Monte-Carlo sampling of self-energy matrices within sigma-models derived from Hubbard-Stratonovich transformed coherent state path integrals
Bernhard Mieck
The 'Neumann-Ulam' Monte-Carlo sampling is described for the calculation of a matrix inversion or a Green function in case of Hubbard-Stratonovich (HS-)transformed coherent state p…
Ensemble averaged coherent state path integral for disordered bosons with a repulsive interaction and derivation of a nonlinear sigma model
Bernhard Mieck
A coherent state path integral is considered for bosons with an ensemble average of a random potential and with an additional, repulsive interaction in the context of BEC under inc…
Fermionic coherent state path integral for ultrashort laser pulses and transformation to a field theory of coset matrices
Bernhard Mieck
A coherent state path integral of anti-commuting fields is considered for a two-band, semiconductor-related solid which is driven by a ultrashort, classical laser field. We describ…
Hubbard-Stratonovich transformations to self-energies with coset decomposition to anomalous pair condensates for the standard model of electroweak interactions
Bernhard Mieck
The standard model of the strong and electroweak interactions is transformed from the ordinary path integral with the Lagrangians of quarks and leptons and with the Abelian and non…
Field theory with coherent states for many-body problems with specified particle- and symmetry- quantum numbers (Non-relativistic electrons in a central potential and an external magnetic field)
Bernhard Mieck
Coherent state path integrals are applied to a many-body problem for non-relativistic electrons in a central potential and an external magnetic field; however, in comparison to pre…
Coherent state path integral and nonlinear sigma model for a condensate composed of fermions with precise, discrete steps in the time development
Bernhard Mieck
A coherent state path integral is considered for fermions with precise, discrete time separation. We derive in detail a nonlinear sigma model of a pair condensate concerning the pr…
