On the spectrum of the Schrödinger operator for a three-particle system on a lattice
Учёные записки Казанского университета: Серия Физико-математические наукиA three-particle discrete Schrödinger operator Hµ,γ(K) :≡ Hµ,γ(K), K = (K, K, K) ∈ 𝕋3 , which is associated with a system of three particles (two fermions of mass 1 and one other particle of mass m = 1/γ ,) interacting via pairwise repulsive contact ...

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.

Advanced Materials, EarlyView.Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Lattice simulation with the Majorana positivity
EPJ Web of Conferences, 2018 While the sign problem of the Dirac fermion is conditioned by the semipositivity of a determinant, that of the Majorana fermion is conditioned by the semipositivity of a Pfaffian.

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

3D Fermion representation of affine Yangian
Nuclear Physics B, 2022 In this paper, we give the 3D (3 dimensional) Fermion representation of affine Yangian of gl(1). In special case h1=1,h2=−1,h3=0, the 3D Fermion operators Γm→ and Γm→⁎ become γm→ and γm→⁎ which have relations with 2D Fermions.

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.

Fermions without Fermions: The Nicolai Map Revisited [PDF]
Progress of Theoretical Physics, 1985 Summary: For supersymmetric fermion-boson models, the Nicolai map is so designed as (i) to cancel the fermion determinant and (ii) to reduce the boson measure to a free one. By analyzing a simple model, it is shown that (i) is realized only for suitable matrix elements of the evolution operator, but not for the trace; the realization requires proper ...

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

Boson-fermion pairing in a boson-fermion environment [PDF]
Physical Review A, 2005 Propagation of a Boson-Fermion (B-F) pair in a B-F environment is considered. The possibility of formation of stable strongly correlated B-F pairs, embedded in the continuum, is pointed out. The new Fermi gas of correlated B-F pairs shows a strongly modified Fermi surface.
