Phenomenological profile of scotogenic fermionic dark matter
Journal of High Energy Physics, 2023 We consider the possibility that neutrino masses arise from the exchange of dark matter states. We examine in detail the phenomenology of fermionic dark matter in the singlet-triplet scotogenic model.

Missing final state puzzle in the monopole-fermion scattering
Physics Letters B, 2022 It has been known that when a charged fermion scatters off a monopole, the fermion in the s-wave component must flip its chirality, i.e., fermion number violation must happen.

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 ...

Quantum transport in d-dimensional lattices
New Journal of Physics, 2016 We show that both fermionic and bosonic uniform d -dimensional lattices can be reduced to a set of independent one-dimensional chains. This reduction leads to the expression for ballistic energy fluxes in uniform fermionic and bosonic lattices.
