We show that its reversibility ... More

Decoupling of valence nucleons in configuration-interaction shell model approachAug 30 2010The unusual ratio of the neutron and proton transition matrix elements, $M_n/M_p$, may indicate the exotic feature of decoupled neutron and proton density distributions. In this contribution we show that these transition matrix elements are not the same ... More

Probing anomalous top quark interactions at the Fermilab Tevatron ColliderJun 18 1998Jul 29 1998We study the effects of dimension-six operators contributing to the $gt\bar t$ vertex in top quark pair production at the Tevatron collider. We derive both the limits from Run 1 data and the potential bounds from future runs (Run 2 and 3). Although the ... More

Double resonance of Raman transitions in a degenerate Fermi gasMar 01 2017Mar 31 2017We measure momentum-resolved Raman spectra of a spin-polarized degenerate Fermi gas of $^{173}$Yb atoms for a wide range of magnetic fields, where the atoms are irradiated by a pair of counterpropagating Raman laser beams as in the conventional spin-orbit ...

FeynmanPAQS: A Graphical Interface Program for Photonic Analog Quantum ComputingOct 04 2018We present a user-friendly software for photonic analog quantum computing with an installable MATLAB package and the graphical user interface (GUI) that allows for convenient operation without requiring programming skills. Arbitrary Hamiltonians can be ... More

NMSSM with generalized deflected mirage mediationApr 19 2018May 14 2019We propose to generate a realistic soft SUSY breaking spectrum for Next-to-Minimal Supersymmetric Standard Model (NMSSM) with a generalized deflected mirage mediation scenario, in which additional Yukawa and gauge mediation contributions are included ...

Limit of zT enhancement in rock-salt structured chalcogenides by band convergence?Jun 28 2016Rock-salt structured chalcogenides, such as PbTe, PbSe, and SnTe, are the top candidates for mid-temperature thermoelectric applications, and their p-type thermoelectric efficiencies can be enhanced via aligning the valence bands. Here, we provided comprehensive ... More

Adaptive Spatial Modulation for Visible Light Communications with an Arbitrary Number of TransmittersJul 26 2018As a power and bandwidth efficient modulation scheme, the optical spatial modulation (SM) technique has recently drawn increased attention in the field of visible light communications (VLC). To guarantee the number of bits mapped by the transmitter's ... More

Physical-layer Security for Indoor Visible Light Communications: Secrecy Capacity AnalysisJul 26 2018This paper investigates the physical-layer security for an indoor visible light communication (VLC) network consisting of a transmitter, a legitimate receiver and an eavesdropper. Both the main channel and the wiretapping channel have nonnegative inputs, ... More
