Common origin of inverse seesaw and baryon asymmetry
Physics Letters B, 2020 In the inverse seesaw scenario, several fermion singlets have a small Majorana mass term. We show such Majorana masses can be suppressed by some heavy fermion and/or Higgs singlets after a global symmetry is spontaneously broken.

Journal of High Energy Physics, 2022 I discuss the 2-flavor Schwinger model with θ = 0 and small equal and opposite fermion masses (or θ = π with equal masses). The massless model has an unparticle sector with unbroken conformal symmetry.

The Mysteries of Fermions [PDF]
International Journal of Theoretical Physics, 2010 It is conjectured that all known fermions are topological solitons. This could explain the non-observation of bosonic leptons and baryons and provide a physical mechanism for the Pauli exclusion principle.

Advanced Science, EarlyView.A temperature‐driven magnetic anisotropy crossover is revealed in the Dirac kagome magnet Fe3Ge with a distorted kagome lattice. The transition from easy‐plane to easy‐axis magnetic anisotropy stabilizes robust Bloch‐type skyrmions over an exceptionally wide temperature window of 375–650 K.

Shallow trimers of two identical fermions and one particle in resonant regimes
SciPost Physics, 2022 We consider two identical fermions interacting in the p-wave channel. Each fermion also interacts with another particle in the vicinity of an s-wave resonance.

The British Journal for the Philosophy of Science, 2008 We demonstrate that the quantum-mechanical description of composite physical systems of an arbitrary number of similar fermions in all their admissible states, mixed or pure, for all finite-dimensional Hilbert spaces, is not in conflict with Leibniz’s Principle of the Identity of Indiscernibles (PII).

Probing axion mediated fermion–fermion interaction by means of entanglement
Physics Letters B, 2020 We propose a new approach in the investigation and detection of axion and axion–like particles based on the study of the entanglement for two interacting fermions.

Notions of Fermionic Entropies for Causal Fermion Systems
Mathematical Physics, Analysis and GeometryAbstract The fermionic von Neumann entropy, the fermionic entanglement entropy and the fermionic relative entropy are defined for causal fermion systems. Our definition makes use of entropy formulas for quasi-free fermionic states in terms of the reduced one-particle density operator.

Nuclear Physics B, 2000 We study two-dimensional conformal field theories generated from a ``symplectic fermion'' - a free two-component fermion field of spin one - and construct the maximal local supersymmetric conformal field theory generated from it. This theory has central charge c=-2 and provides the simplest example of a theory with logarithmic operators. Twisted states
