Statistical Complexity of the Coriolis Antipairing Effect
Entropy, 2019 Using the entropic quantifier called statistical complexity, we investigate the interplay between (1) pairing interactions between fermions, can be viewed as analogous with superconductivity based on Cooper pairs; (2) rotations of the system as a whole ...

The European Physical Journal C, 2002 The path integral for ghost fermions, which is heuristically made use of in the Batalin- Fradkin-Vilkovisky approach to quantization of constrained systems, is derived from first principles. The derivation turns out to be rather different from that of physical fermions since the definition of Dirac states for ghost fermions is subtle.

Fermion and boson pairs in beamsplitters and Mach–Zehnder interferometers
JPhys PhotonicsIn this short topical review, we look at something typically considered trivial, but not given formally elsewhere—the behaviour of first multiple fermions, then multiple bosons, in a beamsplitter.

Observation of dynamical fermionization [PDF]
Science, 2020 Capturing the transformation Quantum statistics dictates the behavior of identical particles in the quantum world: Bosons like to congregate, whereas fermions avoid one another. However, strong interactions can cause a string of bosons to behave like fermions.

A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

International Journal of Modern Physics A, 2002 The current status of bounds on and limits of fermion determinants in two, three and four dimensions in QED and QCD is reviewed. A new lower bound on the two-dimensional QED determinant is derived. An outline of the demonstration of the continuity of this determinant at zero mass when the background magnetic field flux is zero is also given.

Advanced Science, EarlyView.First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...

Wilson fermions and the topological charge on the lattice
, 1986 Karsch F, Seiler E, Stamatescu IO. Wilson fermions and the topological charge on the lattice. Nuclear Physics, B. 1986;271(2):349-368.We investigate the realization on the lattice of the relation between the chiral properties of the fermions and the ...

Three-body contact for fermions. I. General relations
Comptes Rendus. PhysiqueWe consider the resonant Fermi gas, that is, two-component fermions in three dimensions interacting by a short-range potential of large scattering length. We introduce a quantity, the three-body contact, that determines several observables.

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.
