Nuclear Physics B, 2020 We derive the conditions for matching high-energy renormalizable Quantum Field Theories onto low-energy nonrenormalizable ones by means of the FDR approach described in [1]. Our procedure works order-by-order in the loop expansion and avoids the addition

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

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 nonperturbative study of three dimensional quantum electrodynamics with N flavours of fermion [PDF]
, 1990 This work is concerned with the breaking of chiral symmetry in gauge theories and the associated generation of a dynamical mass scale. We investigate this phenomenon in the context of a simple model, three dimensional QED, where the complicating factor ...

Phases of a strongly coupled four-fermion theory [PDF]
, 2018 We present ongoing investigations of a four-dimensional lattice field theory with four massless reduced staggered fermions coupled through an SU(4)-invariant fourfermion interaction.

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.

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

Fermion masses through four-fermion condensates
, 2016 Fermion masses can be generated through four-fermion condensates when symmetries prevent fermion bilinear condensates from forming. This less explored mechanism of fermion mass generation is responsible for making four reduced staggered lattice fermions ...

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.
