  • Lowe, David A.; Thorlacius, Larus (Springer Nature, 2018-01)
    Holographic theories representing black holes are expected to exhibit quantum chaos. We argue if the laws of quantum mechanics are expected to hold for observers inside such black holes, then such holographic theories must have a mean field approximation ...
  • Keränen, Ville; Sybesma, Watse; Szepietowski, Phillip; Thorlacius, Larus (Springer Nature, 2017-05)
    The 2+1 dimensional quantum Lifshitz model can be generalised to a class of higher dimensional free field theories that exhibit Lifshitz scaling. When the dynamical critical exponent equals the number of spatial dimensions, equal time correlation ...
  • Gudmundsson, Vidar; Abdulla, 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 ...
  • Brown, Adam R.; Gharibyan, Hrant; Streicher, Alexandre; Susskind, Leonard; Thorlacius, Larus; Zhao, Ying (American Physical Society (APS), 2018-12-28)
    The growth of the “size” of operators is an important diagnostic of quantum chaos. Susskind conjectured that the holographic dual of the size is proportional to the average radial component of the momentum of the particle created by the operator. Thus ...
  • Lowe, David A.; Thorlacius, Larus (Springer Nature, 2016-12)
    We explore a version of black hole complementarity, where an approximate semiclassical effective field theory for interior infalling degrees of freedom emerges holo-graphically from an exact evolution of exterior degrees of freedom. The infalling degrees ...
  • Ásgeirsson, Vilhjálmur; Bauer, Christoph A.; Grimme, Stefan (Royal Society of Chemistry (RSC), 2017)
    We introduce a fully stand-alone version of the Quantum Chemistry Electron Ionization Mass Spectra (QCEIMS) program [S. Grimme, Angew. Chem. Int. Ed., 2013, 52, 6306] allowing efficient simulations for molecules composed of elements with atomic numbers ...
  • Vlasov, Sergei M. (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-12)
    Nanomagnetic systems and transitions between magnetic states are currently an active topic of research. Spintronics is, in particular, a new branch of science and technology where spin degrees of freedom and spin currents are used in an analogous way ...
  • Szilva, A.; Thonig, D.; Bessarab, Pavel; Kvashnin, Y. O.; Rodrigues, D. C. M.; Cardias, R.; Pereiro, M.; Nordström, L.; Bergman, A.; Klautau, A. B.; Eriksson, O. (American Physical Society (APS), 2017-10-10)
    We show for a simple noncollinear configuration of the atomistic spins (in particular, where one spin is rotated by a finite angle in a ferromagnetic background) that the pairwise energy variation computed in terms of multiple-scattering formalism ...
  • Ricco, L. S.; Dessotti, F. A.; Shelykh, Ivan; Figueira, M. S.; Seridonio, A. C. (Springer Nature, 2018-02-12)
    We investigate theoretically thermal and electrical conductances for the system consisting of a quantum dot (QD) connected both to a pair of Majorana fermions residing at the edges of a Kitaev wire and two metallic leads. We demonstrate that both ...
