Probabilistic Q-function distributions in fermionic phase-space
New Journal of Physics, 2015 We obtain a positive probability distribution or Q -function for an arbitrary fermionic many-body system. This is different to previous Q -function proposals, which were either restricted to a subspace of the overall Hilbert space, or used Grassmann ...

Scattering of fermions in the Yukawa theory coupled to unimodular gravity
European Physical Journal C: Particles and Fields, 2018 We compute the lowest order gravitational UV divergent radiative corrections to the S matrix element of the $$fermion + fermion\rightarrow fermion + fermion$$ fermion+fermion→fermion+fermion scattering process in the massive Yukawa theory, coupled either

High-Temperature Atomic Superfluidity in Lattice Boson-Fermion Mixtures [PDF]
, 2004 We consider atomic Bose-Fermi mixtures in optical lattices and study the superfluidity of fermionic atoms due to s-wave pairing induced by boson-fermion interactions.

Majorana neutrino as Bogoliubov quasiparticle
Physics Letters B, 2017 We suggest that the Majorana neutrino should be regarded as a Bogoliubov quasiparticle that is consistently understood only by use of a relativistic analogue of the Bogoliubov transformation.

Light Quark Simulations With FLIC Fermions [PDF]
, 2002 Hadron masses are calculated in quenched lattice QCD in order to probe the scaling behavior of a novel fat-link clover fermion action in which only the irrelevant operators of the fermion action are constructed using APE-smeared links. Light quark masses

Testing a dynamical origin of Standard Model fermion masses [PDF]
, 2016 We discuss a test of the Standard Model fermion mass origin in models of dynamical electroweak symmetry breaking. The couplings of composite pseudoscalar resonances to top quarks allow to distinguish high-scale Extended-Technicolor-type fermion mass ...

The self-consistent field model for Fermi systems with account of three-body interactions
Condensed Matter Physics, 2015 On the basis of a microscopic model of self-consistent field, the thermodynamics of the many-particle Fermi system at finite temperatures with account of three-body interactions is built and the quasiparticle equations of motion are obtained. It is shown

Integrable boundary impurities in the t-J model with different gradings
, 2000 We investigate the generalized supersymmetric $t-J$ model with boundary impurities in different gradings. All three different gradings: fermion, fermion, boson (FFB), boson, fermion, fermion (BFF) and fermion, boson, fermion (FBF), are studied for the ...

SSOR Preconditioning of Improved Actions [PDF]
, 1997 We generalize local lexicographic SSOR preconditioning for the Sheikholeslami-Wohlert improved Wilson fermion action and the truncated perfect free fermion action. In our test implementation we achieve performance gains as known from SSOR preconditioning
