Phonon Mediated Transresistivity in a Double Layer Composite Fermion System

, 2007
We consider the fractional drag in a double layer system of two-dimensional electrons in the half-filled lowest Landau level. At sufficiently large interlayer separations the drag is dominated by exchange of acoustic phonons and exhibits novel ...

A pseudo-fermion propagator approach to the fermion sign problem

The Journal of Chemical Physics
In this work, within the framework of path integral Monte Carlo, we construct a pseudo-fermion propagator by replacing the original fermionic determinant with its absolute value. This modified propagator defines an auxiliary system free from the fermion sign problem, enabling efficient simulations of fermionic systems.

New Aspects of Flavour Model Building in Supersymmetric Grand Unification [PDF]

, 2010
We derive predictions for Yukawa coupling ratios within Grand Unified Theories generated from operators with mass dimension four and five. These relations are a characteristic property of unified flavour models and can reduce the large number of free ...

Fermion bag approach to lattice field theories

, 2010
We propose a new approach to the fermion sign problem in systems where there is a coupling U such that when it is infinite the fermions are paired into bosons, and there is no fermion permutation sign to worry about.

Fermion-Fermion Gluing by Means of Unobservable Scalar Bosons

, 2002
A theory of several fermion fields interacting with several scalar fields is suggested. The model is nonlocal and is partially solvable under arbitrary choice of its formfactors. The latter are shown to determine the resulting fermion-fermion interaction.

Localization of matter fields on flat fermion brane

European Physical Journal C: Particles and Fields
In this paper, we investigate the localization of matter fields on a flat fermion thick brane. To localize scalar and fermion fields within a five-dimensional spacetime, we introduce the Yukawa coupling mechanism.

A New Relativistic Wave Equation for a Massive Boson and Fermion System [PDF]

, 2015
This article pretends to show some results from the study of The Relativistic Wave Equation in order to describe a massive system of boson and fermion. We defined the scattering matrix Vf i on the electromagnetic case and concurrently we extended it to ...
