Flat band driven competing charge and spin instabilities in the altermagnet CrSb
A. Korshunov, M. Alkorta, C. -Y. Lim +8
The confinement of electronic wavefunctions in momentum space can give rise to flat electronic bands, where the quenching of kinetic energy enhances the density of states and ampli…
Magnetic flux controlled current phase relationship in double Quantum Dot Josephson junction
Yiyan Wang, Cong Li, Bing Dong
In this work, we study a Josephson junction with parallel-connected quantum dots (QDs) threaded by a magnetic flux in the central region. We discretize the superconducting (SC) ele…
Quantum phase transition in a double quantum dot Josephson junction driven by electron-electron interactions
Cong Li, Yiyan Wang, Bing Dong
In this work, we employ a surrogate BCS model with discrete energy levels to investigate a hybrid system comprising two quantum dots (QD1 and QD2), where QD1 is tunnel-coupled to t…
Quantum Resistor-Capacitor Circuit with two Majorana Bound States
Cong Li, Bing Dong
In this paper, we derive the equations of motion for a system composed of a spinless quantum dot coupled to two normal leads and two Majorana bound states (MBSs), utilizing the aux…
