Scattering of fermions in the Yukawa theory coupled to unimodular gravity

open access: yesEuropean 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

Equivalence between Fermion-to-Qubit Mappings in two Spatial Dimensions

open access: yesPRX Quantum, 2023
We argue that all locality-preserving mappings between fermionic observables and Pauli matrices on a two-dimensional lattice can be generated from the exact bosonization in Chen et al. [Ann. Phys. (N.

On ghost fermions [PDF]

open access: yesThe European Physical Journal C, 2002
The path integral for ghost fermions, which is heuristically made use of in the Batalin- Fradkin-Vilkovisky approach to quantization of constrained systems, is derived from first principles. The derivation turns out to be rather different from that of physical fermions since the definition of Dirac states for ghost fermions is subtle.

Majorana neutrino as Bogoliubov quasiparticle

open access: yesPhysics 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.

Möbius Fermions [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2006
We introduce a new domain wall operator that represents a full (real) Moebius transformation of a given non-chiral Dirac kernel. Shamir's and Borici's domain wall fermions are special cases of this new class. By tuning the parameters of the Moebius operator and by introducing a new Red/Black preconditioning, we are able to reduce the computational ...

Dynamical collapse in a degenerate binary fermion mixture using a hydrodynamic model

open access: yes, 2006
We use a time-dependent dynamical hydrodynamic model to study a collapse in a degenerate fermion-fermion mixture (DFFM) of different atoms. Due to a strong Pauli-blocking repulsion among identical spin-polarized fermions at short distances there cannot ...

Fermion zero-modes of a new constrained instanton in Yang-Mills-Higgs theory [PDF]

open access: yes, 1997
Self-consistent Ansaetze are presented for the left- and right-handed isodoublet fermion zero-modes of the constrained instanton Istar in the vacuum sector of euclidean SU(2) Yang-Mills-Higgs theory. These left- and right-handed fermion wave functions do

Observation of dynamical fermionization [PDF]

open access: yesScience, 2020
Capturing the transformation Quantum statistics dictates the behavior of identical particles in the quantum world: Bosons like to congregate, whereas fermions avoid one another. However, strong interactions can cause a string of bosons to behave like fermions.

Fermion Interactions in the Wilson Yukawa Approach for Lattice Chiral Gauge Theories

open access: yes, 1992
We consider fermion-gauge couplings in the Wilson-Yukawa approach for lattice chiral gauge theories. At the leading order of a fermionic hopping parameter expansion we find that the fermion-gauge coupling has a chiral and tree-like structure.
