Enhancing supercurrent-based inertial sensing via interactions in atomtronic angular accelerometers
S. Carmona-López, A. Matos-Abiague, F. Isaule +1
We theoretically investigate supercurrents of ultracold atoms in angularly ac-shaken ring lattices subjected to external rotation. Our results demonstrate how these supercurrents c…
Anisotropic Superconducting Diode Effect in Planar Josephson Junctions
Abhishek Chilampankunnel Prasannan, Baris Pekerten, Nowar Alashkar +1
We theoretically investigate the magnetic and crystalline anisotropies of the superconducting diode effect (SDE) in proximitized planar Josephson junctions (JJs) with coexisting Ra…
Signatures of Topological Superconductivity and Josephson Diode Effects on the Magnetocurrent-Phase Relation of Planar Josephson Junctions
B. Pekerten, A. Chilampankunnel Prasannan, A. Matos-Abiague
We present a theoretical study of proximitized planar Josephson junctions (JJs) with Rashba spin-orbit coupling (SOC) subject to an in-plane magnetic field and demonstrate that the…
Majorana edge and end states in planar Josephson junctions
A. P. Garrido, P. A. Orellana, A. Matos-Abiague
We theoretically investigate the localization properties of Majorana states (MSs) in proximitized, planar Josephson Junctions (JJs) oriented along different crystallographic orient…
Beyond the standard model of topological Josephson junctions: From crystalline anisotropy to finite-size and diode effects
Barış Pekerten, David Brandão, Bailey Bussiere +6
A planar Josephson junction is a versatile platform to realize topological superconductivity over a large parameter space and host Majorana bound states. With a change in Zeeman fi…
Superconducting Diode Effect in Quantum Spin Hall Insulator-based Josephson Junctions
Benedikt Scharf, Denis Kochan, Alex Matos-Abiague
The superconducting diode effect (SDE) is a magneto-electric phenomenon where an external magnetic field imparts a non-zero center-of-mass momentum to Cooper pairs, either facilita…
Superconducting Diode Effect Sign Change in Epitaxial Al-InAs Josepshon Junctions
Neda Lotfizadeh, William F. Schiela, Barış Pekerten +5
There has recently been a surge of interest in studying the superconducting diode effect (SDE) partly due to the possibility of uncovering the intrinsic properties of a material sy…
Rashba spin-orbit coupling enhanced magnetoresistance in junctions with one ferromagnet
Chenghao Shen, Ranran Cai, Alex Matos-Abiague +3
We explain how Rashba spin-orbit coupling (SOC) in a two-dimensional electron gas (2DEG), or in a conventional -wave superconductor, can lead to a large magnetoresistance even w…
Tunneling anisotropic magnetoresistance and spin-orbit coupling in Fe/GaAs/Au tunnel junctions
J. Moser, A. Matos-Abiague, D. Schuh +3
We report the observation of tunneling anisotropic magnetoresistance effect (TAMR) in the epitaxial metal-semiconductor system Fe/GaAs/Au. The observed two-fold anisotropy of the r…
