Quantum simulations of relativistic quantum physics in circuit QED
Simón Pedernales, Julen Jon; Di Candia, Roberto; Ballester, D.; Solano Villanueva, Enrique Leónidas
(IOP Publishing, 2013-06)
We present a scheme for simulating relativistic quantum physics in circuit quantum electrodynamics. By using three classical microwave drives, we show that a superconducting qubit strongly coupled to a resonator field mode ... -
Real-Time Dynamics in U(1) Lattice Gauge Theories with Tensor Networks
Pichler, T.; Dalmonte, M.; Rico Ortega, Enrique; Zoller, P.; Montangero, S. (American Physical Society, 2016-03-03)
Tensor network algorithms provide a suitable route for tackling real-time-dependent problems in lattice gauge theories, enabling the investigation of out-of-equilibrium dynamics. We analyze a U(1) lattice gauge theory in ... -
Relativistic force between fast electrons and planar targets
(IOP Publishing, 2014-07-30)The full retarded electromagnetic force experienced by swift electrons moving parallel to planar boundaries is revisited, for both metallic and dielectric targets, with special emphasis on the consequences in electron ... -
Response of the topological surface state to surface disorder in TlBiSe2
(IOP Publishing, 2015-02-24)Through a combination of experimental techniques we show that the topmost layer of the topological insulator TlBiSe2 as prepared by cleavage is formed by irregularly shaped Tl islands at cryogenic temperatures and by mobile ... -
STM study on the self-assembly of oligothiophene-based organic semiconductors
(Beilstein Institut, 2011-11)The self-assembly properties of a series of functionalized regioregular oligo(3-alkylthiophenes) were investigated by using scanning tunneling microscopy (STM) at the liquid-solid interface under ambient conditions. The ... -
Subdiffusion of nonlinear waves in quasiperiodic potentials
(IOP Publishing, 2012-10-23)We study the time evolution of wave packets in one-dimensional quasiperiodic lattices which localize linear waves. Nonlinearity (related to two-body interactions) has a destructive effect on localization, as observed ... -
The center of mass and center of charge of the electron
(IOP Publishing, 2015)The goal of this contribution is to show that the hypothesis that the center of mass(CM) and the center of charge(CC) of a classical electron are two different points is only compatible with a relativistic description. The ... -
The effects of disorder in dimerized quantum magnets in mean field approximations
(IOP Publishing LTD, 2012-11-07)We study theoretically the effects of disorder on Bose-Einstein condensates (BEC) of bosonic triplon quasiparticles in doped dimerized quantum magnets. The condensation occurs in a magnetic field, where the concentration ... -
Unconventional spin texture of a topologically nontrivial semimetal Sb(110)
Stróżecka, A.; Eiguren Goyenechea, Asier; Bianchi, M.; Guan, D.; Voetmann, C. H.; Bao, S.; Hofmann, Ph.; Pascual Chico, José Ignacio (IOP Publishing LTD, 2012-10-17)
The surfaces of antimony are characterized by the presence of spin-split states within the projected bulk band gap and the Fermi contour is thus expected to exhibit a spin texture. Using spin-resolved density functional ... -
von Neumann spin measurements with Rashba fields
(IOP Publishing, 2014-01-10)We show that dynamics in the spin-orbit coupling field simulate the von Neumann measurement of a particle spin. We demonstrate how the measurement influences the spin and coordinate evolution of a particle by comparing two ...
