On the trace anomaly of a Weyl fermion [PDF]
Journal of High Energy Physics, 2016 We calculate the trace anomaly of a Weyl fermion coupled to gravity by using Fujikawa’s method supplemented by a consistent regulator. The latter is constructed out of Pauli-Villars regulating fields.

A corner reflector of graphene Dirac fermions as a phonon-scattering sensor
Nature Communications, 2019 Dirac fermion optics leverages p-n junctions and Klein tunnelling barriers present in materials to implement complex optical functions and devices, including reflectors, collimators, and Dirac fermion microscopes.

Fermion–fermion duality in 3+1 dimensions [PDF]
Annals of Physics, 2020 Dualities play a central role in both quantum field theories and condensed matter systems. Recently, a web of dualities has been discovered in 2+1 dimensions. Here, we propose in particular a generalization of the Son's fermion-fermion duality to 3+1 dimensions.

Entanglement in fermion systems [PDF]
Physical Review A, 2015 We analyze the problem of quantifying entanglement in pure and mixed states of fermionic systems with fixed number parity yet not necessarily fixed particle number. The "mode entanglement" between one single-particle level and its orthogonal complement is first considered, and an entanglement entropy for such a partition of a particular basis of the ...

The Calculation of Force in Lattice Quantum Chromodynamics [PDF]
arXiv, 2018 The calculation of force is most difficult part in lattice Quantum Chromodynamics (QCD). This lecture gives the details of the force calculation in one-loop Symanzik improved action, Wilson fermion with clover term, asqtad fermion, HISQ fermion, rooted staggered fermion, smeared fermion, staggered Wilson fermion, overlap fermion and domain wall fermion.

Radiative seesaw-type mechanism of fermion masses and non-trivial quark mixing [PDF]
, 2016 We propose a predictive inert two-Higgs doublet model, where the standard model (SM) symmetry is extended by $$S_{3}\otimes Z_{2}\otimes Z_{12}$$S3⊗Z2⊗Z12 and the field content is enlarged by extra scalar fields, charged exotic fermions and two heavy ...

Physics Letters B, 1974 Abstract Spontaneous violation of super-gauge symmetries is considered. One consequence must be the emergence of a particle with spin 1 2 and mass zero.

Operator Homology and Cohomology in Clifford Algebras
Cubo, 2010 In recent work, the authors used canonical lowering and raising operators to define Appell systems on Clifford algebras of arbitrary signature. Appell systems can be interpreted as polynomial solutions of generalized heat equations, and in probability ...

Large $$N_\mathrm{f}$$ N f for multiple representations
European Physical Journal C: Particles and Fields, 2021 We present an extension of the large- $$N_\mathrm{f}$$ N f formalism that allows one to study cases with multiple fermion representations. The pole structure in the beta function is traced back to the intrinsic non-abelian nature of the gauge group ...
