Key static and dynamic properties of matter—from creation in the Big Bang to evolution into
subatomic and astrophysical environments—arise from the underlying fundamental …

Results about entanglement (or modular) Hamiltonians of quantum many‐body systems in
field theory and statistical mechanics models, and recent applications in the context of …

Topological quantum many-body systems are characterized by a hidden order encoded in
the entanglement between their constituents. While entanglement is often quantified using …

We study the entanglement Hamiltonian for finite intervals in infinite quantum chains for two
different free-particle systems: coupled harmonic oscillators and fermionic hop** models …

We study the continuum limit of the entanglement Hamiltonians of a block of consecutive
sites in massless harmonic chains. This block is either in the chain on the infinite line or at …

Efficient and accurate algorithms for partition function, free energy, and thermal entropy
calculations is of great significance in statistical physics and quantum many-body physics …

We study the unitary time evolution of the entanglement Hamiltonian of a free Fermi lattice
gas in one dimension initially prepared in a domain wall configuration. To this aim, we …

Based on the path integral formulation of the reduced density matrix, we develop a scheme
to overcome the exponential growth of computational complexity in reliably extracting low …

A bstract We report on a systematic replica approach to calculate the subsystem trace
distance for a quantum field theory. This method has been recently introduced in [J. Zhang …

We carry out a comprehensive comparison between the exact modular Hamiltonian and the
lattice version of the Bisognano-Wichmann (BW) one in one-dimensional critical quantum …
