DISPERSION-RELATIONS AND THE NUCLEON POLARIZABILITY
Protons and neutrons polarizability dispersion relations meson polarizability
2014/12/23
Recent experimental results on the proton and neutron polarizabilities are examined from the point of view of backward dispersion relations. Results are found to be in reasonable agreement with the me...
On the Marriage of Chiral Perturbation Theory and Dispersion Relations
Dispersion relations chiral perturbation theory gw PI
2014/12/23
I describe the methodology for the use of dispersion relations in connection with chiral perturbation theory. The conditions for matching the two formalisms are given at $O(E^2)$ and $O(E^4)$. The two...
The techniques of dispersion relations match very well with those of effective field theory. I describe the techniques for using dispersion relations effectively, and give some pedagogical examples to...
Bose-Einstein condensation, fluctuations, and recurrence relations in statistical mechanics
Gas bose Einstein condensation partition function condensation
2014/12/20
We calculate certain features of Bose–Einstein condensation in the ideal gas by using recurrence relations for the partition function. The grand canonical ensemble gives inaccurate results for certain...
Generalized T-Q relations and the open spin-s XXZ chain with nondiagonal boundary terms

2012/6/21
We consider the open spin-s XXZ quantum spin chain with nondiagonal boundary terms. By exploiting certain functional relations at roots of unity, we derive a generalized form of T-Q relation involving...

Calculation of shear viscosity Green-Kubo relations
2011/7/21
The shear viscosity of a gluon gas is calculated using the Green-Kubo relation. Time correlations of the energy-momentum tensor in thermal equilibrium are extracted from microscopic simulations using ...
On the universal relations for the formfactors in 1D quantum liquids

2011/9/16
Abstract: For various one-dimensional quantum liquids in the framework of the Luttinger model (bosonization) we establish the relations between the coefficients before the power-law asymptotics of the...
Dispersion relations for circular single and double dusty plasma chains
Dispersion relations circular single and double dusty plasma chains
2011/8/5
Abstract: We derive dispersion relations for a system of identical particles confined in a two-dimensional annular harmonic well and which interact through a Yukawa potential, e.g., a dusty plasma rin...
What constitutive relations are inconsistent with quantum electromagnetism?

2011/9/1
Recent work by T. G. Philbin [1] has provided a Lagrangian theory that establishes a general method for the canonical quantization of the electromagnetic field in dispersive, lossy, linear dielectrics...

Abstract: We study the 1D extended Hubbard model with a weak repulsive short-range interaction in the non-half-filled band case, using non-perturbative Renormalization Group methods and Ward Identitie...
