Magnetization and Magnetoresistance of CeRu2Al10 under High Magnetic Fields along c-Axis
CeRu2Al10 Kondo semiconductor pulsed high magnetic field
<
2010/11/24
We have studied the magnetization and magnetoresistance of CeRu2Al10 in the applied magnetic field H along the c-axis up to ∼ 55 T. The magnetization M at low temperatures shows an H-linear incr...
Potential for measurement of the tensor electric and magnetic polarizabilities of the deuteron in storage-ring experiments with polarized beams
Potential measurement of the tensor electric magnetic polarizabilities of the deuteron in storage-ring experiments polarized beams
<
2011/1/7
Measurement of the tensor electric and magnetic polarizabilities of the deuteron is of great
interest, especially in connection with the possibilities of COSY and GSI. These polarizabilities can be m...

Two-flavor chiral expansions provide a useful perturbative framework to study hadron properties.
Such expansions should exhibit marked improvement over the conventional three-flavor chiral
expansion...

Detection of spin injection into a double quantum dot: Violation of magnetic-field-inversion symmetry of nuclear polarization instabilities
Detection of spin injection double quantum dot: Violation nuclear polarization instabilities
<
2010/11/19
In mesoscopic systems with spin-orbit coupling, spin-injection into quantum dots at zero magnetic eld is expected under a wide range of conditions. However, up to now, a viable approach for experimen...
Gravitational Waves from the $r$-mode instability of neutron stars: effect of magnetic field
Gravitational Waves $r$-mode instability neutron stars: effect magnetic field

2010/12/20
Studies have shown that emission of gravitational waves drives an instability in the r-modes
of young rapidly rotating neutron stars carrying away most of the angular momentum through
gravitational ...
Electromagnetic Corrections in Staggered Chiral Perturbation Theory

<
2011/1/14
To reduce errors in light-quark mass determinations, it is now necessary to consider electromagnetic contributions to light-meson masses. Calculations using staggered quarks and quenched photons are c...

2010/10/27
We prove a large deviation principle for the expectation of macroscopic observables in quantum (and classical) Gibbs states. Our proof is based on Ruelle-Lanford functions [20, 34] and direct subaddit...
Linearly independent pure-state decomposition and quantum state discrimination

2010/11/8
We put the pure-state decomposition mathematical property of a mixed state to a physical test. We begin by characterizing all the possible decompositions of a rank-two mixed state by means of the comp...

In this Letter we study the effect of Pauli blocking on the Efimov states in a quantum Fermi
gas and illustrate that the universal Efimov potential is altered at large distances. We obtain the univer...
We explore the Franck-Condon physics in a single ion confined in a spin-dependent potential,
formed by the combination of a Paul trap and a gradient magnetic field. The correlation between
electroni...
