script O sign(αs2) QCD corrections to the electroproduction of hadrons with high transverse momentum
(American Physical Society, 2005-02)
We compute the order αs2 corrections to the one particle inclusive electroproduction cross section of hadrons with nonvanishing transverse momentum. We perform the full calculation analytically, and obtain the expression ...
Holographic superconductor with disorder
(American Physical Society, 2014-05)
We study the effects of disorder on a holographic superconductor by introducing a random chemical potential on the boundary. We consider various realizations of disorder and find that the critical temperature for ...
Discriminating between SUSY and non-SUSY Higgs sectors through the ratio H→ bb¯ / H→ τ+τ- with a 125 GeV Higgs boson
(Springer, 2016-05)
It is still an open question whether the new scalar particle discovered at the LHC with a mass of 125 GeV is the SM Higgs boson or belongs to models of new physics with an extended Higgs sector, as the MSSM or 2HDM. The ...
Spin polarization in the Hubbard model with Rashba spin-orbit coupling on a ladder
(American Physical Society, 2013-07)
The competition between on-site Coulomb repulsion and Rashba spin-orbit coupling (RSOC) is studied on two-leg ladders by numerical techniques. By studying persistent currents in closed rings by exact diagonalization, it ...
Generation of chiral solitons in antiferromagnetic chains by a quantum quench
(American Physical Society, 2013-11)
We analyze the time evolution of a magnetic excitation in a spin-12 antiferromagnetic Heisenberg chain after a quantum quench. By a proper modulation of the magnetic exchange coupling, we prepare a static soliton of total ...
Exact solution for three particles interacting via zero-range potentials
(American Physical Society, 2006-12)
Exact solutions for three identical bosons interacting via zero-range s -wave potentials are derived. The solutions are contour integrals over a product of hyperradial Bessel functions times angular functions weighted by ...
Spin-orbit effects in nanowire-based wurtzite semiconductor quantum dots
(American Physical Society, 2013-07-03)
We study the effect of the Dresselhaus spin-orbit interaction on the electronic states and spin relaxation rates of cylindrical quantum dots defined on quantum wires having wurtzite lattice structure. The linear and cubic ...
Spin-spin correlations between two Kondo impurities coupled to an open Hubbard chain
(American Physical Society, 2013-02)
In order to study the interplay between Kondo and Ruderman-Kittel-Kasuya-Yosida interaction, we calculate the spin-spin correlation functions between two Kondo impurities coupled to different sites of a half-filled open ...
Soft-gluon resummation for pseudoscalar Higgs boson production at hadron colliders
(Elsevier Science, 2008-01)
We compute the threshold-resummed cross section for pseudo-scalar MSSM Higgs boson production by gluon fusion at hadron colliders. The calculation is performed at next-to-next-to leading logarithmic accuracy. We present ...
