Abstract: Optical bound states in the continuum (BICs) are exotic topological defects in photonic crystal slabs, carrying polarization topological vortices in momentum space. The topological vortex configurations not only topologically protect the infinite radiation lifetime of… read more here.

DOI: 10.1109/lawp.2018.2851438
Abstract: The connection between topology and nonreciprocity in photonic systems is reviewed. Topological properties such as Chern number, and momentum-space properties such as Berry phase and Berry connection, are used to explain backscattering immune edge states… read more here.

DOI: 10.3390/axioms11080405
Abstract: One recent and prolific direction in the development of fixed point theory is to consider an operator T:X→X defined on a metric space (X,d) which is an F—contraction, i.e., T verifies a condition of type… read more here.

DOI: 10.3390/sym12091542
Abstract: Generally, the linear topological spaces successfully generate Tychonoff product topology in lower dimensions. This paper proposes the construction and analysis of a multidimensional topological space based on the Cartesian product of complex and real spaces… read more here.
