The electric-field-driven intermediate state of three-dimensional superconductors
Ion Cojocari, Enzo Andreani, Paola Verniere +5
The coexistence of superconductivity and finite electric fields may enable access to intriguing forms of electronic states. We demonstrate the emergence of an intermediate state in…
Conductance switching and nonequilibrium phase coexistence in superconductors with intermediate bias
Shamashis Sengupta
Superconducting systems may display different types of nonequilibrium states depending on the specific constraints imposed for measurement. We probe current-voltage relations of th…
Born-limit scattering and pair-breaking crossover in d-wave superconductivity of (TMTSF)2ClO4
Shota Yano, Kazumi Fukushima, Katsuki Kinjo +8
In the quasi-one-dimensional organic unconventional superconductor (TMTSF)2ClO4, the randomness of the non-centrosymmetric ClO4 anions can be experimentally controlled by adjusting…
Pressure Induced Anomalous Metal in the Vicinity of the Superconductor Insulator Transition
Roy G. Cohen Song, Mark Nikolaevsky, Amitay Cohen +4
The Superconductor-to-Insulator Transition (SIT) in two-dimensional superconductors occurs due to a competition between superconductivity, quantum interferences, Coulomb interactio…
Transverse resistance due to electronic inhomogeneities in superconductors
Shamashis Sengupta, Alireza Farhadizadeh, Joe Youssef +8
Phase transitions in many-body systems are often associated with the emergence of spatial inhomogeneities. Such features may develop at microscopic lengthscales and are not necessa…
Spontaneous voltage peaks in superconducting Nb channels without engineered asymmetry
Shamashis Sengupta, Miguel Monteverde, Sara Loucif +3
Rectification effects in solid-state devices are a consequence of nonreciprocal transport properties. This phenomenon is usually observed in systems with broken inversion symmetry.…
Density-tuned isotherms and dynamic change at phase transition in a gate-controlled superconducting system
Shamashis Sengupta, Miguel Monteverde, Anil Murani +3
Two-dimensional electron gases in SrTiO3-based heterostructures provide a platform to study the real-time evolution of the macroscopic state with a variation of the carrier density…
Size Dependence in Flux-Flow Hall Effect using Time-Dependent Ginzburg-Landau Equations
Vineet Punyamoorty, Aditya Malusare, Shamashis Sengupta +2
We study the Hall effect in square, planar type-II superconductors using numerical simulations of time dependent Ginzburg-Landau (TDGL) equations. The Hall field in some type-II su…
Gate-tunable superconductivity at SrTiO3 surface realized by Al layer evaporation
Shamashis Sengupta, Emilie Tisserond, Florence Linez +8
Electronic properties of low dimensional superconductors are determined by many-body-effects. This physics has been studied traditionally with superconducting thin films, and in re…
