Spontaneous Symmetry Breakdown in non-relativistic Quantum Mechanics
R. Munoz-Vega, A. Garcia-Quiroz, Ernesto Lopez-Chavez +1
The advantages and disadvantages of some pedagogical non-relativistic quantum-mechanical models, used to illustrate spontaneous symmetry breakdown, are discussed. A simple quantum-…
Simple models exhibiting spontaneous symmetry breakdown in classical and non-relativistic quantum mechanics
R. Munoz, A. Garcia-Quiroz, Ernesto Lopez-Chavez +1
First, the properties of a classical model of spontaneous symmetry breakdown are analyzed. Then, the pros and cons of some pedagogical non-relativistic quantum-mechanical models, a…
Relationship between (2+1) and 3+1)--Friedmann--Robertson--Walker cosmologies
A. Garcia, M. Cataldo, S. del Campo
In this work we establish the correspondence between solutions to the Friedmann--Robertson--Walker cosmologies for perfect fluid and scalar field sources, where both ones fulfill s…
