Fermion Number Conservation Isn't Fermion Conservation [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1993
A nonperturbative regularization of the Standard Model may have a superficially undesirable exact global U(1) symmetry corresponding to exact fermion number conservation.

Fermion Bags and A New Origin for a Fermion Mass [PDF]

open access: yesProceedings of The 32nd International Symposium on Lattice Field Theory — PoS(LATTICE2014), 2014
The fermion bag is a powerful idea that helps to solve fermion lattice field theories using Monte Carlo methods. Some sign problems that had remained unsolved earlier can be solved within this framework.

Four-Fermion Dynamics and Fermion Masses [PDF]

open access: yesProgress of Theoretical Physics Supplement, 1995
Four-fermion operators with large anomalous dimension may feed down mass to quarks and leptons from a heavy fourth family. No technicolor sector is required.

Fermionization of Two Distinguishable Fermions [PDF]

open access: yesPhysical Review Letters, 2012
In this work we study a system of two distinguishable fermions in a 1D harmonic potential. This system has the exceptional property that there is an analytic solution for arbitrary values of the interparticle interaction. We tune the interaction strength via a magnetic offset field and compare the measured properties of the system to the theoretical ...

Tangent Fermions: Dirac or Majorana Fermions on a Lattice Without Fermion Doubling

open access: yesAnnalen der Physik, 2023
AbstractMethods to discretize the Hamiltonian of a topological insulator or topological superconductor, without giving up on the topological protection of the massless excitations (respectively, Dirac fermions or Majorana fermions) are reviewed. The method of tangent fermions, pioneered by Richard Stacey, is singled out as being uniquely suited for ...

Fermion damping in a fermion-scalar plasma [PDF]

open access: yesPhysical Review D, 1999
In this article we study the dynamics of fermions in a fermion-scalar plasma. We begin by obtaining the effective in-medium Dirac equation in real time which is fully renormalized and causal and leads to the initial value problem. For a heavy scalar we find the novel result that the decay of the scalar into fermion pairs in the medium leads to damping ...

Fermions without Fermion Fields [PDF]

open access: yesPhysical Review Letters, 2005
It is shown that an arbitrary Fermion hopping hamiltonian can be represented by a system with no fermion fields, generalising earlier results by M. Levin & X.G. Wen [Phys Rev B 67, 245316 (2003)]. All the operators in the hamiltonian of resulting description obey the principle of locality, that operators associated with different sites commute ...
