Lattice Hamiltonian for adjoint QCD2
Journal of High Energy PhysicsWe 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.

Lattice implementation of Abelian gauge theories with Chern–Simons number and an axion field
Nuclear Physics B, 2018 Real time evolution of classical gauge fields is relevant for a number of applications in particle physics and cosmology, ranging from the early Universe to dynamics of quark–gluon plasma.

Chiral Fermions and Anomalies on a Finite Lattice
, 1992 A recent proposal by Kaplan for a chiral gauge theory on the lattice is tested with background gauge fields. The spectrum of the finite lattice Hamiltonian is calculated and the existence of a chiral fermion is demonstrated. Lattice doublers are found to

Gauge-invariant Hamiltonian formulation of lattice Yang-Mills theory and the Heisenberg double [PDF]
, 1995 It it known that to get the usual Hamiltonian formulation of lattice Yang-Mills theory in the temporal gauge $A_{0}=0$ one should place on every link the cotangent bundle of a Lie group.

Advanced Functional Materials, EarlyView.Tin hexathiophosphate memristors leverage intrinsic nanopores together with a guided filament formation strategy to regulate titanium ion motion and switching behavior. The devices support reliable nonvolatile memory and reconfigurable logic‐in‐memory, demonstrating 14 Boolean logic functions in a single cell.

Discrete Abelian Gauge Theories for Quantum Simulations of QED
, 2015 We study a lattice gauge theory in Wilson's Hamiltonian formalism. In view of the realization of a quantum simulator for QED in one dimension, we introduce an Abelian model with a discrete gauge symmetry $\mathbb{Z}_n$, approximating the $U(1)$ theory ...

A many-body treatment of Hamiltonian lattice gauge theory [PDF]
Nuclear Physics A, 2000 The Hamiltonian SU(N) lattice gauge theory is studied in terms of angular variables. We show that the one-plaquette problem can be mapped onto a fermion problem for arbitrary N. The low-lying energy spectrum is investigated numerically.

Probing Cellular Activity Via Charge‐Sensitive Quantum Nanoprobes
Advanced Materials, EarlyView.A new quantum sensing modality detects shifts in zero‐field splitting caused by charge rearrangement with diamond nanocrystals in response to cellular activity. These electric‐field‐driven effects provide an alternative to temperature‐based interpretations, enabling real‐time, single‐cell readout of inflammation.

Projective spacetime symmetry of spacetime crystals
Communications Physics, 2023 Wigner’s seminal work on the Poincaré group revealed one of the fundamental principles of quantum theory: symmetry groups are projectively represented. The condensed-matter counterparts of the Poincaré group could be the spacetime groups of periodically ...
