Recent advances in the development of Josephson scanning tunneling spectroscopy (JSTS) have opened a new path for the exploration of unconventional superconductors. We demonstrate that the critical current I_{c}, measured via JSTS, images the spatial form of the superconducting order parameter in d_{x^{2}-y^{2}}-wave superconductors around defects and in the Fulde-Ferrell-Larkin-Ovchinnikov state. Moreover, we show that I_{c} probes the existence of phase-incoherent superconducting correlations…

Quasiclassical circuit theory of contiguous disordered multiband superconductors
We consider a general problem of a Josephson contact between two multiband superconductors with coexisting superconducting and magnetic phases. As a particular example, we use the quasiclassical
Quantum engineered Kondo lattices
TLDR
The quantum engineering of nanoscale Kondo lattices – Kondo droplets – exemplifying nanoscopic replicas of heavy-fermion materials is investigated and a new quantum phenomenon – the Kondo echo – a signature of droplets containing Kondo holes functioning as direct probes of spatially extended, quantum-coherent Kondo cloud correlations is reported.
Discovery of a Cooper-pair density wave state in a transition-metal dichalcogenide
Imaging an exotic state Among the most intriguing of the many phases of cuprate superconductors is the so-called pair density wave (PDW) state. PDW is characterized by a spatially modulated density

TLDR
The local density of states is found to be sensitive to impurity-induced resonances and to the symmetry of the order parameter.

TLDR
Measurements of the heat capacity and magnetization show that, for particular orientations of an external magnetic field, superconductivity in the heavy-fermion material CeCoIn5 is enhanced through the magnetic moments (spins) of individual electrons.

A number of spectacular experimental anomalies have been discovered recently in certain cuprates, notably La2−xBaxCuO4 and La1.6−xNd0.4SrxCuO4, which show unidirectional spin and charge order (known

The observation of vortices in superconductors was a major breakthrough in developing the conceptual background for superconducting applications. Each vortex carries a flux quantum, and the magnetic

TLDR
For finite density of impurities in a {ital d}-wave superconductor, the Mott criterion for the metal-insulator transition in this band is discussed, and the explicit form of the bound-state wave function is found to decay exponentially with angle-dependent range.
Model for the temperature dependence of the quasiparticle interference pattern in the measured scanning tunneling spectra of underdoped cuprate superconductors
In this paper we explore the behavior of the quasi-particle interference pattern (QPI) of scanning tunneling microscopy as a function of temperature, $T$. After insuring a minimal consistency with
