Chiral symmetry and the parity-violating NN pi Yukawa coupling
Lagrange differential pv coupling constant the standard model
2014/12/22
We construct the complete SU(2) parity-violating (PV) π,N,Δ interaction Lagrangian with one derivative, and calculate the chiral corrections to the PV Yukawa NNπ coupling constant hπ through O(1/Λχ3) ...
Light Transport in Random Media with ${\cal PT}$-Symmetry
Light Transport Random Media ${\cal PT}$-Symmetry Optics
2012/5/29
The scattering properties of randomly layered optical media with ${\cal PT}$-symmetric index of refraction are studied using the transfer-matrix method. We find that the transmitance decays exponentia...
The utilization of time reversal symmetry in designing and implementing (quantum) optical experiments has become more and more frequent over the past years. We review the basic idea underlying time re...
Perturbation Theory for PT-Symmetric Sinusoidal Optical Lattices at the Symmetry-Breaking Threshold
PT-Symmetric Sinusoidal Optical the Symmetry-Breaking Threshold
2011/8/31
The PT symmetric potential V0[cos(2x/a)+i sin(2x/a)] has a completely real spectrum for ≤ 1, and begins to develop complex eigenvalues for > 1. At the
symmetry-breaking threshold = 1 some of...
Holographic Symmetry-Breaking Phases in AdS$_3$/CFT$_2$
Holographic Symmetry-Breaking Phases AdS$_3$/CFT$_2$
2010/12/21
In this note we study the symmetry-breaking phases of 3D gravity coupled to matter. In particular, we consider black holes with scalar hair as a model of symmetry-breaking phases of a strongly coupled...
An unusual form of symmetry known as E8 – which some physicists believe underlies a theory of everything – may have been spotted in a solid material for the first time. Physicists in Germany and the U...
