This review focuses on the field of quantum entanglement applied to condensed matter
physics systems with strong correlations, a domain which has rapidly grown over the last …

Quantum information theory has considerably helped in the understanding of quantum many-
body systems. The role of quantum correlations and in particular, bipartite entanglement …

We study quantum-impurity models as a platform for quantum thermometry. A single
quantum spin-1 2 impurity is coupled to an explicit, structured, fermionic thermal sample …

When a magnetic impurity exists in a metal, conduction electrons form a spin cloud that
screens the impurity spin. This basic phenomenon is called the Kondo effect,. Unlike electric …

We present a new impurity solver for dynamical mean-field theory based on imaginary-time
evolution of matrix product states. This converges the self-consistency loop on the imaginary …

Impurities or boundaries often impose nontrivial boundary conditions on a gapless bulk,
resulting in distinct boundary universality classes for a given bulk, phase transitions, and …

Magnetic impurities embedded in a metal are screened by the Kondo effect, signaled by the
formation of an extended correlation cloud, the so-called Kondo or screening cloud. In a …

It is desirable to relate entanglement of many-body systems to measurable observables. In
systems with a conserved charge, it was recently shown that the number entanglement …

Quantum entanglement between an impurity and its environment is expected to be central in
quantum impurity problems. We develop a method to compute the entanglement in spin-1/2 …

We calculate entanglement and impurity entropies in a recent holographic model of a
magnetic impurity interacting with a strongly coupled system. There is an RG flow to an IR …
