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

, 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 ...

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

, 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 ...

ON TOPOLOGICAL CHARGED BRANEWORLD BLACK HOLES [PDF]

Modern 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.

Generation of terahertz vector beam bearing tailored topological charge

APL Photonics, 2023
Optical vector beams have great potential in many applications, for example optical tweezers, information transmission and processing, laser surface structuring, particle acceleration, and vortex dichroism spectroscopy. However, the reported vector beams

Topological influence and back-action between topological excitations

, 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

Topological Charge Membranes in 2D and 4D Gauge Theory [PDF]

, 2004
Local topological charge structure in the 2D CP(N-1) sigma models is studied using the overlap Dirac operator. Long-range coherence of topological charge along locally 1D regions in 2D space-time is observed.

Helicity and topological charge tunable optical vortex based on a Hermite-Gaussian beam dynamically controlled folded-cavity resonator

Frontiers in Physics, 2023
Helicity and topological charge are two important characteristic parameters for vortex beam applications, including optical communications, optical manipulation and material processing, etc.

Electroweak quark-lepton symmetry and weak topological-charge confinement in the Standard Model with Dirac neutrinos

, 2007
The standard electroweak model with Dirac neutrinos is extended by way of the principles of electroweak quark-lepton symmetry and weak topological-charge confinement to account for quark-lepton charge relations which, if not accidental, are indicative of
