Fermion condensation and super pivotal categories [PDF]
Journal of Mathematics and Physics, 2017 We study fermionic topological phases using the technique of fermion condensation. We give a prescription for performing fermion condensation in bosonic topological phases which contain a fermion. Our approach to fermion condensation can roughly be understood as coupling the parent bosonic topological phase to a phase of physical fermions, and ...

Producing a new fermion in coherent elastic neutrino-nucleus scattering: from neutrino mass to dark matter [PDF]
Journal of High Energy Physics, 2018 We consider the production of a new MeV-scale fermion in coherent elastic neutrino-nucleus scattering. The effect on the measurable nucleon recoil spectrum is calculated. Assuming that the new fermion couples to neutrinos and quarks via a singlet scalar,

Is the Composite Fermion a Dirac Particle? [PDF]
Physical Review X, 2015 We propose a particle-hole symmetric theory of the Fermi-liquid ground state of a half-filled Landau level. This theory should be applicable for a Dirac fermion in the magnetic field at charge neutrality, as well as for the ν=1/2 quantum Hall ground ...

Consideration of Additive Quantum Numbers of Fermions and Their Conservations
Universe, 2021 Two new flavor quantum numbers D and U for down and up quarks, respectively, are introduced, and then quark quantum number H is proposed as the sum of the flavor quantum numbers of quarks. Moreover, lepton quark-like quantum number HL and finally fermion

Fermion mass hierarchies from modular symmetry [PDF]
Journal of High Energy Physics, 2020 We show how quark and lepton mass hierarchies can be reproduced in the framework of modular symmetry. The mechanism is analogous to the Froggatt-Nielsen (FN) mechanism, but without requiring any Abelian symmetry to be introduced, nor any Standard Model ...

Deep scaffold hopping with multimodal transformer neural networks
Journal of Cheminformatics, 2021 Scaffold hopping is a central task of modern medicinal chemistry for rational drug design, which aims to design molecules of novel scaffolds sharing similar target biological activities toward known hit molecules.

Compact fermion to qubit mappings [PDF]
Physical review B, 2020 Mappings between fermions and qubits are valuable constructions in physics. To date only a handful exist. In addition to revealing dualities between fermionic and spin systems, such mappings are indispensable in any quantum simulation of fermionic ...

Discovery of a Weyl fermion semimetal and topological Fermi arcs [PDF]
Science, 2015 Weyl physics emerges in the laboratory Weyl fermions—massless particles with half-integer spin—were once mistakenly thought to describe neutrinos. Although not yet observed among elementary particles, Weyl fermions may exist as collective excitations in ...

Signatures of the Adler–Bell–Jackiw chiral anomaly in a Weyl fermion semimetal [PDF]
Nature Communications, 2016 Weyl semimetals provide the realization of Weyl fermions in solid-state physics. Among all the physical phenomena that are enabled by Weyl semimetals, the chiral anomaly is the most unusual one.

Distinguishable cash, bosonic bitcoin, and fermionic non-fungible token
Frontiers in Physics, 2023 Modern technology has brought novel types of wealth. In contrast to hard cash, digital currency does not have a physical form. It exists in electronic forms only. To date, it has not been clear what impacts its ongoing growth will have, if any, on wealth
