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 ...

Fermion-Higgs model with strong Wilson-Yukawa coupling in two dimensions

, 1992
The fermion mass spectrum is studied in the quenched approximation in the strong coupling vortex phase (VXS) of a globally U(1)$_L \otimes$U(1)$_R$ symmetric scalar-fermion model in two dimensions. In this phase fermion doublers can be completely removed

Discerning Fermions

The British Journal for the Philosophy of Science, 2008
We demonstrate that the quantum-mechanical description of composite physical systems of an arbitrary number of similar fermions in all their admissible states, mixed or pure, for all finite-dimensional Hilbert spaces, is not in conflict with Leibniz’s Principle of the Identity of Indiscernibles (PII).

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.

On renormalizability of the massless Thirring model

, 2006
We discuss the renormalizability of the massless Thirring model in terms of the causal fermion Green functions and correlation functions of left-right fermion densities.

Symplectic fermions [PDF]

Nuclear Physics B, 2000
We study two-dimensional conformal field theories generated from a ``symplectic fermion'' - a free two-component fermion field of spin one - and construct the maximal local supersymmetric conformal field theory generated from it. This theory has central charge c=-2 and provides the simplest example of a theory with logarithmic operators. Twisted states

On the spectrum of the Schrödinger operator for a three-particle system on a lattice

Учёные записки Казанского университета: Серия Физико-математические науки
A 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 ...

New Interacting Boson Fermion-Fermion Model results [PDF]

EPJ Web of Conferences
We 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 ...

Matching high-energy electroweak fermion loops onto the Fermi theory without higher dimensional operators

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

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.
