This article reviews odd-frequency (odd-ω) pairing with a focus on superconducting systems.
Since Berezinskii introduced the concept of odd-frequency order in 1974 it has been viewed …

Using numerical results from density matrix renormalization group (DMRG) calculations for
the tJ model, on systems as large as 10× 7, we examine the structure of the one and two …

We review current attempts to characterize the underlying nature of the hidden order in URu
2 Si 2. A wide variety of experiments point to the existence of two order parameters: a large …

We examine how the properties of a single-channel Kondo lattice model are modified by
additional screening channels. Contrary to current wisdom, additional screening channels …

Abstract Employing a quantum Monte Carlo simulation we find a pairing instability in the
normal state of the infinite dimensional periodic Anderson model. Superconductivity arises …

We study the asymmetric periodic Anderson model numerically by using a dynamical mean
field approximation (DMFA) which is basically a mapping onto a self-consistent single site …

This thesis reports results on three problems in correlated electron physics. The main
problem of interest is the dissipative dynamics of a magnetic nano-structure (cluster of …
