Journal of Cardiovascular Development and Disease, 2023 This article is the third in our series dedicated to the analysis of cardiac myoarchitecture as a nematic chiral liquid crystal (NCLC). Previously, we introduced the concept of topological defects (disclinations) and focused on their visual ...

Vortex laser arrays with topological charge control and self-healing of defects
Nature Photonics, 2022 Geometric arrays of vortices found in various systems owe their regular structure to mutual interactions within a confined system. In optics, such vortex crystals may form spontaneously within a resonator.

Topological charge and black hole photon spheres [PDF]
Physical Review D, 2020 Black hole photon spheres or light rings are closely linked to astronomical phenomena, such as the gravitational waves and the shadow in spherically symmetric or axi-symmetric spacetime. In Cunha and Herdeiro [Phys. Rev. Lett.

Topological Blockade and Measurement of Topological Charge [PDF]
Physical Review Letters, 2013 The fractionally charged quasiparticles appearing in the 5/2 fractional quantum Hall plateau are predicted to have an extra non-local degree of freedom, known as topological charge. We show how this topological charge can block the tunnelling of these particles, and how such 'topological blockade' can be used to readout their topological charge.

Electrically charged topological solitons [PDF]
Nuclear Physics B, 2001 Two new families of T-Dual integrable models of dyonic type are constructed. They represent specific $A_n^{(1)}$ singular Non-Abelian Affine Toda models having U(1) global symmetry. Their 1-soliton spectrum contains both neutral and U(1) charged topological solitons sharing the main properties of 4-dimensional Yang-Mills-Higgs monopoles and dyons.

Chinese Optics Letters (COL), 2022 The resolution of the spatial light modulator (SLM) screen and the encoding algorithm of the computer-generated hologram are the primary limiting factors in the generation of large topological charge vortex beams.

Topological charge, spin, and heat transistor [PDF]
Physical Review B, 2021 Spin pumping consists in the injection of spin currents into a non-magnetic material due to the precession of an adjacent ferromagnet. In addition to the pumping of spin the precession always leads to pumping of heat, but in the presence of spin-orbital entanglement it also leads to a charge current.

Topological charge of a superposition of identical parallel single-ringed Laguerre-Gaussian beams
Компьютерная оптика, 2022 We study a superposition of several identical parallel single-ringed Laguerre-Gaussian beams. Both for the initial plane and for the far field, we show analytically and confirm numerically that if the weighting coefficients of the superposition are real ...

Topological Charges of Periodically Kicked Molecules
Physical Review Letters, 2023 We show that the simplest of existing molecules -- closed-shell diatomics not interacting with one another -- host topological charges when driven by periodic far-off-resonant laser pulses. A periodically kicked molecular rotor can be mapped onto a ''crystalline'' lattice in angular momentum space.

Higher topological charge and the QCD vacuum
Physical Review Research, 2020 It is shown that gauge field configurations with higher topological charge modify the structure of the QCD vacuum, which is reflected in its dependence on the CP-violating topological phase θ.
