Topological Amplification in Photonic Lattices [PDF]
Physical Review Letters, 2019 We present a characterization of topological phases in photonic lattices. Our theory relies on a formal equivalence between the singular value decomposition of the non-Hermitian coupling matrix and the diagonalization of an effective Hamiltonian. By means of that mapping we unveil an application of topological band theory to the description of quantum ...

Observation of strong spin-orbit couplings in plasmonic spin-twistronics topological lattices [PDF]
Nature CommunicationsTwistronics is based on the control of the relative twist angle between the two layers of two-dimensional (2D) material in a moiré superlattice. Manipulating the twist angle enables controlling a variety of nontrivial properties, making twistronics a ...

Space and space-time topologies in a type-II hyperbolic lattice [PDF]
Nature CommunicationsRecent breakthroughs in hyperbolic lattices have expanded the study of topological phases of matter from Euclidean to non-Euclidean spaces. However, prior work has mostly focused on static spatial topological states at the single outer edge of type-I ...

All‐Bands‐Flat Floquet Topological Photonic Insulators with Microring Lattices
Advanced Photonics ResearchCoupled microring lattices are versatile photonic systems that can be used to realize various topological phases of matter. In two‐dimensional (2D) microring lattices, the periodic and unidirectional circulation of light in each microring gives rise to a

On generalized topological molecular lattices [PDF]
Sahand Communications in Mathematical Analysis, 2018 In this paper, we introduce the concept of the generalized topological molecular lattices as a generalization of Wang's topological molecular lattices, topological spaces, fuzzy topological spaces, L-fuzzy topological spaces and soft topological spaces.

Some non-standard quasivarieties of lattices [PDF]
Қарағанды университетінің хабаршысы. Математика сериясы, 2023 The questions of the standardness of quasivarieties have been investigated by many authors. The problem "Which finite lattices generate a standard topological prevariety?" was suggested by D.M. Clark, B.A. Davey, M.G. Jackson and J.G. Pitkethly in 2008.
