Interplay between altermagnetism and superconductivity in two dimensions: intertwined symmetries and singlet-triplet mixing
Kinga Jasiewicz, Paweł Wójcik, Michał Nowak +1
We study the interplay between altermagnetism and unconventional superconductivity for the case of two-dimensional square- and triangular-lattice systems. Our approach is based on…
Magnetic-field-free parity-protected qubit based on a narrow altermagnet Josephson junction
Sakineh Vosoughi-nia, Michał P. Nowak
Altermagnets provide a new route to engineer superconducting circuits without magnetic fields. We theoretically study the Andreev bound state (ABS) spectrum of a finite-width altrm…
Broad nonlocal spectrum in the Pb-InSb hybrid three terminals for potential realization of Kitaev chains
Guoan Li, Xiaofan Shi, Ruixuan Zhang +21
Hybrid superconductor-semiconductor(SC-SM) nanowires remain one of the foremost platforms for engineering topological superconductivity and Majorana zero modes(MZMs) towards fault-…
Enhanced and modulable induced superconducting gap and effective Landé g-factor in Pb-InSb hybrid devices
Guoan Li, Xiaofan Shi, Ziwei Dou +21
The hybrid system of a conventional superconductor (SC) on a semiconductor (SM) nanowire with strong spin-orbit coupling (SOC) represents a promising platform for achieving topolog…
Scanning gate microscopy probing of anisotropic electron flow in a two dimensional electron gas at the (110) interface: A theoretical investigation
M. P. Nowak, M. Zegrodnik, D. Grzelec +3
We theoretically investigate the anisotropic dispersion features of a two dimensional electron gas at the (110) oriented interfaces, as revealed…
Versatile Method of Engineering the Band Alignment and the Electron Wavefunction Hybridization of Hybrid Quantum Devices
Guoan Li, Xiaofan Shi, Ting Lin +23
With the development of quantum technology, hybrid devices that combine superconductors (S) and semiconductors (Sm) have attracted great attention due to the possibility of enginee…
Durability of the superconducting gap in Majorana nanowires under orbital effects of a magnetic field
P. Wójcik, M. P. Nowak
We analyze the superconducting gap in semiconductor/superconductor nanowires under orbital effects of a magnetic field in the weak- and strong-hybridization regimes using an univer…
Renormalization of the Majorana bound state decay length in a perpendicular magnetic field
M. P. Nowak, P. Wójcik
Orbital effects of a magnetic field in a proximitized semiconductor nanowire are studied in the context of the spatial extent of Majorana bound states. We develop analytical model…
Conductance through a helical state in an InSb nanowire
Jakob Kammhuber, Maja C Cassidy, Fei Pei +7
The motion of an electron and its spin are generally not coupled. However in a one dimensional material with strong spin-orbit interaction (SOI) a helical state may emerge at finit…
Spin current source based on a quantum point contact with local spin-orbit interaction
M. P. Nowak, B. Szafran
Proposal for construction of a source of spin-polarized current based on quantum point contact with local spin-orbit interaction is presented. We show that spin-orbit interaction p…
Simulations of electric-dipole spin resonance for spin-orbit-coupled quantum dots in Overhauser field: fractional resonances and selection rules
E. N. Osika, B. Szafran, M. P. Nowak
We consider spin rotations in single- and two-electron quantum dots that are driven by external AC electric field with two mechanisms that couple the electron spatial motion and th…
