Geometrical contribution to neutrino mass matrix
European Physical Journal C: Particles and Fields, 2019 The dynamics of fermions on curved spacetime requires a spin connection, which contains a part called contorsion, an auxiliary field without dynamics but fully expressible in terms of the axial current density of fermions. Its effect is the appearance of

Effect of mediated interactions on a Hubbard chain in mixed-dimensional fermionic cold atoms
Physical Review Research, 2020 Cold atom experiments can now realize mixtures where different components move in different spatial dimensions. We investigate a fermion mixture where one species is constrained to move along a one-dimensional lattice embedded in a two-dimensional ...

Singlet-doublet fermion origin of dark matter, neutrino mass and W-mass anomaly
Physics Letters B, 2022 Motivated by the recently reported anomaly in W boson mass by the CDF collaboration with 7σ statistical significance, we consider a singlet-doublet (SD) Majorana fermion dark matter (DM) model where the required correction to W boson mass arises from ...

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).

Advanced Physics Research, EarlyView.This comprehensive density functional theory analysis investigates the structural, electronic, optical, mechanical, and thermoelectric properties of FeSi, c‐RhSi, and o‐RhSi. Results reveal distinct electronic and optical contrasts among the materials.

, 2017 Motivated by potential applications to ultracold matter, we perform a theoretical study of Majorana fermions confined to a finite volume, whose boundary conditions are characterized by self-adjoint extension parameters.

Discerning "indistinguishable" quantum systems [PDF]
, 2012 In a series of recent papers, Simon Saunders, Fred Muller and Michael Seevinck have collectively argued, against the folklore, that some non-trivial version of Leibniz's principle of the identity of indiscernibles is upheld in quantum mechanics.

Composite fermions and their pair states in a strongly-coupled Fermi liquid
Nuclear Physics B, 2018 Our goal is to understand the phenomena arising in optical lattice fermions at low temperature in an external magnetic field. Varying the field, the attraction between any two fermions can be made arbitrarily strong, where composite bosons form via so ...

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
