An overview of the Daya Bay Reactor Neutrino Experiment
The Daya Bay Reactor Neutrino Experiment discovered an unexpectedly large
neutrino oscillation related to the mixing angle in 2012. This
finding paved the way to the next generation of neutrino oscillation
experiments. In this article, we review the history, featured design, and
scientific results of Daya Bay. Prospects of the experiment are also described.Comment: 18 pages, 5 figures. An overview to appear in the Special Issue on

Effect of dissipative forces on the theory of a single-atom microlaser
We describe a one-atom microlaser involving Poissonian input of atoms with a
fixed flight time through an optical resonator. The influence of the cavity
reservoir during the interactions of successive individual atoms with the
cavity field is included in the analysis. The atomic decay is also considered
as it is nonnegligible in the optical regime. During the random intervals of
absence of any atom in the cavity, the field evolves under its own dynamics. We
discuss the steady-state characteristics of the cavity field. Away from laser
threshold, the field can be nonclassical in nature.Comment: 9 pages in LaTex; 3 PS figure
Current algebra based effective chiral theory of mesons and a new EW theory
A current algebra based effective chiral theory of pseudoscalar, vector,
axial-vector mesons is reviewed. A new mechanism generating the masses and
guage fixing terms of gauge boson is revealed from this effective theory. A EW
theory without Higgs is proposed. The masses and gauge fixing terms of W and Z
are dynamically generated. Three heavy scalar fields are dynamically generated
too. They are ghosts.Comment: 4 pages, talk presented at conference of QCD and hadronic physics,

Functional Equations and Fourier Analysis
By exploring the relations among functional equations, harmonic analysis and
representation theory, we give a unified and very accessible approach to solve
three important functional equations -- the d'Alembert equation, the Wilson
equation, and the d'Alembert long equation, on compact groups.Comment: 8 pages, to appear in CM
