Approximate Treatment of Hermitian Effective Interactions and a Bound on the Error
The Hermitian effective interaction can be well-approximated by
(R+R^dagger)/2 if the eigenvalues of omega^dagger omega are small or
state-independent(degenerate), where R is the standard non-Hermitian effective
interaction and omega maps the model-space states onto the excluded space. An
error bound on this approximation is given.Comment: 13 page
Ground-state properties of one-dimensional anyon gases
We investigate the ground state of the one-dimensional interacting anyonic
system based on the exact Bethe ansatz solution for arbitrary coupling constant
() and statistics parameter (). It
is shown that the density of state in quasi-momentum space and the ground
state energy are determined by the renormalized coupling constant . The
effect induced by the statistics parameter exhibits in the momentum
distribution in two aspects: Besides the effect of renormalized coupling, the
anyonic statistics results in the nonsymmetric momentum distribution when the
statistics parameter deviates from 0 (Bose statistics) and
(Fermi statistics) for any coupling constant . The momentum distribution
evolves from a Bose distribution to a Fermi one as varies from 0 to
. The asymmetric momentum distribution comes from the contribution of the
imaginary part of the non-diagonal element of reduced density matrix, which is
an odd function of . The peak at positive momentum will shift to
negative momentum if is negative.Comment: 6 pages, 5 figures, published version in Phys. Rev.
Density-functional theory for 1D harmonically trapped Bose-Fermi mixture
We present a density-functional theory for the one dimensional harmonically
trapped Bose-Fermi mixture with repulsive contact interactions. The ground
state density distribution of each component is obtained by solving the
Kohn-Sham equations numerically based on the Local Density Approximation and
the exact solution for the homogeneous system given by Bethe ansatz method. It
is shown that for strong enough interaction, a considerable amount of fermions
are repelled out of the central region of the trap, exhibiting partial phase
separation of Bose and Fermi components. Oscillations emerge in the Bose
density curves reflecting the strong correlation with Fermions. For infinite
strong interaction, the ground state energy of the mixture and the total
density are consistent with the scenario that all atoms in the mixture are
fully fermionized.Comment: 10 pages, 8 figure
Numerical Simulation of Magnetic Interactions in Polycrystalline YFeO3
The magnetic behavior of polycrystalline yttrium orthoferrite was studied
from the experimental and theoretical points of view. Magnetization
measurements up to 170 kOe were carried out on a single-phase YFeO3 sample
synthesized from heterobimetallic alkoxides. The complex interplay between
weak-ferromagnetic and antiferromagnetic interactions, observed in the
experimental M(H) curves, was successfully simulated by locally minimizing the
magnetic energy of two interacting Fe sublattices. The resulting values of
exchange field (H_E = 5590 kOe), anisotropy field (H_A = 0.5 kOe) and
Dzyaloshinsky-Moriya antisymmetric field (H_D = 149 kOe) are in good agreement
with previous reports on this system.Comment: 26 pages, 9 figure
Unquenching effects on the coefficients of the L\"uscher-Weisz action
The effects of unquenching on the perturbative improvement coefficients in
the Symanzik action are computed within the framework of L\"uscher-Weisz
on-shell improvement. We find that the effects of quark loops are surprisingly
large, and their omission may well explain the scaling violations observed in
some unquenched studies.Comment: 7 pages, 5 figures, uses revtex4; version to appear in Phys.Rev.
Phenomenological theory of a scalar electronic order: application to skutterudite PrFe4P12
By phenomenological Landau analysis, it is shown that a scalar order
parameter with the point-group symmetry explains most properties
associated with the phase transition in PrFeP at 6.5 K. The
scalar-order model reproduces magnetic and elastic properties in
PrFeP consistently such as (i) the anomaly of the magnetic
susceptibility and elastic constant at the transition temperature, (ii)
anisotropy of the magnetic susceptibility in the presence of uniaxial pressure,
and (iii) the anomaly in the elastic constant in magnetic field. An Ehrenfest
relation is derived which relates the anomaly of the magnetic susceptibility to
that of the elastic constant at the transition.Comment: 16 pages, 9 figure
