On a class of topological quantum field theories in three-dimensions [PDF]

, 1995
We investigate the Chung-Fukuma-Shapere theory, or Kuperberg theory, of three-dimensional lattice topological field theory. We construct a functor which satisfies the Atiyah's axioms of topological quantum field theory by reformulating the theory as ...

Variational analysis of low-lying states in supersymmetric Yang-Mills theory

Journal of High Energy Physics, 2019
We have calculated the masses of bound states numerically in N $$ \mathcal{N} $$ = 1 supersymmetric Yang-Mills theory with gauge group SU(2). Using the suitably optimised variational method with an operator basis consisting of smeared Wilson loops and ...

Triad second renormalization group

Journal of High Energy Physics, 2022
We propose a second renormalization group (SRG) in the triad representation of tensor networks. The SRG method improves two parts of the triad tensor renormalization group, which are the decomposition of intermediate tensors and the preparation of ...

Engineering a Spin‐Orbit Bandgap in Graphene‐Tellurium Heterostructures

Advanced Functional Materials, EarlyView.
Tellurium intercalation in epitaxial graphene on Ir(111) enables the emergence of a spin–orbit‐induced bandgap with energy spin splitting. By combining STM, ARPES, spin‐resolved ARPES, and DFT, two structural phases are identified, both exhibiting tunable electronic doping.

3d N = 4 $$ \mathcal{N}=4 $$ super-Yang-Mills on a lattice

Journal of High Energy Physics, 2018
In this paper we explore a new approach to studying three-dimensional N = 4 $$ \mathcal{N}=4 $$ super-Yang-Mills on a lattice. Our strategy is to complexify the Donaldson-Witten twist of four-dimensional N = 2 $$ \mathcal{N}=2 $$ super-Yang-Mills to make

Self‐Poled Halide Perovskite Ruddlesden‐Popper Ferroelectric‐Photovoltaic Semiconductor Thin Films and Their Energy Harvesting Properties

Advanced Functional Materials, EarlyView.
Low‐dimensional halide perovskite thin films, (BA)2(MA)n‐1PbnBr3n+1 (n = 1, 2), exhibit both semiconducting and ferroelectric properties, enabling mechanical and light energy harvesting. Using Cr/Cr₂O₃ or PCBM as barrier layers ensures reproducible ferroelectricity.

Spin foam models with finite groups

, 2011
Spin foam models, loop quantum gravity and group field theory are discussed as quantum gravity candidate theories and usually involve a continuous Lie group.

Spin squeezing in optical lattice clocks via lattice-based QND measurements

, 2008
Quantum projection noise will soon limit the best achievable precision of optical atomic clocks based on lattice-confined neutral atoms. Squeezing the collective atomic pseudo-spin via measurement of the clock state populations during Ramsey ...

The light bound states of N = 1 $$ \mathcal{N}=1 $$ supersymmetric SU(3) Yang-Mills theory on the lattice

Journal of High Energy Physics, 2018
In this article we summarise our results from numerical simulations of N = 1 $$ \mathcal{N}=1 $$ supersymmetric Yang-Mills theory with gauge group SU(3). We use the formulation of Curci and Veneziano with clover-improved Wilson fermions.

The glueball spectrum of SU(3) gauge theory in 3 + 1 dimensions

Journal of High Energy Physics, 2020
We calculate the low-lying glueball spectrum of the SU(3) lattice gauge theory in 3 + 1 dimensions for the range β ≤ 6.50 using the standard plaquette action.
