Conductance Oscillations in a Topological Insulator-Disordered Superconductor Hybrid Interface
Jagadis Prasad Nayak, Aviad Frydman, Gopi Nath Daptary
We report on the observation on proximity-induced superconductivity in the topological insulator BiSbTeSe2 coupled to a disordered superconductor, amorphous indium oxide (a-InO). R…
Weak Electron-Phonon Coupling Is Insufficient to Generate Significant CISS in Two-Terminal Transport
Vipul Upadhyay, Amikam Levy
A central open question in chiral-induced spin selectivity (CISS) is whether weak electron-phonon coupling in a helical molecular junction can generate a sizable spin polarization…
Current cross-correlation spectroscopy of Majorana bound states
Michael Ridley, Eliahu Cohen, Christian Flindt +1
The clock speed of topological quantum computers based on Majorana zero mode (MZM)-supporting nanoscale devices is limited by the time taken for electrons to traverse the device. W…
The spinterface mechanism for the chiral-induced spin selectivity effect: A Critical Perspective
Subhajit Sarkar, Amos Sharoni, Oliver L. A. Monti +1
The chiral-induced spin selectivity (CISS) effect, whereby chiral molecules preferentially transmit electrons of one spin orientation, remains one of the most intriguing and debate…
Modified Quantum Wheatstone Bridge based on current circulation
Vipul Upadhyay, Rahul Marathe
We investigate a simple fermionic system designed to detect an unknown hopping rate between two sites by analyzing current circulation. The system exploits geometric asymmetry and…
Hydrodynamic Coulomb drag in odd electron liquids
Dmitry Zverevich, Dmitri B. Gutman, Alex Levchenko
We consider the problem of Coulomb drag resistance in bilayers of electron liquids with spontaneously broken time-reversal symmetry. In the hydrodynamic regime, the viscosity tenso…
