X-symbols for non-Abelian symmetries in tensor networks

Physical Review Research, 2020
The full exploitation of non-Abelian symmetries in tensor network states (TNSs) derived from a given lattice Hamiltonian is attractive in various aspects.

Three-dimensional non-Abelian Bloch oscillations and higher-order topological states

Communications Physics, 2023
Recently, higher-order topological insulators (HOTIs) have been introduced, and were shown to host topological corner states under the theoretical framework of Benalcazar-Bernevig-Hughes.

Countable networks on Malykhin's maximal topological group

Applied General Topology, 2023
We present a solution to the following problem: Does every countable and non-discrete topological (Abelian) group have a countable network with infinite elements?

Abstract structure of unitary oracles for quantum algorithms [PDF]

Electronic Proceedings in Theoretical Computer Science, 2014
We show that a pair of complementary dagger-Frobenius algebras, equipped with a self-conjugate comonoid homomorphism onto one of the algebras, produce a nontrivial unitary morphism on the product of the algebras.

Elementary abelian covers of the Wreath graph W (3, 2) and the Foster graph F26A

AKCE International Journal of Graphs and Combinatorics, 2023
Arc-transitive and edge-transitive graphs are widely used in computer networks. Therefore, it is very useful to introduce and study the properties of these graphs.

Chemical bonds of two vortex species with a generalized Josephson term and arbitrary charges

Journal of High Energy Physics, 2020
We consider the Abelian-Higgs model with two complex scalar fields and arbitrary positive integer charges with the addition of a higher-order generalization of the Josephson term. The theory possesses vortices of both local and global variants.

Finite-density phase diagram of a $(1+1)-d$ non-abelian lattice gauge theory with tensor networks [PDF]

Quantum, 2017
We investigate the finite-density phase diagram of a non-abelian $SU(2)$ lattice gauge theory in $(1+1)$-dimensions using tensor network methods. We numerically characterise the phase diagram as a function of the matter filling and of the matter-field ...

String-net formulation of Hamiltonian lattice Yang-Mills theories and quantum many-body scars in a nonabelian gauge theory

Journal of High Energy Physics, 2023
We study the Hamiltonian lattice Yang-Mills theory based on spin networks that provide a useful basis to represent the physical states satisfying the Gauss law constraints. We focus on SU(2) Yang-Mills theory in (2 + 1) dimensions.

Scaling properties of cosmological axion strings

Physics Letters B, 2019
There has been recent interest in the evolution and cosmological consequences of global axionic string networks, and in particular in the issue of whether or not these networks reach the scale-invariant scaling solution that is known to exist for the ...

Charge and Spin Sharpening Transitions on Dynamical Quantum Trees [PDF]

Quantum
The dynamics of monitored systems can exhibit a measurement-induced phase transition (MIPT) between entangling and disentangling phases, tuned by the measurement rate.
