Coulomb interaction effects on the Majorana states in quantum wires
Andrei Manolescu, D. C. Marinescu, Tudor D. Stanescu
The stability of the Majorana modes in the presence of a repulsive interaction is studied in the standard semiconductor wire - metallic superconductor configuration. The effects of…
Excitation of radial collective modes in a quantum dot: Beyond linear response
Vidar Gudmundsson, Sigtryggur Hauksson, Arni Johnsen +4
We compare the response of five different models of two interacting electrons in a quantum dot to an external short lived radial excitation that is strong enough to excite the syst…
Impact of a circularly polarized cavity photon field on the charge and spin flow through an Aharonov-Casher ring
Thorsten Arnold, Chi-Shung Tang, Andrei Manolescu +1
We explore the influence of a circularly polarized cavity photon field on the transport properties of a finite-width ring, in which the electrons are subject to spin-orbit and Coul…
Geometry and linearly polarized cavity photon effects on the charge and spin currents of spin-orbit interacting electrons in a quantum ring
Thorsten Arnold, Chi-Shung Tang, Andrei Manolescu +1
We calculate the persistent spin current inside a quantum ring as a function of the strength of the Rashba or Dresselhaus spin-orbit interaction. We provide analytical results for…
Electron transport through a quantum dot assisted by cavity photons
Nzar Rauf Abdullah, Chi-Shung Tang, Andrei Manolescu +1
We investigate transient transport of electrons through a single-quantum-dot controlled by a plunger gate. The dot is embedded in a finite wire that is weakly coupled to leads and…
Coherent Nonlinear Quantum Model for Composite Fermions
Gilbert Reinisch, Vidar Gudmundsson, Andrei Manolescu
Originally proposed by Read [1] and Jain [2], the so-called "composite-fermion" is a phenomenological attachment of two infinitely thin local flux quanta seen as nonlocal vortices…
Dike states in multiple quantum dots
Anna Sitek, Andrei Manolescu
We present a theoretical study of the collective optical effects which can occur in groups of three and four quantum dots. We define conditions for stable subradiant (dark) states,…
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…
Thermoelectric Current and Coulomb-Blockade Plateaus in a Quantum Dot
Kristinn Torfason, Andrei Manolescu, Sigurdur I. Erlingsson +1
A Generalized Master Equation (GME) is used to study the thermoelectric currents through a quantum dot in both the transient and steady-state regime. The two semi-infinite leads ar…
