Spin-polarized Josephson current induced by inhomogeneous altermagnetic interlayers
Wenjun Zhao, Yuri Fukaya, Pablo Burset +3
The pursuit of dissipationless spin supercurrents is a central theme in superconducting spintronics. We propose a field-free Josephson junction using an inhomogeneous altermagnetic…
Engineering subgap states in superconductors by the symmetry of altermagnetism
Bo Lu, Phillip Mercebach, Pablo Burset +4
Combining superconducting and magnetic materials is a promising path to generate exotic interface subgap states. In this regard, altermagnetism is particularly interesting because…
Odd-frequency Pairing in Josephson Junctions Coupled by Magnetic Textures
Ignacio Sardinero, Jorge Cayao, Rubén Seoane Souto +1
Josephson junctions coupled through magnetic textures provide a controllable platform for odd-frequency superconductivity and Majorana physics. Within a tight-binding Green functio…
Floquet-Nambu theory of electron quantum optics with superconductors
Pablo Burset, Benjamin Roussel, Michael Moskalets +1
We present a comprehensive Floquet-Nambu theory to describe the time-dependent quantum transport in mesoscopic circuits involving superconductors. The central object of our framewo…
On-Demand and Tunable Andreev-Conversion of Single-Electron Charge Pulses
Pablo Burset, Benjamin Roussel, Michael Moskalets +1
Electron quantum optics explores coherent single-electron charge pulse propagation in electronic nanoscale circuits akin to table-top photon setups. While past experiments focused…
Topological superconductivity in a dimerized Kitaev chain revealed by nonlocal transport
Rafael Pineda Medina, Pablo Burset, William J. Herrera
Artificial Kitaev chains engineered from semiconducting quantum dots coupled by superconducting segments offer a promising route to realize and control Majorana bound states for to…
