Fermion Number Conservation Isn't Fermion Conservation [PDF]
Nuclear 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.

Fermionization of Two Distinguishable Fermions [PDF]
Physical 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 ...

Fermionic Minimal Models [PDF]
Physical Review Letters, 2021 We show that there is a fermionic minimal model, i.e. a 1+1d conformal field theory which contains operators of half-integral spins in its spectrum, for each $c=1-6/m(m+1)$, $m\ge 3$. This generalizes the Majorana fermion for $c=1/2$, $m=3$ and the smallest $\mathcal{N}{=}1$ supersymmetric minimal model for $c=7/10$, $m=4$.

Fermions without Fermion Fields [PDF]
Physical 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 ...

Nuclear 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 ...

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

Lattice-fermionic Casimir effect and topological insulators
Physical Review Research, 2021 The Casimir effect arises from the zero-point energy of particles in momentum space deformed by the existence of two parallel plates. For degrees of freedom on the lattice, its energy-momentum dispersion is determined so as to keep a periodicity within ...
