Multi-component dark matter: the vector and fermion case [PDF]
The European Physical Journal C, 2017 Multi-component dark matter scenarios constitute natural extensions of standard single-component setups and offer attractive new dynamics that could be adopted to solve various puzzles of dark matter.

Is distinct location evidence of distinct objects? Multilocation and the problem of parsimony
Analytic Philosophy, EarlyView., 2023 Abstract For an object to be multilocated is for it to wholly occupy disjoint spatial regions simultaneously. If multilocation is possible, it is possible that a multilocated particle is wholly located at 1080 distinct locations, such that it constitutes a particle‐for‐particle duplicate of the actual universe.

Magneto-optical conductance of Kane fermion gas in low frequencies
New Journal of Physics, 2019 Kane fermion is the counterpart of the Dirac fermion with pseudospin-1. Due to the existence of a bunch of gapless modes associated with Landau levels, the magnetic transport property of Kane fermion gas is very different from that of the Dirac semimetal.

Equivalence between Fermion-to-Qubit Mappings in two Spatial Dimensions
PRX Quantum, 2023 We argue that all locality-preserving mappings between fermionic observables and Pauli matrices on a two-dimensional lattice can be generated from the exact bosonization in Chen et al. [Ann. Phys. (N.

Evidence for Weyl fermions in a canonical heavy-fermion semimetal YbPtBi [PDF]
Nature Communications, 2017 The manifestation of Weyl fermions in strongly correlated electron systems is of particular interest. We report evidence for Weyl fermions in the heavy fermion semimetal YbPtBi from electronic structure calculations, angle-resolved photoemission ...

New Interacting Boson Fermion-Fermion Model results [PDF]
EPJ Web of ConferencesWe present a new application of the Interacting Boson Model (IBM) and its extensions for describing double charge exchange reactions. The study of double charge exchange reactions induced by heavy ions involving candidate nuclei for neutrinoless double ...

Exterior calculus and fermionic quantum computation [PDF]
J.Phys. A51, 445301 (2018), 2018 Exterior calculus with its three operations meet, join and hodge star complement, is used for the representation of fermion-hole systems and for fermionic analogues of logical gates. Two different schemes that implement fermionic quantum computation, are proposed.

Exact Boson-Fermion Duality on a 3D Euclidean Lattice. [PDF]
Physical Review Letters, 2017 The idea of statistical transmutation plays a crucial role in descriptions of the fractional quantum Hall effect. However, a recently conjectured duality between a critical boson and a massless two-component Dirac fermion extends this notion to gapless ...

Phases Of Adjoint QCD$_3$ And Dualities
SciPost Physics, 2018 We study 2+1 dimensional gauge theories with a Chern-Simons term and a fermion in the adjoint representation. We apply general considerations of symmetries, anomalies, and renormalization group flows to determine the possible phases of the theory as a

Recombination in the universal four-fermion system
Physics Letters B, 2021 In the systems of spin 12 fermions with resonant S-wave interactions supporting only weakly bound dimers the antisymmetry forbids recombination of three (or more) fermions at zero energy. However, the fermion-fermion-dimer recombination is only partially
