During the past 15 years a new field has emerged, which combines superconductivity and
spintronics, with the goal to pave a way for new types of devices for applications combining …

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 …

This review considers unusual effects in superconductor-ferromagnet structures, in
particular, the triplet component of the condensate generated in those systems. This …

We present a powerful method for calculating the thermodynamic properties of infinite-
dimensional Hubbard-type models using an exact diagonalization of an Anderson model …

The ordinary single-channel Kondo model consists of one or more spin-½ local moments
interacting antiferromagnetically with conduction electrons in a metal. This model has …

Using selection rules imposed by the Pauli principle, we classify pairing correlations
according to their symmetry properties with respect to spin, momentum, and energy. We …

Odd-frequency superconductivity represents a truly unconventional ordered state which, in
contrast to conventional superconductivity, exhibits pair correlations which are odd in …

We point out that essentially all multiband superconductors have an odd-frequency pairing
component, as follows from a general symmetry analysis of even-and odd-frequency pairing …

We discuss the possibility that heavy-fermion superconductors involve odd-frequency triplet
pairing. A key technical innovation here is a Majorana representation for the local moments …

We reformulate the two-channel Kondo model to explicitly remove the unscattered charge
degrees of freedom. This procedure permits us to move the non-Fermi-liquid fixed point to …
