Entanglement measures in a nonequilibrium steady state: Exact results in one dimension
Entanglement plays a prominent role in the study of condensed matter many-body systems: Entanglement measures not only quantify the possible use of these systems in quantum information protocols, but
Entanglement spectrum and quantum phase diagram of the long-range XXZ chain
Entanglement is a central feature of many-body quantum systems and plays a unique role in quantum phase transitions. In many cases, the entanglement spectrum, which represents the spectrum of the
Entanglement Hamiltonian of Many-Body Dynamics in Strongly Correlated Systems.
This work investigates quantum quench dynamics of prototypical Bose-Hubbard model using state-of-the-art numerical technique combined with conformal field theory and unveils signatures of the entanglement evolving and information propagating out of equilibrium, from the view of theEntanglement Hamiltonian.
Entanglement dynamics after quantum quenches in generic integrable systems
The time evolution of the entanglement entropy in non-equilibrium quantum systems provides crucial information about the structure of the time-dependent state. For quantum quench protocols, by
Dynamics of charge-resolved entanglement after a local quench
Quantum entanglement and its main quantitative measures, the entanglement entropy and entanglement negativity, play a central role in many body physics. An interesting twist arises when the system
Power-law entanglement growth from typical product states
Generic quantum many-body systems typically show a linear growth of the entanglement entropy after a quench from a product state. While entanglement is a property of the wave function, it is
Symmetry-Resolved Entanglement in Many-Body Systems.
The total entanglement entropy, which scales as lnL, is composed of sqrt[lnL] contributions of individual subsystem charge sectors for interacting fermion chains, or even O(L^{0}) contributions when total spin conservation is also accounted for.
Reduced density matrix and entanglement of interacting quantum field theories with Hamiltonian truncation
Entanglement is the fundamental difference between classical and quantum systems and has become one of the guiding principles in the exploration of highand low-energy physics. The calculation of
Geometric entanglement in integer quantum Hall states
We study the quantum entanglement structure of integer quantum Hall states via the reduced density matrix of spatial subregions. In particular, we examine the eigenstates, spectrum and entanglement
Growth of entanglement entropy under local projective measurements
Non-equilibrium dynamics of many-body quantum systems under the effect of measurement protocols is attracting an increasing amount of attention. It has been recently revealed that measurements may


Entanglement Spectroscopy and its application to the fractional quantum Hall phases
The entanglement spectroscopy, initially introduced by Li and Haldane in the context of the fractional quantum Hall effects, has stimulated an extensive range of studies. The ent anglement spectrum
Fluctuations and entanglement spectrum in quantum Hall states
The measurement of quantum entanglement in many-body systems remains challenging. One experimentally relevant fact about quantum entanglement is that in systems whose degrees of freedom map to free
Entanglement Hamiltonian of the quantum Néel state
2D projected entangled pair states (PEPS) provide a unique framework giving access to detailed entanglement features of correlated (spin or electronic) systems. For a bi-partitioned quantum system,
Measuring entanglement entropy in a quantum many-body system
Making use of the single-site-resolved control of ultracold bosonic atoms in optical lattices, two identical copies of a many-body state are prepared and interfered to directly measure quantum purity, Rényi entanglement entropy, and mutual information.
Increasing entanglement through engineered disorder in the random Ising chain
The ground state entanglement entropy between block of sites in the random Ising chain is studied by means of the Von Neumann entropy. We show that in presence of strong correlations between the
Measuring entanglement entropy of a generic many-body system with a quantum switch.
This work provides a route towards testing the scaling of entanglement in critical systems as a method for a direct experimental detection of topological order and proposes a possible design of the quantum switch, which can be realized in cold atomic systems.
Entanglement in many-body systems
Recent interest in aspects common to quantum information and condensed matter has prompted a flurry of activity at the border of these disciplines that were far distant until a few years ago.
Participation spectroscopy and entanglement Hamiltonian of quantum spin models
Shannon–Rényi entropies and associated participation spectra quantify how much a many-body wave-function is localized in a given configuration basis. Using these tools, we present an analysis of the
Open-system dynamics of entanglement:a key issues review
An overview of recent theoretical and experimental efforts to underpin the dynamics of entanglement under the influence of noise is presented, and how it evolves due to the unavoidable interaction of the entangled system with its surroundings is surveyed.
