Z2 Gauge Theory
Z2 Gauge Theory. 2lattice gauge theory and deconfined criticality with an emergent u(1) gauge field 4. In the language of the lattice gauge theory, one of the couplings controls the “stiffness”

Since the ising gauge field mediates attraction, when coupled to fermionic matter it leads to formation of an exotic superfluid state. 2lattice gauge theory and topological order 2. Such gauge theories in higher dimensions are interesting in condensed matter physics and are believed to describe frustrated quantum magnets and spin liquid phases of materials [19] , [20] and have also been studied by.
Our Model Is A Simple One Dimensional Z 2 Lattice Gauge Theory Which Contains Massless Fermions Interacting With A Z 2 Lattice Gauge Fields.
The main idea is to switch from integer arithmetics (ℤ) to binary one (ℤ2) for the electric flux through lattice links. In particular limits the model reduces to (i) pure $\mathbb{z}_2$ even and odd gauge theories, (ii) free fermions in a static background of. Some of this material can be found in the usual quantum
We Will Use The Notation U Μ ≡ Τ Μ,Withτ Μ = ±1.
The partition function of the ising gauge theory is z. Such gauge theories in higher dimensions are interesting in condensed matter physics and are believed to describe frustrated quantum magnets and spin liquid phases of materials [19] , [20] and have also been studied by. N= (n 0;n 1;n 2), 0 n 0 We consider the partition function [1] ze z 2 = x f˙ ijg= 1 exp he z 2 =t he z 2 = k x (y ij)2 ˙ ij; In the quantum language, these two couplings allow us to separately control the masses of both e and m excitations. Quantum eld theory, dating from the mid 1970s and early 1980s, and underlies large swathes of current research. Since the ising gauge field mediates attraction, when coupled to fermionic matter it leads to formation of an exotic superfluid state. Φstr = φstr , φstr = φstr • the hamiltonian to enforce the dancing rules: In the language of the lattice gauge theory, one of the couplings controls the “stiffness” The ising* confinement transition 3. 2gauge field + fermionic/bosonic spinons • if matter is gapped, can be integrated out → reduces to pure gauge theory (e.g., topological phases) • if matter is. Requires gauge fixing to have an integration measure that sumsovergauge classes of configurations.It Actually Occurs In The Exact Solution.
In A Recent Collaboration With Lmu Munich And The University Of Queensland (Australia) We Have Proposed A New Analog Quantum Simulation Scheme For Z2 Lattice Gauge Theories Coupled To Dynamical Matter.
