(2019-03-01)In this work, we theoretically model the time-dependent transport through an asymmetric double quantum dot etched in a two-dimensional wire embedded in a far-infrared (FIR) photon cavity. For the transient and the intermediate time regimes, the current ... -
(American Physical Society (APS), 2016-05-31)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 between the nanowire and the attached leads and show how the snaking ...

Enumerations of Permutations Simultaneously Avoiding a Vincular and a Covincular Pattern of Length 3 (University of Waterloo, 2017)Vincular and covincular patterns are generalizations of classical patterns allowing restrictions on the indices and values of the occurrences in a permutation. In this paper we study the integer sequences arising as the enumerations of permutations ...

(American Chemical Society, 2018-04-21)The distinctive prismatic geometry of semiconductor core-shell nanowires leads to complex localization patterns of carriers. Here, we describe the formation of optically active in-gap excitonic states induced by the interplay between localization of ...

(Beilstein Institut, 2019-09-17)Multilayer structures comprising of SiO2/SiGe/SiO2 and containing SiGe nanoparticles were obtained by depositing SiO2 layers using reactive direct current magnetron sputtering (dcMS), whereas, Si and Ge were co-sputtered using dcMS and high-power impulse ...

(Springer Nature, 2017-01-10)We study Coulomb interacting electrons confined in polygonal quantum rings. We focus on the interplay of localization at the polygon corners and Coulomb repulsion. Remarkably, the Coulomb repulsion allows the formation of in-gap states, i.e., ...

The photocurrent generated by photon replica states of an off-resonantly coupled dot-cavity system (Springer Science and Business Media LLC, 2019-10-11)Transport properties of a quantum dot coupled to a photon cavity are investigated using a quantum master equation in the steady-state regime. In the off-resonance regime, when the photon energy is smaller than the energy spacing between the lowest ...

(2020)We studied high power impulse magnetron sputtering (HiPIMS) and different substrate bias for the epitaxial growth of Cu film on Cu (111) substrate by molecular dynamics simulation. We assumed a fully ionized deposition flux to represent the high ...

(MDPI AG, 2019-05-14)We theoretically investigate thermoelectric effects in a quantum dot system under the influence of a linearly polarized photon field confined to a 3D cavity. A temperature gradient is applied to the system via two electron reservoirs that are connected ...
