitary long-time evolution with quantum renormalization groups and artificial neural networks
Heiko Burau, Markus Heyl
In this work we combine quantum renormalization group approaches with deep artificial neural networks for the description of the real-time evolution in strongly disordered quantum…
Variational classical networks for dynamics in interacting quantum matter
Roberto Verdel, Markus Schmitt, Yi-Ping Huang +2
Dynamics in correlated quantum matter is a hard problem, as its exact solution generally involves a computational effort that grows exponentially with the number of constituents. W…
Quantum entanglement recognition
Jun Yong Khoo, Markus Heyl
Entanglement constitutes a key characteristic feature of quantum matter. Its detection, however, still faces major challenges. In this letter, we formulate a framework for probing…
Reinforcement Learning for Digital Quantum Simulation
Adrien Bolens, Markus Heyl
Digital quantum simulation is a promising application for quantum computers. Their free programmability provides the potential to simulate the unitary evolution of any many-body Ha…
Nonlinear entanglement growth in inhomogeneous spacetimes
Arkadiusz Kosior, Markus Heyl
Entanglement has become central for the characterization of quantum matter both in and out of equilibrium. In a dynamical context entanglement exhibits universal linear temporal gr…
Unconventional critical exponents at dynamical quantum phase transitions in a random Ising chain
Daniele Trapin, Jad C. Halimeh, Markus Heyl
Dynamical quantum phase transitions (DQPTs) feature singular temporal behavior in transient quantum states during nonequilibrium real-time evolution. In this work we show that DQPT…
Non-Hermitian Kibble-Zurek mechanism with tunable complexity in single-photon interferometry
Peng Xue, Lei Xiao, Dengke Qu +7
Non-Hermitian descriptions of quantum matter have seen impressive progress recently, with major advances in understanding central aspects such as their topological properties or th…
Discrete truncated Wigner approach to dynamical phase transitions in Ising models after a quantum quench
Reyhaneh Khasseh, Angelo Russomanno, Markus Schmitt +2
By means of the discrete truncated Wigner approximation we study dynamical phase transitions arising in the steady state of transverse-field Ising models after a quantum quench. St…
Signatures of quantum phase transitions after quenches in quantum chaotic one-dimensional systems
Asmi Haldar, Krishnanand Mallayya, Markus Heyl +3
Quantum phase transitions are central to our understanding of why matter at very low temperatures can exhibit starkly different properties upon small changes of microscopic paramet…
Disorder-free localization in an interacting two-dimensional lattice gauge theory
P. Karpov, R. Verdel, Y. -P. Huang +2
Disorder-free localization has been recently introduced as a mechanism for ergodicity breaking in low-dimensional homogeneous lattice gauge theories caused by local constraints imp…
Quantum Fisher information measurement and verification of the quantum Cramér-Rao bound in a solid-state qubit
Min Yu, Yu Liu, Pengcheng Yang +8
The quantum Cramér-Rao bound sets a fundamental limit on the accuracy of unbiased parameter estimation in quantum systems, relating the uncertainty in determining a parameter to th…
Geometrical quench and dynamical quantum phase transition in the lattice
Balázs Gulácsi, Markus Heyl, Balázs Dóra
We investigate quantum quenches and the Loschmidt echo in the two dimensional, three band model, a close descendant of the dice lattice. By adding a chemical potential to t…
Anomalous diffusion in particle-hole symmetric many-body localized systems
Giuseppe De Tomasi, Daniele Trapin, Markus Heyl +1
In this work we probe the dynamics of the particle-hole symmetric many-body localized (MBL) phase. We provide numerical evidence that it can be characterized by an algebraic propag…
