Realizing Quantum Controlled Phase Flip through Cavity-QEDAug 05 2004We propose a scheme to realize quantum controlled phase flip (CPF) between two rare earth ions embedded in respective microsphere cavity via interacting with a single-photon pulse in sequence. The numerical simulations illuminate that the CPF gate between ... More

Period relations and special values of Rankin-Selberg $L$-functionsAug 26 2016This is a survey of recent work on values of Rankin-Selberg $L$-functions of pairs of cohomological automorphic representations that are {\it critical} in Deligne's sense. The base field is assumed to be a CM field. Deligne's conjecture is stated in the ... More

Real-Time Referring Expression Comprehension by Single-Stage Grounding NetworkDec 09 2018In this paper, we propose a novel end-to-end model, namely Single-Stage Grounding network (SSG), to localize the referent given a referring expression within an image. Different from previous multi-stage models which rely on object proposals or detected ... More

Constraints on Dark Matter Annihilation/Decay from the Isotropic Gamma-Ray BackgroundFeb 02 2016In this work we study the constraints on dark matter (DM) annihilation/decay from the Fermi-LAT Isotropic Gamma-Ray Background (IGRB) observation. We consider the contributions from both extragalactic and galactic DM components. For DM annihilation, the ... More

Probing the R-parity violating supersymmetric effects in the exclusive $c\to d/s\ellν_\ell$ decaysJul 06 2014A lot of branching ratios of the exclusive $c \to d/s\ell\nu_\ell$ ($\ell=e,\mu$) decays have been quite accurately measured by CLEO-c, BELLE, BABAR, BES(I,II,III), ALEPH and MARKIII collaborations. We probe the R-parity violating supersymmetric effects ... More
