Odd frequency (odd-$\omega$) electron pair correlations naturally appear at the interface between BCS superconductors and other materials. The detection of odd-$\omega$ pairs, which are necessarily non-local in time, is still an open problem. The main reason is that they do not contribute to static measurements described by time-local correlation functions. Therefore, dynamical measurements, which depend on non-local time correlations, are suitable for detecting these pairs. In this work, we… Expand

Odd-frequency superconducting pairing in Kitaev-based junctions
We investigate odd-frequency superconducting correlations in normal-superconductor (NS) and short superconductor-normal-superconductor (SNS) junctions with the S region described by the Kitaev modelExpand
Odd-frequency superconductivity induced by nonmagnetic impurities
A growing body of literature suggests that odd-frequency superconducting pair amplitudes can be generated in normal-metal-superconductor junctions. The emergence of odd-frequency pairing in theseExpand

We theoretically study the induced odd-frequency pairing states in ballistic normal-metal/superconductor (N/S) junctions where a superconductor has even-frequency symmetry in the bulk and aExpand
Odd-frequency pairing in the Kondo lattice.
TLDR
Two verifiable predictions of the theory are that a Korringa relaxation will fail to develop in heavy-fermion superconductors, even in the limit of strong pair breaking and severe gaplessness and that the hitherto unmeasured NMR relaxation rate at the actinide or rare-earth site will become exponentially activated in the superconducting phase.

Strong odd-frequency correlations in fully gapped Zeeman-split superconductors
TLDR
It is shown that an odd frequency state can be present even if the S/F interface is fully gapped, and a generalized analytical criterium is derived to describe the effect of odd-frequency pairing on the DoS. Expand
Odd-frequency superconductivity
This article reviews odd-frequency (odd-w) pairing with focus on superconducting systems. Since Berezinskii introduced the concept of odd frequency order in 1974 it has been viewed as an exotic andExpand

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

In this article we review recent progress in the understanding of multiband superconductivity and its relationship to odd-frequency pairing. We begin our discussion by reviewing the emergence ofExpand
Symmetries of Pairing Correlations in Superconductor–Ferromagnet Nanostructures
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 observe that inhomogeneityExpand
