Observation of Critical Current Minimum in Super-Honeycomb Josephson Junction Arrays
Melissa Mikalsen, Alexander-Georg Penner, Samuel D. Escribano +5
Superconductor-semiconductor Josephson junction arrays are a uniquely tunable platform for studying collective quantum phenomena, particularly in the regime where localized Andreev…
Engineered broadband Purcell protection using a shared filter for multiplexed superconducting qubits
Samuel D. Escribano, Yael Kriheli, Samuel Goldstein +2
We propose a broadband Purcell-protection scheme based on a single shared filter integrated directly into the feedline, enabling simultaneous protection of multiple qubits in a com…
Effective conduction-band model for zincblende III-V semiconductors in the presence of strain: tuning the properties of bulk crystals and nanostructures
Samuel D. Escribano, Alfredo Levy Yeyati, Elsa Prada
Strain provides a powerful knob to tailor the electronic properties of semiconductors. Simple yet accurate approximations that capture strain effects in demanding simulations of me…
Phase-controlled minimal Kitaev chain in multiterminal Josephson junctions
Samuel D. Escribano, Anders Enevold Dahl, Karsten Flensberg +1
We propose a nanodevice based on multi-terminal Josephson junctions for the creation and detection of poor man's Majorana (PMM) modes. The device consists of a double three-termina…
Intertwined topological phases in TaAs2 nanowires with giant magnetoresistance and quantum coherent surface transport
Anand Roy, Anna Eyal, Roni Majlin Skiff +7
Nanowires (NWs) of topological materials are emerging as an exciting platform to probe and engineer new quantum phenomena that are hard to access in bulk phase. Their quasi-one-dim…

Following significant progress in the visualization and characterization of hybrid superconducting-semiconducting systems, greatly propelled by reports of Majorana zero modes in na…
InP/GaSb core-shell nanowires: a novel hole-based platform with strong spin-orbit coupling for full-shell hybrid devices
Andrea Vezzosi, Carlos Payá, Paweł Wójcik +4
Full-shell hybrid nanowires (NWs), structures comprising a superconductor shell that encapsulates a semiconductor (SM) core, have attracted considerable attention in the search for…
Phenomenology of Majorana zero modes in full-shell hybrid nanowires
Carlos Payá, Samuel D. Escribano, Andrea Vezzosi +4
Full-shell nanowires have been proposed as an alternative nanowire design in the search of topological superconductivity and Majorana zero modes (MZMs). They are hybrid nanostructu…
The feedback driven atomic scale Josephson microscope
Samuel D. Escribano, Víctor Barrena, David Perconte +10
The ultimate spatial limit to establish a Josephson coupling between two superconducting electrodes is an atomic-scale junction. The Josephson effect in such ultrasmall junctions h…
Semiconductor-ferromagnet-superconductor planar heterostructures for 1D topological superconductivity
Samuel D. Escribano, Andrea Maiani, Martin Leijnse +5
Hybrid structures of semiconducting (SM) nanowires, epitaxially grown superconductors (SC), and ferromagnetic-insulator (FI) layers have been explored experimentally and theoretica…
