On the refined Gan-Gross-Prasad conjecture for cusp forms of GSp(4)
We prove a conjectural formula relating the Bessel period of certain
automorphic forms on to a central -value. This formula is
proposed by Liu \cite{liu} as the refined Gan-Gross-Prasad conjecture for the
groups (\SO(5), \SO(2)). The conjecture has been previously proved for
certain automorphic forms on from lifts. In this paper, we
extend the formula to Siegel modular forms of \Sp_4(\bZ).Comment: fix constant 1/8; discuss the global L-function. arXiv admin note:

Bhargava Integer Cubes and Weyl Group Multiple Dirichlet Series
We investigate the Shintani zeta functions associated to the prehomogeneous
spaces, the example under consideration is the set of
integer cubes. We show that there are three relative invariants under a certain
parabolic group action, they all have arithmetic nature and completely
determine the equivalence classes. We show that the associated Shintani zeta
function coincides with the Weyl group multiple Dirichlet series.
Finally, we show that the set of semi-stable integer orbits maps finitely and
surjectively to a certain moduli space
Bhargava's composition law and Waldspurger's central value theorem
We reprove a Waldspurger's formula which relates the toric periods and the
central values of L-functions of GL2. Our technique, different from the
original theta-correspondence approach and the more recent relative trace
formula, relies on the exploit of distributions defined on prehomogeneous
vector spaces.Comment: arXiv admin note: text overlap with arXiv:1311.213
Landau levels of cold dense quark matter in a strong magnetic field
The occupied Landau levels of strange quark matter are investigated in the
framework of the SU(3) NJL model with a conventional coupling and a
magnetic-field dependent coupling respectively. At lower density, the Landau
levels are mainly dominated by u and d quarks. Threshold values of the chemical
potential for the s quark onset are shown in the - plane. The
magnetic-field-dependent running coupling can broaden the region of
three-flavor matter by decreasing the dynamical masses of quarks. Before
the onset of quarks, the Landau level number of light quarks is directly
dependent on the magnetic field strength by a simple inverse proportional
relation with G,
which is approximately 2 times of quarks at a common chemical
potential. When the magnetic field increases up to , almost all three
flavors are lying in the lowest Landau level.Comment: 8 pages, 6 figures, 1 table, arXiv admin note: text overlap with

Simulating the Chiral Magnetic Wave in a Box System
The chiral magnetic wave from the interplay between the chiral magnetic
effect and the chiral separation effect is simulated in a box system with the
periodic boundary condition based on the chiral kinetic equations of motion.
Simulation results are compared with available limits from theoretical
derivations, and effects of the temperature, the magnetic field, and the
specific shear viscosity on the key properties of the chiral magnetic wave are
discussed. Our study serves as a baseline for further simulations of chiral
anomalies in relativistic heavy-ion collisions.Comment: 7 pages, 5 figure
Variational principle for weighted topological pressure
Let be a factor map, where and are topological
dynamical systems. Let with and
, and . The -weighted topological pressure of
, denoted by , is defined by resembling the Hausdorff
dimension of subsets of self-affine carpets. We prove the following variational
principle:
where the supremum is taken over the -invariant measures on . It not only
generalizes the variational principle of classical topological pressure, but
also provides a topological extension of dimension theory of invariant sets and
measures on the torus under affine diagonal endomorphisms. A higher dimensional
version of the result is also established
Quantum Signature Protocol without the Trusted Third Party
An authentic digital signature scheme based on the correlation of
Greenberger-Horne-Zeilinger (GHZ) states was presented. In this scheme, by
performing a local unitary operation on the third particles of each GHZ
triplet, Alice can encode message M and get its signature S. Bob performs CNOT
operation on the combined GHZ triplets can recovery the message M and directly
authenticates Alice's signature S. Our scheme was designed to use quantum
secret key to guaranteed unconditional security, as well as use quantum
fingerprinting to avoid trick attacks and reduce communication complexity.Comment: 5 page
Simulating chiral anomalies with spin dynamics
Considering that the chiral kinetic equations of motion (CEOM) can be derived
from the spin kinetic equations of motion (SEOM) for massless particles with
approximations, we simulate the chiral anomalies by using the latter in a box
system with the periodic boundary condition under a uniform external magnetic
field. We found that the chiral magnetic effect is weaker while the damping of
the chiral magnetic wave is stronger from the SEOM compared with that from the
CEOM. In addition, effects induced by chiral anomalies from the SEOM are less
sensitive to the decay of the magnetic field than from the CEOM due to the spin
relaxation process.Comment: 6 pages, 6 figure
Anisotropic Variable Hardy-Lorentz Spaces and Their Real Interpolation
Let be a variable exponent function
satisfying the globally log-H\"{o}lder continuous condition,
and be a general expansive matrix on . In this article, the
authors first introduce the anisotropic variable Hardy-Lorentz space
associated with , via the radial grand
maximal function, and then establish its radial or non-tangential maximal
function characterizations. Moreover, the authors also obtain characterizations
of , respectively, in terms of the atom and the
Lusin area function. As an application, the authors prove that the anisotropic
variable Hardy-Lorentz space severs as the
intermediate space between the anisotropic variable Hardy space
and the space via the
real interpolation. This, together with a special case of the real
interpolation theorem of H. Kempka and J. Vyb\'iral on the variable Lorentz
space, further implies the coincidence between
and the variable Lorentz space when
