Ternary SU(3)-group symmetry and its possible applications in hadron-quark substructure. Towards a new spinor-fermion structure [PDF]

EPJ Web of Conferences, 2019
The questions on the existence of the three color quark symmetry and three quark-lepton generations could have the origin associated with the new exotic symmetries outside the Cartan-Killing-Lie algebras/groups.

Renormalizable extension of the Abelian Higgs-Kibble model with a dim.6 derivative operator

SciPost Physics Proceedings, 2023
We present a new approach to the consistent subtraction of a non power-counting renormalizable extension of the Abelian Higgs-Kibble (HK) model supplemented by a dim. 6 derivative-dependent operator controlled by the parameter $z$.

The Extension Structure of 2D Massive Current Algebras

, 1992
The extension structure of the 2-dimensional current algebra of non-linear sigma models is analysed by introducing Kostant Sternberg $(L,M)$ systems. It is found that the algebra obeys a two step extension by abelian ideals.

Observation of ν = 5/2 Fractional Quantum Hall Effect in Trilayer Graphene Proximitized by V‐Doped WSe2

Advanced Materials, EarlyView.
Even‐denominator 5/2 fractional state in trilayer graphene/V‐doped WSe2 heterostructure, mediated by proximitized magnetism, is demonstrated. An exceptionally high energy gap ∆5/2 (48 K) for the 5/2 state, significantly surpassing previous values in semiconductors and bilayer graphene (∆5/2 < 1 K) is reported.

Characterisation of Locally Compact Abelian Groups Having Spectral Synthesis

Forum of Mathematics, Sigma
In this paper we solve a long-standing problem which goes back to Laurent Schwartz’s work on mean periodic functions. Namely, we completely characterize those locally compact Abelian groups having spectral synthesis. So far a characterization theorem was

A toy model for background independent string field theory

Journal of High Energy Physics, 2022
We study gauge theories of background fields associated to BRST quantized spinning particle models and identify background-independent algebraic structures which allow to systematically reduce the spectrum of fields and subject some of them to dynamical ...

Landau-Ginzburg Theories for Non-Abelian Quantum Hall States

, 1998
We construct Landau-Ginzburg effective field theories for fractional quantum Hall states -- such as the Pfaffian state -- which exhibit non-Abelian statistics.

Photoluminescence Properties of Type‐II GaSb/GaAs Quantum Rings

Advanced Photonics Research, EarlyView.
This study examines the magneto‐optical properties of GaSb/GaAs quantum rings (QRs) using photoluminescence spectroscopy. Recombination dynamics in single‐ and ten‐layer structures are analyzed through activation energy extraction, optical absorption profiling, and observation of a strong excitation‐induced blue shift. Carrier lifetime is also increase

On Non-Abelian Duality

, 1994
A general study of non-abelian duality is presented. We first identify a possible obstruction to the conformal invariance of the dual theory for non-semisimple groups. We construct the exact non-abelian dual for any Wess-Zumino-Witten (WZW) model for any

Multiscale Cell–Cell Interactive Spatial Transcriptomics Analysis

Advanced Science, EarlyView.
In this study, we present the MultiScale Cell‐Cell Interactive Spatial Transcriptomics Analysis method, which unites the strengths of spatially resolved deep learning techniques with a topological representation of multi‐scale cell‐cell similarity relations.
