Direct observation of the effects of spin dependent momentum of light in optical tweezers
Debapriya Pal, Subhasish Dutta Gupta, Nirmalya Ghosh +1
We demonstrate that tight focusing of a circularly polarized Gaussian beam in optical tweezers leads to spin-momentum locking - with the transverse spin angular momentum density be…
Cavity Enhanced Interference of Orthogonal Modes in a Birefringent Medium
Kiran Kolluru, Subhasish Dutta Gupta
Interference of orthogonal modes in a birefringent crystal is known to lead to interesting physical effects (Solli et al., Phys. Rev. Lett. 91, 143906 (2003)). In this paper we sho…
Unitary quantum phase operators for bosons and fermions: A model study on quantum phases of interacting particles in a symmetric double-well potential
Biswajit Das, Bitan Ghosal, Subhasish Dutta Gupta +1
We introduce unitary quantum phase operators for material particles. We carry out a model study on quantum phases of interacting bosons in a symmetric double-well potential in term…
