Metallic thin films on stepped surfaces: lateral scattering of quantum well states
(IOP Publishing, 2014-12-10)
Quantum well states of Ag films grown on stepped Au(111) surfaces are shown to undergo lateral scattering, in analogy with surface states of vicinal Ag(111). Applying angle resolved photoemission spectroscopy we observe ...
Digital Quantum Simulation of Spin Models with Circuit Quantum Electrodynamics
(American Physical Society, 2015-06-17)
Systems of interacting quantum spins show a rich spectrum of quantum phases and display interesting many-body dynamics. Computing characteristics of even small systems on conventional computers poses significant challenges. ...
Dual-path methods for propagating quantum microwaves
(IOP Publishing, 2014-01)
We study quantum state tomography, entanglement detection and channel noise reconstruction of propagating quantum microwaves via dual-path methods. The presented schemes make use of the following key elements: propagation ...
Quantum simulations of relativistic quantum physics in circuit QED
(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 ...
Optimally robust shortcuts to population inversion in two-level quantum systems
(IOP Publishing LTD, 2012-09-21)
We examine the stability versus different types of perturbations of recently proposed shortcuts to adiabaticity to speed up the population inversion of a two-level quantum system. We find the optimally robust processes by ...
Fitting BICEP2 with defects, primordial gravitational waves and dust
(IOP Publishing, 2015)
In this work we discuss the possibility of cosmic defects being responsible for the B-mode signal measured by the BICEP2 collaboration. We also allow for the presence of other cosmological sources of B-modes such as ...
Interface electronics for an RF resonance-based displacement sensor
(IOP Publishing LTD, 2013)
We propose, design, and test an electronic interface for a new standalone, affordable and compact displacement transducer based on resonant cavities. The operation of the interface establishes a self-resonance in the ...
Double layers in gravity theories
(IOP Publishing, 2015)
Gravitational double layers, unlike their classical electromagnetic counterparts, are thought to be forbidden in gravity theories. It has been recently shown, however, that they are feasible in, for instance, gravity ...
A chemically inert Rashba split interface electronic structure of C-60, FeOEP and PTCDA on BiAg2/Ag(111) substrates
(IOP Publishing, 2014-04-04)
The fields of organic electronics and spintronics have the potential to revolutionize the electronics industry. Finding the right materials that can retain their electrical and spin properties when combined is a technological ...
Hartle's model within the general theory of perturbatiye matchings: the change in mass
(IOP Publishing, 2015)
Hartle's model provides the most widely used analytic framework to describe isolated compact bodies rotating slowly in equilibrium up to second order in perturbations in the context of General Relativity. Apart from some ...
