Observation of Crystalline Nonlocal Volume Plasmon Waves
Sathwik Bharadwaj, Makoto Schreiber, Jungho Mun +6
In plasmonics, nonlocal effects arise when the material response to optical excitations is strongly dependent on the spatial correlations of the excitation. It is well known that a…
Quantum Imaging of Photonic Spin Texture in an OAM Beam with NV Centers in Diamond
Shoaib Mahmud, Wei Zhang, Farid Kalhor +2
Photonic spin texture (PST), the spatial distribution of the spin angular momentum (SAM) of light, is connected to unique properties of light, such as optical skyrmions and topolog…
What are the quantum commutation relations for the total angular momentum of light?
Pronoy Das, Li-Ping Yang, Zubin Jacob
The total angular momentum of light has received attention for its application in a variety of phenomena such as optical communication, optical forces and sensing. However, the qua…
Quantum theory of orbital angular momentum in spatiotemporal optical vortices
Pronoy Das, Sathwik Bharadwaj, Zubin Jacob
Spatiotemporal Optical Vortices (STOVs) are structured electromagnetic fields propagating in free space with phase singularities in the space-time domain. Depending on the tilt of…
