Transport in magnetic-topological-insulator nanoribbons containing multiple superconductor-proximitized sectors
Javier Osca, Sungguen Ryu, Rosa López +1
Transport in devices with multiple proximitized sectors depends heavily on the complex phases of the pairing gaps of those sectors. We investigate magnetic topological insulator na…
An optimal superconducting hybrid machine
Rosa Lopez, Jong Soo Lim, Kun Woo Kim
Optimal engine performances are accomplished by quantum effects. Here we explore two routes towards ideal engines, namely (1) quantum systems that operate as hybrid machines being…
Beating Carnot efficiency with periodically driven chiral conductors
Sungguen Ryu, Rosa López, Llorenç Serra +1
Classically, the power generated by an ideal thermal machine cannot be larger than the Carnot limit. This profound result is rooted in the second law of thermodynamics. A hot quest…
Aharonov-Bohm and Aharonov-Casher effects in double quantum dot Josephson junction
Damian Tomaszewski, Piotr Busz, Rosa Lopez +3
We analyze a Josephson junction between two superconductors interconnected through a normal-state nanostructure made of two parallel nanowires with embedded quantum dots. We study…
Aharonov-Bohm and Aharonov-Casher effects for local and nonlocal Cooper pairs
Damian Tomaszewski, Piotr Busz, Rosa Lopez +3
We study combined interference effects due to the Aharonov-Bohm (AB) and Aharonov-Casher (AC) phases in a Josephson supercurrent of local and nonlocal (split) Cooper pairs. We anal…
Nonlinear chiral refrigerators
David Sanchez, Rafael Sanchez, Rosa Lopez +1
We investigate a mesoscopic refrigerator based on chiral quantum Hall edge channels. We discuss a three-terminal cooling device in which charge transport occurs between a pair of v…
