Imaging superconducting weak spots through vortex-assisted THz near-field photovoltage

Sergio J. Salvía-Fernández, Ekaterina Khestanova, Zoe Velluire-Pellat +9

Nanoscale inhomogeneities are a defining feature of many superconducting materials, yet their local electromagnetic response has remained difficult to access experimentally. This i…

Revealing intrinsic superconductivity of the Nb/BiSbTeSe interface

Andrei Kudriashov, Ian Babich, Razmik A. Hovhannisyan +7

Typically, topological superconductivity is reachable via proximity effect by a direct deposition of superconductor (S) on top of a topological insulator (TI) surface. Here we obse…

Dynamical Control of Interlayer Excitons and Trions in WSe/MoWSe Heterobilayer via Tunable Near-Field Cavity

Yeonjeong Koo, Hyeongwoo Lee, Tatiana Ivanova +5

Emerging photo-induced excitonic processes in transition metal dichalcogenide (TMD) heterobilayers, e.g., coupling, dephasing, and energy transfer of intra- and inter-layer exciton…
