The density-matrix renormalization group (DMRG) is a numerical algorithm for the efficient
truncation of the Hilbert space of low-dimensional strongly correlated quantum systems …

The density matrix renormalization group (DMRG) has become a powerful numerical
method that can be applied to low-dimensional strongly correlated fermionic and bosonic …

Recent developments in the theoretical investigation of the one-dimensional Kondo lattice
model by using the density matrix renormalization group (DMRG) method are discussed in …

In these lecture notes, we present a pedagogical review of a number of related numerically
exact approaches to quantum many‐body problems. In particular, we focus on methods …

Using the recently developed transfer-matrix renormalization group method, we have
studied the thermodynamic properties of two-leg antiferromagnetic ladders in a magnetic …

We present an algorithm for studying quantum systems at finite temperature using
continuous matrix product operator representation. The approach handles both short-range …

Using variational matrix product states, we analyze the finite temperature behavior of a half-
filled periodic Anderson model in one dimension, a prototypical model of a Kondo insulator …

We propose a path-integral variant of the density-matrix renormalization group method to
calculate real-time correlation functions at arbitrary finite temperatures. To illustrate the …

The Kondo lattice model (KLM) on the 2-dimensional triangular lattice is studied by bond
fermion theory. Three-sublattice Néel order (AF) and partial Kondo screening (PKS) are …

We have measured the optical conductivity σ (ω) of Yb 1− x Lu x B 12 (0<~ x<~ 1), where the
system evolves from a Kondo semiconductor at x= 0 to a nonmagnetic metal at x= 1. For x …
