Fast Length-Squared Sampling for Positive-Semidefinite Matrices
Rajarshi Bhattacharjee, Ethan N. Epperly, Cameron Musco +1
We describe a simple rejection-sampling-based algorithm to perform length-squared sampling on an positive-semidefinite (psd) matrix: that is, to sample a column with p…
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…
From Interdependent Networks to Two-Interactions Physical Systems
Yuval Sallem, Nahala Yadid, Xi Wang +5
Recent advances have shown that introducing dependency interactions between two superconducting networks can trigger abrupt, hysteretic normal-superconductor phase transitions. In…
Energy Gap Modulation in Proximitized Superconducting Puddles of Graphene
Yuxiao Wu, Udit Khanna, Eyal Walach +2
We investigated proximity-induced superconductivity in a graphene-insulating InO bilayer system through gate-controlled transport measurements. Distinct oscillations in the differe…
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…
