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…

Limiting distribution of periodic position measurements of a quantum harmonic oscillator
Arnab Acharya, Debapriya Pal, Soumitro Banerjee +1
We consider a particle in harmonic oscillator potential, whose position is periodically measured with an instrument of finite precision. We show that the distribution of the measur…

AEDGE: Atomic Experiment for Dark Matter and Gravity Exploration in Space
Yousef Abou El-Neaj, Cristiano Alpigiani, Sana Amairi-Pyka +129
We propose in this White Paper a concept for a space experiment using cold atoms to search for ultra-light dark matter, and to detect gravitational waves in the frequency range bet…
