We use the outer gap model to explain the spectrum and the energy dependent light curves of the X-ray and soft gamma-ray radiations of the spin-down powered pulsar PSR B1509-58. In…
An Analytic Theory for the Orbits of Circumbinary Planets
Gene C. K. Leung, Man Hoi Lee
Three transiting circumbinary planets (Kepler-16 b, Kepler-34 b, and Kepler-35 b) have recently been discovered from photometric data taken by the Kepler spacecraft. Their orbits a…
Forced generation of simple and double emulsions in all-aqueous system
Alban Sauret, Ho Cheung Shum
We report an easy-to-implement method that allows the direct generation of water-in-water (w/w) single emulsions. The method relies on direct perturbation of the pressure that driv…
Formation and local symmetry of Holstein polaron in t-J model
Han Ma, T. K. Lee, Yan Chen
The formation and local symmetry of spin-lattice polaron has been investigated semiclassically in the planar Holstein t-J-like models within the exact diagonalization method. Due t…
Majorana Fermion Induced Non-local Current Correlations in Spin-orbit Coupled Superconducting Wires
Jie Liu, Fu-Chun Zhang, K. T. Law
Recent observation of zero bias conductance peaks in semiconductor wire/superconductor heterostructures has generated great interest, and there is a hot debate on whether the obser…
Efficiency improvement of the frequency-domain BEM for rapid transient elastodynamic analysis
Jinyou Xiao, Wenjing Ye, Lihua Wen
The frequency-domain fast boundary element method (BEM) combined with the exponential window technique leads to an efficient yet simple method for elastodynamic analysis. In this p…
Efficiency and Its Bounds for a Quantum Einstein Engine at Maximum Power
H. Yan, Hao Guo
We study a quantum thermal engine model for which the heat transfer law is determined by Einstein's theory of radiation. The working substance of the quantum engine is assumed to b…
Efficiency and Its Bounds for Thermal Engines at Maximum Power using a Newton's Law of Cooling
H. Yan, Hao Guo
We study a thermal engine model for which Newton's cooling law is obeyed during heat transfer processes. The thermal efficiency and its bounds at maximum output power are derived a…
Photonic simulation of topological excitations in metamaterials
Wei Tan, Yong Sun, Hong Chen +1
Condensed matter systems with topological order and metamaterials with left-handed chirality have attracted recently extensive interests in the fields of physics and optics. So far…
Multipolar Planetary Nebulae: Not as Geometrically Diversified as Thought
Sze-Ning Chong, Sun Kwok, Hiroshi Imai +2
Planetary nebulae (PNe) have diverse morphological shapes, including point-symmetric and multipolar structures. Many PNe also have complicated internal structures such as torus, lo…
Improved Measurement of Electron Antineutrino Disappearance at Daya Bay
Daya Bay Collaboration, F. P. An, Q. An +227
We report an improved measurement of the neutrino mixing angle from the Daya Bay Reactor Neutrino Experiment. We exclude a zero value for with a significan…
Nonparametric estimate of spectral density functions of sample covariance matrices: A first step
Bing-Yi Jing, Guangming Pan, Qi-Man Shao +1
The density function of the limiting spectral distribution of general sample covariance matrices is usually unknown. We propose to use kernel estimators which are proved to be cons…
