Spin-orbit interaction determined by antilocalization in an InSb quantum well
(American Physical Society, 2010-02-02)
The magnetoresistance at temperatures below 20 K in an n-InSb/In(0.85)Al(0.15)Sb two-dimensional electron system is studied and described in terms of antilocalization due to quantum interference under strong spin-orbit ...
Leptonic CP violation search and the ambiguity of delta m(31)(2)
(American Physical Society, 2006-03)
We consider a search for the CP-violating angle delta(CP) in long baseline neutrino oscillation experiments. We show that the subleading delta(CP)-dependent terms in the nu(mu)->nu(e) oscillation probability can be easily ...
Thermal production of axions in the Earth
(American Physical Society, 2009-05)
We estimate the production rate of axion-type particles in the core of the Earth, at a temperature T approximate to 5000 K. We constrain thermal geo-axion emission by demanding a core-cooling rate less than O(100) K/Gyr, ...
Time-resolved differential transmission in MOVPE-grown ferromagnetic InMnAs
(American Physical Society, 2012-03-27)
We measured time-resolved differential transmission in InMnAs for different pump/probe schemes as a function of temperature, laser fluence, and external magnetic field. We observed tunability of the carrier relaxation time. ...
Electronic and quantum phase coherence properties of bismuth thin films
(AIP Publishing, 2012-06)
We present a method to deposit bulk-like Bi films by thermal evaporation and study the electrical, quantum coherence, and physical properties. A two stage growth procedure was found to optimize the film properties, with ...
Transient pulses from exploding primordial black holes as a signature of an extra dimension
(Iop Publishing Ltd, 2008-11-01)
Reaction-controlled diffusion: Monte Carlo simulations
(American Physical Society, 2003-10)
We study the coupled two-species nonequilibrium reaction-controlled diffusion model introduced by Trimper [Phys. Rev. E 62, 6071 (2000)] by means of detailed Monte Carlo simulations in one and two dimensions. Particles of ...
Determination of the Axial-Vector Weak Coupling Constant with Ultracold Neutrons
(American Physical Society, 2010-10-29)
A precise measurement of the neutron decay beta asymmetry A(0) has been carried out using polarized ultracold neutrons from the pulsed spallation ultracold neutron source at the Los Alamos Neutron Science Center. Combining ...
Percolation-enhanced supersolids in the extended Bose-Hubbard model
(American Physical Society, 2012-01-04)
We theoretically study the stability of lattice supersolid states in the extended Bose-Hubbard model with bounded spatial disorder. We construct a disorder mean-field theory and compare with quantum Monte Carlo calculations. ...
Pair contact process with diffusion: Failure of master equation field theory
(American Physical Society, 2004-11)
We demonstrate that the "microscopic" field theory representation, directly derived from the corresponding master equation, fails to adequately capture the continuous nonequilibrium phase transition of the pair contact ...
