quantum dynamics of integrable spin chains
... essentially ergodic. This should mean that integrable quantum spin chains are not physical systems, that is they are not well posed models of statistical mechanics. This is at least a controversial idea. It is a certain fact that spin chains, as one dimensional models of magnetic alloys, are very in ...

Feynman Diagrams in Quantum Mechanics
... (edges). There are two types of vertices in these diagrams – internal and external vertices. Internal vertices in this case have three lines, corresponding to the perturbation x3 , and are labeled by a parameter t; each internal vertex has a different parameter. External vertices have a single line, ...

On the Stability of Classical Orbits of the Hydrogen Ground State in
... Abstract: De la Peña 1980 and Puthoff 1987 show that circular orbits in the hydrogen problem of Stochastic Electrodynamics connect to a stable situation, where the electron neither collapses onto the nucleus nor gets expelled from the atom. Although the Cole-Zou 2003 simulations support the stabilit ...

Light-like -deformations and scalar field theory via Drinfeld twist
... There have been attempts in the literature to obtain κ-Poincaré-Hopf algebra from the Abelian [9, 8] and Jordanian twist [10], but the problem with these twists is that they can not be expressed in terms of the Poincaré generators only. The κ-Poincaré-Hopf algebra was obtained using a twist in a ...
