  • Gudmundsson, Vidar; Manolescu, Andrei; Nemnes, George Alexandru; Sitek, Anna; Erlingsson, Sigurður Ingi; Rosdahl, Tómas (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 ...
  • Gudmundsson, Vidar; Abdullah, Nzar Rauf; Sitek, Anna; Goan, Hsi-Sheng; Tang, Chi-Shung; Manolescu, Andrei (Wiley-Blackwell, 2017-12-07)
    We show that a Rabi-splitting of the states of strongly interacting electrons in parallel quantum dots embedded in a short quantum wire placed in a photon cavity can be produced by either the para- or the dia-magnetic electron-photon interactions ...
  • Sitek, Anna; Urbaneja Torres, Miguel; Torfason, Kristinn; Gudmundsson, Vidar; Bertoni, Andrea; Manolescu, Andrei (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 ...

    Two familial forms of colorectal cancer (CRC), Lynch syndrome (LS) and familial adenomatous polyposis (FAP), are caused by rare mutations in DNA mismatch repair genes (MLH1, MSH2, MSH6, PMS2) and the genes APC and MUTYH, respectively. No information ...
  • Sitek, Anna; Ţolea, Mugurel; Niţă, Marian; Serra, Llorenç; Gudmundsson, Vidar; Manolescu, Andrei (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., ...
  • Visan, Camelia; Anghel, D. V.; Nemnes, George Alexandru; Manolescu, Andrei (IOP Publishing, 2016-08)
    The hybrid graphene - hexagonal boron nitride (G-hBN) systems offer new routes in the design of nanoscale electronic devices. Using ab initio density functional theory calculations we investigate the dynamics of zig-zag nanoribbons a few interatomic ...
  • Torfason, Kristinn; Valfells, Agust; Manolescu, Andrei (ArXiv, 2016-08)
    High resolution molecular dynamics simulations with full Coulomb interactions of electrons are used to investigate field emission from a prolate spheroidal tip. The space charge limited current is several times lower than the current calculated with ...
  • Abdullah, Nzar Rauf; Tang, Chi-Shung; Manolescu, Andrei; Gudmundsson, Vidar (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 ...

    To find sequence variants affecting prostate cancer (PCA) susceptibility in an unscreened Romanian population we use a genome‐wide association study (GWAS). The study population included 990 unrelated pathologically confirmed PCA cases and 1034 male ...
  • Jinga, Viorel; Csiki, Irma Eva; Manolescu, Andrei; Iordache, Paul; Mates, Ioan Nicolae; Radavoi, Daniel; Rascu, Stefan; Badescu, Daniel; Badea, Paula; Mates, Dana (Wiley, 2016-01-15)
    Prostate cancer is the third‐most common form of cancer in men in Romania. The Romanian unscreened population represents a good sample to study common genetic risk variants. However, a comprehensive analysis has not been conducted yet. Here, we report ...
  • Stanescu, Tudor D; Sitek, Anna; Manolescu, Andrei (Beilstein Institut, 2018-05-22)
    We consider core–shell nanowires with prismatic geometry contacted with two or more superconductors in the presence of a magnetic field applied parallel to the wire. In this geometry, the lowest energy states are localized on the outer edges of the ...
  • Capps, Jeremy; Marinescu, D. C.; Manolescu, Andrei (American Physical Society (APS), 2016-02-09)
    We demonstrate that a spin-dependent Seebeck effect can be detected in quantum wells with zinc-blend structure with equal Rashba-Dresselhaus spin-orbit couplings. This theory is based on the establishment of an itinerant antiferromagnetic state, a low ...
  • Erlingsson, Sigurður Ingi; Bardarson, Jens H; Manolescu, Andrei (Beilstein Institut, 2018-04-12)
    In this paper we consider charge current generated by maintaining a temperature difference over a nanowire at zero voltage bias. For topological insulator nanowires in a perpendicular magnetic field the current can change sign as the temperature of one ...
