Majorana neutrino as Bogoliubov quasiparticle
Physics Letters B, 2017 We suggest that the Majorana neutrino should be regarded as a Bogoliubov quasiparticle that is consistently understood only by use of a relativistic analogue of the Bogoliubov transformation.

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.

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 ...

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).

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

New Interacting Boson Fermion-Fermion Model results [PDF]
EPJ Web of ConferencesWe 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 ...

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.

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.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
