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

Fractional skyrme lines in ferroelectric barium titanate
Physical Review ResearchWe predict a topological defect in perfectly screened ferroelectric barium titanate which we call a skyrme line. These are linelike objects characterized by skyrmionic topological charge.

Model Realization and Numerical Studies of a Three-Dimensional Bosonic Topological Insulator and Symmetry-Enriched Topological Phases [PDF]
, 2014 We study a topological phase of interacting bosons in (3+1) dimensions which is protected by charge conservation and time-reversal symmetry. We present an explicit lattice model which realizes this phase and which can be studied in sign-free Monte Carlo ...

Trions in 1+1 dimensions [PDF]
, 2010 We consider an Abelian BF-Higgs theory with Nf=2 Higgs fields in 1+1 dimensions. We derive a new BPS-like bound and find topological solitons with tri-charges (topological charge, Q-charge and electric charge).

On topological charge carried by nexuses and center vortices
, 2001 In this paper we further explore the question of topological charge in the center vortex-nexus picture of gauge theories. Generally, this charge is locally fractionalized in units of 1/N for gauge group SU(N), but globally quantized in integral units. We

Topology in the SU(Nf) chiral symmetry restored phase of unquenched QCD and axion cosmology [PDF]
, 2016 We investigate the topological properties of unquenched $QCD$ on the basis of numerical results of simulations at fixed topological charge, recently reported by Borsanyi et al..

Tunable spin-charge conversion through topological phase transitions in zigzag nanoribbons [PDF]
, 2016 We study spin-orbit torques and charge pumping in magnetic quasi-one dimensional zigzag nanoribbons with hexagonal lattice, in the presence of large intrinsic spin-orbit coupling. Such a system experiences topological phase transition from a trivial band

Exchange-biasing topological charges by antiferromagnetism [PDF]
Nature Communications, 2018 AbstractGeometric Hall effect is induced by the emergent gauge field experienced by the carriers adiabatically passing through certain real-space topological spin textures, which is a probe to non-trivial spin textures, such as magnetic skyrmions. We report experimental indications of spin-texture topological charges induced in heterostructures of a ...

Ergodic sampling of the topological charge using the density of states
European Physical Journal C: Particles and Fields, 2021 In lattice calculations, the approach to the continuum limit is hindered by the severe freezing of the topological charge, which prevents ergodic sampling in configuration space.

Measurement-Only Topological Quantum Computation via Anyonic Interferometry
, 2008 We describe measurement-only topological quantum computation using both projective and interferometrical measurement of topological charge. We demonstrate how anyonic teleportation can be achieved using "forced measurement" protocols for both types of ...
