From square plaquettes to triamond lattices for SU(2) gauge theory

open access: yesCommunications Physics
Lattice gauge theory should be able to address significant new scientific questions when implemented on quantum computers. In practice, error-mitigation techniques have already allowed encouraging progress on small lattices.

Microscopic Description of 2D Topological Phases, Duality, and 3D State Sums

open access: yesAdvances in Mathematical Physics, 2010
Doubled topological phases introduced by Kitaev, Levin, and Wen supported on two-dimensional lattices are Hamiltonian versions of three-dimensional topological quantum field theories described by the Turaev-Viro state sum models.

Exact solution of Z_2 Chern-Simons model on a triangular lattice

open access: yes, 2005
We construct the Hamiltonian description of the Chern-Simons theory with Z_n gauge group on a triangular lattice. We show that the Z_2 model can be mapped onto free Majorana fermions and compute the excitation spectrum. In the bulk the spectrum turns out

Anomalous Phonon Softening with Inherent Strain in Wrinkled Monolayer WSe2

open access: yesAdvanced Materials, EarlyView.
This study introduces the first discovery of a new local strain indicator, A2′′(Γ)$A_2^{^{\prime\prime}}( \Gamma )$ mode, for monolayer WSe2‐based excitonic applications including single photon emitter by using tip‐enhanced Raman spectroscopy. The correlative investigation with density functional perturbation theory provides the origin of the anomalous

Lattice Hamiltonian for adjoint QCD2

open access: yesJournal of High Energy Physics
We introduce a Hamiltonian lattice model for the (1 + 1)-dimensional SU(N c ) gauge theory coupled to one adjoint Majorana fermion of mass m. The discretization of the continuum theory uses staggered Majorana fermions.

Hamiltonian Renormalization V: Free Vector Bosons

open access: yesFrontiers in Astronomy and Space Sciences, 2021
In a recent proposal we applied methods from constructive QFT to derive a Hamiltonian Renormalization Group in order to employ it ultimately for canonical quantum gravity.

Finite-element quantum field theory

open access: yes, 1996
An alternative approach to lattice gauge theory has been under development for the past decade. It is based on discretizing the operator Heisenberg equations of motion in such a way as to preserve the canonical commutation relations at each lattice site.

Method for Extracting the Glueball Wave Function [PDF]

open access: yes, 1997
We describe a nonperturbative method for calculating the QCD vacuum and glueball wave functions, based on an eigenvalue equation approach to Hamiltonian lattice gauge theory.

Loop-string-hadron formulation of an SU(3) gauge theory with dynamical quarks

open access: yes, 2023
Towards the goal of quantum computing for lattice quantum chromodynamics, we present a loop-string-hadron (LSH) framework in 1+1 dimensions for describing the dynamics of SU(3) gauge fields coupled to staggered fermions.

Current Control of Spin Helicity and Nonreciprocal Charge Transport in a Multiferroic Conductor

open access: yesAdvanced Materials, EarlyView.
A conducting multiferroic state of spin origin with both electronic polarity (P) and magnetization (M) can be controlled and detected by electric current in a high‐temperature helimagnet YMn6Sn6. The underlying concept is the coupling of the electric current with the toroidal moment T∼P×M$\bm{T}\sim \bm{P}\ensuremath{\times{}}\bm{M}$.
