We investigate the induced superconducting pair correlations in junctions between a conventional spin-singlet $s$-wave superconductor and a disordered normal metal. Decomposing the pair amplitude based on its symmetries in the time domain, we demonstrate that the odd-time, or equivalently odd-frequency, spin-singlet $p$-wave correlations are both significant in size and entirely robust against random non-magnetic disorder. We find that these odd-frequency correlations can even be generated by…

Realization of 0 - $\pi$ states in SFIS Josephson junctions. The role of spin-orbit interaction and lattice impurities
Josephson devices with ferromagnetic barriers have been widely studied. Much less is known when the ferromagnetic layer is insulating. In this manuscript we investigate the transport properties of
Real-space spectral simulation of quantum spin models: Application to the Kitaev-Heisenberg model
The proliferation of quantum fluctuations and long-range entanglement presents an outstanding challenge for the numerical simulation of interacting spin systems with exotic ground states. Here, we


Odd-frequency pairing in normal-metal/superconductor junctions
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 a
Odd-frequency superconducting pairing in junctions with Rashba spin-orbit coupling
We consider NS and SNS junctions based on one-dimensional nanowires with Rashba spin-orbit coupling and proximity-induced $s$-wave spin singlet superconductivity and analytically demonstrate how both
Theory of the proximity effect in junctions with unconventional superconductors.
It is shown that the pair amplitude in a DN belongs, respectively, to an ESE, OTE, O TE, and ESE pairing state since only the even-parity s-wave pairing is possible due to the impurity scattering.
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 these
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 inhomogeneity

The manifestation of odd-frequency pairing in conventional superconductor/normal (S/N) proximity systems and its relation to the classical McMillan-Rowell oscillations are discussed.
Conductance signatures of odd-frequency superconductivity in quantum spin Hall systems using a quantum point contact
Topological superconductors give rise to unconventional superconductivity, which is mainly characterized by the symmetry of the superconducting pairing amplitude. However, since the symmetry of the
Even-parity spin-triplet superconductivity in disordered electronic systems.
A purely electronic mechanism for superconductivity in disordered Fermi systems is given. It is based on long-time-tail effects in electronic correlations, is strongest in two-dimensional systems,
Odd-frequency superconducting pairing in one-dimensional systems
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,
Signature of magnetic-dependent gapless odd frequency states at superconductor/ferromagnet interfaces
Scanning tunnelling spectroscopy of Nb superconductor films proximity coupled to epitaxial Ho reveals pronounced changes to the Nb subgap superconducting density of states on driving the Ho through a metamagnetic transition from a helical antiferromagnetic to a homogeneous ferromagnetic state for which a BCS-like gap is recovered.
