Entanglement in solvable many-particle models
I Peschel - Brazilian Journal of Physics, 2012 - Springer
The five lectures introduce to the description of entanglement in many-particle systems and
review the ground-state entanglement features of standard solvable lattice models. This is …

Density matrix embedding: A simple alternative to dynamical mean-field theory
We introduce density matrix embedding theory (DMET), a quantum embedding theory for
computing frequency-independent quantities, such as ground-state properties, of infinite …

Entanglement spectrum and entropy in topological non-Hermitian systems and nonunitary conformal field theory
We study entanglement properties of free-fermion systems without Hermiticity by use of
correlation matrix and overlap matrix in the biorthogonal basis. We find at a critical point in …

Entanglement entropy of fermions in any dimension and the Widom conjecture
We show that entanglement entropy of free fermions scales faster than area law, as opposed
to the scaling L d-1 for the harmonic lattice, for example. We also suggest and provide …

Quantized response and topology of magnetic insulators with inversion symmetry
We study three-dimensional insulators with inversion symmetry in which other point group
symmetries, such as time reversal, are generically absent. We find that certain information …

Measures of complexity and entanglement in many-fermion systems
There is no unique and widely accepted definition of the complexity measure (CM) of a
many-fermion wave function in the presence of interactions. The simplest many-fermion …

Entanglement and inversion symmetry in topological insulators
Topological band insulators are usually characterized by symmetry-protected surface modes
or quantized linear-response functions (like Hall conductance). Here we present a way to …

Unbiasing fermionic auxiliary-field quantum Monte Carlo with matrix product state trial wavefunctions
In this work, we report, for the first time, an implementation of fermionic auxiliary-field
quantum Monte Carlo (AFQMC) using matrix product state (MPS) trial wavefunctions …

Entanglement entropy of nuclear systems
We study entanglement entropies between the single-particle states of the hole space and
its complement in nuclear systems. Analytical results based on the coupled-cluster method …

Particle number fluctuations, Rényi entropy, and symmetry-resolved entanglement entropy in a two-dimensional Fermi gas from multidimensional bosonization
MT Tan, S Ryu - Physical Review B, 2020 - APS
We revisit the computation of particle number fluctuations and the Rényi entanglement
entropy of a two-dimensional Fermi gas using multidimensional bosonization. In particular …
