Interferometric evidence of non-volatile anomalous phase shifts in exchange-spin-split Josephson supercurrent diodes
Kun-Rok Jeon, Jae-Keun Kim, Jiho Yoon +5
The recent realization of zero-field, polarity-reversible supercurrent rectification in proximity-magnetized Rashba-type Pt Josephson junctions (JJs) enables the development of sup…
Josephson vortex-based memory
Dmitrii S. Kalashnikov, Vsevolod I. Ruzhitskiy, Andrey G. Shishkin +5
Josephson junctions are currently used as base elements of superconducting logic systems. Long enough junctions subject to magnetic field host quantum phase 2π-singularities - Jose…
Nernst response, viscosity and mobile entropy in vortex liquids
Kamran Behnia
In a liquid of superconducting vortices, a longitudinal thermal gradient generates a transverse electric field. This Nernst signal peaks at an intermediate temperature and magnetic…
Rationalizing doping and electronic correlations in LaFeAs
Tommaso Gorni, Diego Florez-Ablan, Luca de' Medici
We compute the electronic properties of the normal state of uncollapsed LaFeAs, taking into account local dynamical correlations by means of slave-spin mean-field+density-f…
Local density of state fluctuations in 2D superconductor as a probe of quantum diffusion
Mathieu Lizée, Matthias Stosiek, Christophe Brun +2
The interplay of superconductivity and disorder generates a wealth of complex phenomena. In particular, the peculiar structure of diffusive electronic wavefunctions is predicted to…
Superfluid stiffness of a KTaO3-based two-dimensional electron gas
S. Mallik, G. Ménard, G. Saïz +6
After almost twenty years of intense work on the celebrated LaAlO3/SrTiO3 system, the recent discovery of a superconducting two-dimensional electron gases (2-DEG) in (111)-oriented…
