Quaternion Weyl Transform and some uniqueness results
Rupak Kumar Dalai, Somnath Ghosh, R. K. Srivastava
In this article, we study the boundedness and several properties of the quaternion Wigner transform. Using the quaternion Wigner transform as a tool, we define the quaternion Weyl…
Spherical means on Métivier groups and support theorem
Rupak Kumar Dalai, Somnath Ghosh, R. K. Srivastava
Let be the space of continuous functions on the annulus in whose -twisted spherical mean, in the set up of the Métivier group, vanishes over…
Unbounded Weyl transform on the Euclidean motion group and Heisenberg motion group
Somnath Ghosh, R. K. Srivastava
In this article, we define Weyl transform on second countable type - locally compact group and as an operator on we prove that the Weyl transform is compact when…
Exploring Unconventional Features Of Light Dynamics In Aubrey-Andre-Harper Model Based Quasi-periodic Optical Lattices
Suman Dey, Nikhil Ranjan Das, Somnath Ghosh
We report an Aubrey-Andre-Harper (AAH) model based quasi-periodic lossless evanescently coupled waveguide lattice to study the unconventional physics of light localization. We pres…
Hosting exceptional points in 1D photonic bandgap waveguide for mode engineering
Sibnath Dey, Somnath Ghosh
We report a planar 1D photonic bandgap waveguide exhibiting four second-order exceptional points (EP2s). The interactions between the selective pairs of supported quasi-guided TE m…
