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 …

The strong disorder RG approach for random systems has been extended in many new
directions since our previous review of 2005 [F. Igloi, C. Monthus, Phys. Rep. 412, 277 …

We develop a nonequilibrium increment method to compute the Rényi entanglement
entropy and investigate its scaling behavior at the deconfined critical (DQC) point via large …

The reduced density matrix of many-body systems possessing an additive conserved
quantity can be decomposed in orthogonal sectors which can be independently analyzed …

We develop a nonequilibrium increment method in quantum Monte Carlo simulations to
obtain the Rényi entanglement entropy of various quantum many-body systems with high …

We investigate the logarithmic negativity in strongly disordered spin chains in the random-
singlet phase. We focus on the spin-1 2 random Heisenberg chain and the random XX …

In the emerging quantum internet, complex network topology could lead to efficient quantum
communication and robustness against failures. However, there are concerns about …

We introduce an adaptive-weighted tree tensor network for the study of disordered and
inhomogeneous quantum many-body systems. This Ansatz is assembled on the basis of the …

The discovery of novel entanglement patterns in quantum many-body systems is a
prominent research direction in contemporary physics. Here we provide the example of a …

A bstract We study the structure of divergences and universal terms of the entanglement and
Rényi entropies for singular regions. First, we show that for (3+ 1)-dimensional free …
