Breaking of Time Translation Symmetry and Ergodicity, and Entropy decrease in a Continuous Time Crystal Driven by Nonreciprocal Optical Forces
Tongjun Liu, Venugopal Raskatla, Jinxiang Li +2
Nonreciprocal nonequilibrium process are attracting growing interest in sociology, animal behaviour, chemistry, and nanotechnology, and may have played a role in the origin of life…
Astigmatic Speckle-learned OAM Shift Keying and OAM Multiplexing
Trishita Das, Manas Ranjan Pandit, Venugopal Raskatla +2
Orbital angular momentum (OAM)-carrying beams have gained significant attention in recent years due to their unique properties and potential to improve spectral efficiency and data…
Machine learning meets Singular Optics: Speckle-based Structured light demultiplexing
Venugopal Raskatla, Purnesh Singh Badavath, Vijay Kumar
In this paper, the advancements in structured light beams recognition using speckle-based convolutional neural networks (CNNs) have been presented. Speckle fields, generated by the…
Continuous Space-Time Crystal State Driven by Nonreciprocal Optical Forces
Venugopal Raskatla, Tongjun Liu, Jinxiang Li +2
Continuous time crystals (CTCs) - media with broken continuous time translation symmetry - are an eagerly sought state of matter that spontaneously transition from a time-independe…
