Computational quantum transport: a scattering approach perspective
Xavier Waintal, Michael Wimmer, Anton Akhmerov +5
This review is devoted to the different techniques that have been developed to compute the phase-coherent transport properties of quantum nanoelectronic systems connected to electr…
Conductance asymmetries in mesoscopic superconducting devices due to finite bias
André Melo, Chun-Xiao Liu, Piotr Rożek +2
Tunneling conductance spectroscopy in normal metal-superconductor junctions is an important tool for probing Andreev bound states in mesoscopic superconducting devices, such as Maj…
Qsymm: Algorithmic symmetry finding and symmetric Hamiltonian generation
Daniel Varjas, Tomas O. Rosdahl, Anton R. Akhmerov
Symmetry is a guiding principle in physics that allows to generalize conclusions between many physical systems. In the ongoing search for new topological phases of matter, symmetry…
Platform for nodal topological superconductors in monolayer molybdenum dichalcogenides
Lin Wang, Tomas Orn Rosdahl, Doru Sticlet
We propose a platform to realize nodal topological superconductors in a superconducting monolayer of MoX (XS, Se, Te) using an in-plane magnetic field. The bulk nodal points…
Breakdown of the Law of Reflection at a Disordered Graphene Edge
E. Walter, T. Ö. Rosdahl, A. R. Akhmerov +1
The law of reflection states that smooth surfaces reflect waves specularly, thereby acting as a mirror. This law is insensitive to disorder as long as its length scale is smaller t…
Andreev rectifier: a nonlocal conductance signature of topological phase transitions
T. Ö. Rosdahl, A. Vuik, M. Kjaergaard +1
The proximity effect in hybrid superconductor-semiconductor structures, crucial for realizing Majorana edge modes, is complicated to control due to its dependence on many unknown m…
Conductance oscillations of core-shell nanowires in transversal magnetic fields
Andrei Manolescu, George Alexandru Nemnes, Anna Sitek +3
We analyze theoretically electronic transport through a core-shell nanowire in the presence of a transversal magnetic field. We calculate the conductance for a variable coupling be…
Signature of snaking states in the conductance of core-shell nanowires
Tomas Orn Rosdahl, Andrei Manolescu, Vidar Gudmundsson
We model a core-shell nanowire (CSN) by a cylindrical surface of finite length. A uniform magnetic field perpendicular to the axis of the cylinder forms electron states along the l…
Spin and impurity effects on flux-periodic oscillations in core-shell nanowires
Tomas Orn Rosdahl, Andrei Manolescu, Vidar Gudmundsson
We study the quantum mechanical states of electrons situated on a cylindrical surface of finite axial length to model a semiconductor core-shell nanowire. We calculate the conducta…
Snaking states on a cylindrical surface in a perpendicular magnetic field
Andrei Manolescu, Tomas Orn Rosdahl, Sigurdur Erlingsson +2
We calculate electronic states on a closed cylindrical surface as a model of a core-shell nanowire. The length of the cylinder can be infinite or finite. We define cardinal points…
