Discrete chaotic states of a Bose-Einstein condensate
Wenhua Hai, Shiguang Rong, Qianquan Zhu
We find the different spatial chaos in a one-dimensional attractive Bose-Einstein condensate interacting with a Gaussian-like laser barrier and perturbed by a weak optical lattice.…
Optical Monitoring of 3C 390.3 from 1995 to 2004 and Possible Periodicities in the Historical Light Curve
Jun Tao, Junhui Fan, Bochen Qian +1
We report V, R, and I band CCD photometry of the radio galaxy 3C 390.3 obtained with the 1.56-m telescope of the Shanghai Astronomical Observatory from March 1995 to August 2004. C…
Greybody Factors for Rotating Black Holes on Codimension-2 Branes
Songbai Chen, Bin Wang, Ru-Keng Su +1
We study the absorption probability and Hawking radiation of the scalar field in the rotating black holes on codimension-2 branes. We find that finite brane tension modifies the st…
Reconstructing the properties of dark energy from recent observations
Puxun Wu, Hongwei Yu
We explore the properties of dark energy from recent observational data, including the Gold Sne Ia, the baryonic acoustic oscillation peak from SDSS, the CMB shift parameter from W…
Hawking radiation in a Rotating Kaluza-Klein Black Hole with Squashed Horizons
Songbai Chen, Bin Wang, Ru-Keng Su
We explore the signature of the extra dimension in the Hawking radiation in a rotating Kaluza-Klein black hole with squashed horizons. Comparing with the spherical case, we find th…
Entropy of the Schwarzschild-de Sitter Black Hole due to arbitrary spin fields in different Coordinates
Chikun Ding, Jiliang Jing
By using the Newman-Penrose formalism and the improved thin-layer ``brick wall'' approach, the statistical-mechanical entropies of the Schwarzschild-de Sitter black hole arising fr…
Do static atoms outside a Schwarzschild black hole spontaneously excite?
Hongwei Yu, Wenting Zhou
The spontaneous excitation of a two-level atom held static outside a four dimensional Schwarzschild black hole and in interaction with a massless scalar field in the Boulware, Unru…
Relationship between Hawking radiation from black holes and spontaneous excitation of atoms
Hongwei Yu, Wenting Zhou
Using the formalism that separates the contributions of vacuum fluctuations and radiation reaction to the rate of change of the mean atomic energy, we show that a two-level atom in…
Quantum theory for spatial motion of polaritons in inhomogeneous fields
Lan Zhou, Jing Lu, D. L. Zhou +1
Polaritons are the collective excitations of many atoms dressed by resonant photons, which can be used to explain the slow light propagation with the mechanism of electromagnetical…
The Unruh effect and entanglement generation for accelerated atoms near a reflecting boundary
Jialin Zhang, Hongwei Yu
We study, in the framework of open systems, the entanglement generation of two independent uniformly accelerated atoms in interaction with the vacuum fluctuations of massless scala…
Stabilities of one-dimensional stationary states of Bose-Einstein condensates
Wenhua Hai, Guishu Chong, Jianwen Song
We explore the dynamical stabilities of a quasi-one dimensional (1D) Bose-Einstein condensate (BEC) consisting of fixed atoms with time-independent external potential. For the…
Stability and exact multiplicity of periodic solutions of Duffing equations with cubic nonlinearities
Hongbin Chen, Yi Li
We study the stability and exact multiplicity of periodic solutions of the Duffing equation with cubic nonlinearities. We obtain sharp bounds for h such that the equation has exact…
Rate of Decay of Stable Periodic Solutions of Duffing Equations
Hongbin Chen, Yi Li
In this paper, we consider the second-order equations of Duffing type. Bounds for the derivative of the restoring force are given that ensure the existence and uniqueness of a peri…
Wave dynamics of a six-dimensional black hole localized on a tensional three-brane
Songbai Chen, Bin Wang, Ru-Keng Su
We study the quasinormal modes and the late-time tail behavior of scalar perturbation in the background of a black hole localized on a tensional three-brane in a world with two lar…
Radio variability properties for radio sources
J. H. Fan, Y. Liu, Y. H. Yuan
In this paper, we used the database of the university of Michigan Radio Astronomy Observatory (UMRAO) at three (4.8 GHz, 8.0 GHZ, and 14.5 GHz) radio frequency to analyze the radio…
Influence of Lorentz violation on Dirac quasinormal modes in the Schwarzschild black hole spacetime
Songbai Chen, Bin Wang, Rukeng Su
Using the third-order WKB approximation and monodromy methods, we investigate the influence of Lorentz violating coefficient (associated with a special axial-vector field…
Fulling-Davies-Unruh effect and spontaneous excitation of an accelerated atom interacting with a quantum scalar field
Zhiying Zhu, Hongwei Yu
We investigate, from the point of view of a coaccelerated frame, the spontaneous excitation of a uniformly accelerated two-level atom interacting with a scalar field in a thermal s…
Spontaneous excitation of an accelerated multilevel atom in dipole coupling to the derivative of a scalar field
Yunfeng Zhu, Hongwei Yu
We study the spontaneous excitation of an accelerated multilevel atom in dipole coupling to the derivative of a massless quantum scalar field and separately calculate the contribut…
