Excitons Enabled Topological Phase Singularity in a Single Atomic Layer.
ACS Nano, 2023The nontrivial and rigorous Heaviside phase jump behavior of phase singularities (PSs) empowers exotic topological modes and widely divergent nature compared to neighboring points, which has attracted great attention in condensed matter physics as well ...

Evolution and Nonreciprocity of Loss-Induced Topological Phase Singularity Pairs.
Physical Review Letters, 2021Singular behaviors are increasingly being found in structures supporting bound states in the continuum (BICs), while the nonreciprocity with spectral phase singularity has not been reported.

Resetting of mammalian respiratory rhythm: existence of a phase singularity.
American Journal of Physiology, 1986 The purpose of this study was to use topological methods of analysis to determine if a phase singularity exists for the neural respiratory oscillator.

Multidimensional phase singularities in nanophotonics
Science, 2021Exploiting light with a twist Light possesses several degrees of freedom that can be exploited to encode information. In addition to wavelength, amplitude, phase, polarization, and pulse length, light can also be structured into vortices.

Singular Anisotropic Double Phase Problems
Results in Mathematics, 2023Using variational techniques together with truncation, comparison and approximation methods, the authors establish the existence and multiplicity theorems for three classes of anisotropic Dirichlet double phase problems. Precisely, the principal differential operator is the sum of a \(p(\cdot)\)-Laplace operator and of a \(q(\cdot)\)-Laplace operator ...

Phase Unwrapping with Phase-Singularity Spreading
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006We propose a novel phase unwrapping method where we spread the singularity in phase map with fractional phase compensators. We find that the obtained digital elevation maps have higher quality than those obtained in conventional network programming method. In addition, the calculation cost is very small.
