Thermal Simulations, Open Boundary Conditions and Switches

open access: yesEPJ Web of Conferences, 2018
SU(N) gauge theories on compact spaces have a non-trivial vacuum structure characterized by a countable set of topological sectors and their topological charge. In lattice simulations, every topological sector needs to be explored a number of times which

Critical analysis of topological charge determination in the background of center vortices in SU(2) lattice gauge theory

open access: yes, 2012
We analyze topological charge contributions from classical SU(2) center vortices with shapes of planes and spheres using different topological charge definitions, namely the center vortex picture of topological charge, a discrete version of F\~{F} in the

Center Vortices, Nexuses, and Fractional Topological Charge [PDF]

open access: yes, 1999
It has been remarked in several previous works that the combination of center vortices and nexuses (a nexus is a monopole-like soliton whose world line mediates certain allowed changes of field strengths on vortex surfaces) carry topological charge ...

Coherent Topological Charge Structure in $CP^{N-1}$ Models and QCD

open access: yes, 2005
In an effort to clarify the significance of the recent observation of long-range topological charge coherence in QCD gauge configurations, we study the local topological charge distributions in two-dimensional $CP^{N-1}$ sigma models, using the overlap ...

Topological influence and back-action between topological excitations

open access: yes, 2014
Topological objects can influence each other if the underlying homotopy groups are non-Abelian. Under such circumstances, the topological charge of each individual object is no longer a conserved quantity and can be transformed to each other. Yet, we can

ON TOPOLOGICAL CHARGED BRANEWORLD BLACK HOLES [PDF]

open access: yesModern Physics Letters A, 2009
We study a class of topological black hole solutions in RSII braneworld scenario in the presence of a localized Maxwell field on the brane. Such a black hole can carry two types of charge, one arising from the extra dimension, the tidal charge, and the other from a localized gauge field confined to the brane.

Charge as a Topological Property in Three-Dimensional Time

open access: yesReports in Advances of Physical Sciences
This paper presents electric charge as a topological property emerging naturally from the three-dimensional temporal structure previously established.

Quantum simulation of topological Majorana bound states and their universal quantum operations using charge-qubit arrays [PDF]

open access: yes, 2015
Majorana bound states have been a focus of condensed matter research for their potential applications in topological quantum computation. Here we utilize two charge-qubit arrays to explicitly simulate a DIII class one-dimensional superconductor model ...

Anomalous multi-ramp fractional vortex beams with arbitrary topological charge jumps [PDF]

open access: yes, 2020
Traditional fractional vortex beams are well-known "jump" beams: that is, their net topological charge jumps by unity as the effective topological charge of the source passes a half-integer value.
