Chiral gauge theories on the lattice without gauge fixing?
, 1993 We discuss two proposals for a non-perturbative formulation of chiral gauge theories on the lattice. In both cases gauge symmetry is broken by the regularization. We aim at a dynamical restoration of symmetry.

High Temperature Symmetry Nonrestoration and Inverse Symmetry Breaking on Extra Dimensions [PDF]
, 2009 We study $D$-dimensional gauge theory with an extra dimension of a circle at finite temperature. We mainly focus on the expectation value of the gauge field for the direction of the extra dimension, which is the order parameter of the gauge symmetry ...

Instanton operators and symmetry enhancement in 5d supersymmetric quiver gauge theories [PDF]
, 2015 A bstractWe consider general 5d SU(N ) quiver gauge theories whose nodes form an ADE Dynkin diagram of type G. Each node has SU(Ni) gauge group of general rank, Chern-Simons level κi and additional wi fundamentals.

Neural Network Adaptive Control With Long Short‐Term Memory
International Journal of Adaptive Control and Signal Processing, EarlyView.ABSTRACT In this study, we propose a novel adaptive control architecture that provides dramatically better transient response performance compared to conventional adaptive control methods. This is accomplished by the synergistic employment of a traditional adaptive neural network (ANN) controller and a long short‐term memory (LSTM) network.

Fractionalization of coset non-invertible symmetry and exotic Hall conductance
SciPost PhysicsWe investigate fractionalization of non-invertible symmetry in (2+1)D topological orders. We focus on coset non-invertible symmetries obtained by gauging non-normal subgroups of invertible $0$-form symmetries.

Dark matter and dark force in the type-I inert 2HDM with local U(1)H gauge symmetry [PDF]
, 2014 A bstractWe discuss dark matter (DM) physics in the Type-I inert two-Higgs-doublet model (2HDM) with local U(1)H Higgs gauge symmetry, which is assigned to the extra Higgs doublet in order to avoid the Higgs-mediated flavor problems. In this gauged inert

Conformal symmetry in quantum gravity
European Physical Journal C: Particles and FieldsWe study the problem of how to derive conformal symmetry in the framework of quantum gravity. We start with a generic gravitational theory which is invariant under both the general coordinate transformation (GCT) and Weyl transformation (or equivalently,

Weyl gauge-vector and complex dilaton scalar for conformal symmetry and its breaking [PDF]
, 2015 Instead of the scalar “dilaton” field that is usually adopted to construct conformally invariant Lagrangians for gravitation, we here propose a hybrid construction, involving both a complex dilaton scalar and a Weyl gauge-vector, in accord with Weyl’s ...
