Supercritical fluid of quantum electrons in three-dimensional superconducting fullerides
Xinying Li, Yuki Matsuda, Chongli Yang +10
The supercritical fluid (SCF) of quantum electrons at the Mott metal-insulator transition without symmetry breaking is one of the most elusive phenomena in strongly correlated elec…
Nonreciprocal Equilibrium Josephson Effect of Arbitrary Periodicity from Poor Man's Majorana Zero Modes
Panagiotis Kotetes, Mercè Roig, Brian M. Andersen
We show that the Josephson diode effect becomes possible when two coupled antiferromagnetic dimers of point-like magnetic adatoms are deposited on top of a Rashba superconductor. T…
Zero-field superconducting vortices and Majorana zero modes pinned by magnetic islands in correlated Rashba systems
Panagiotis Kotetes, Brian M. Andersen
We propose a route for pinning zero-field superconducting vortices in systems which are exchange-coupled to magnetic islands and feature Rashba spin-orbit coupling. We consider isl…
Green Function Invariants for Floquet Topological Superconductivity Induced by Proximity Effects
Mohamed Assili, Panagiotis Kotetes
We bring forward a Green function approach for the prediction of Floquet topological phases in driven superconductor-semiconductor hybrids. Although it is common to treat the super…
Survival and Detection of Symmetry-Protected Topology in Loop Quenches
Nicolò Forcellini, Miklós Horváth, Panagiotis Kotetes
We explore a class of dynamical protocols - that we term loop quenches - which are tailored for the study of symmetry-protected topological (SPT) systems. In loop quenches, SPT pha…
