Polariton lasers emit coherent monochromatic light through a spontaneous emission
process. As a rare example of a system in which Bose–Einstein condensation and …

<? pag\vskip-16pt?> Harnessing linear and angular momenta of light is one of the
cornerstones in modern optics and has found tremendous applications in optical circuits …

In recent times, the optical-analogous skyrmions, topological quasiparticles with
sophisticated vectorial structures in light, have received an increasing amount of interest …

Skyrmions are topologically stable quasiparticles that have been predicted and
demonstrated in quantum fields, solid-state physics and magnetic materials, but only …

Metasurfaces are subwavelength structured thin films consisting of arrays of units that allow
the control of polarization, phase, and amplitude of light over a subwavelength thickness …

Symmetry and topology govern many electronic, magnetic, and photonic phenomena in
condensed matter physics and optics, resulting in counterintuitive skyrmion, meron, and …

Topological wave structures—phase vortices, skyrmions, merons, etc.—are attracting
enormous attention in a variety of quantum and classical wave fields. Surprisingly, these …

Topological physics relies on Hamiltonian's eigenstate singularities carrying topological
charges, such as Dirac points, and–in non-Hermitian systems–exceptional points (EPs) …

Skyrmions endowed with topological protection have been extensively investigated in
various platforms including magnetics, ferroelectrics, and liquid crystals, stimulating …

This Letter proposes a family of structured light, called bimeronic beams, that characterize
topological structures of bimeron (the quasiparticle homeomorphic to skyrmion). The …
