Is there solid-on-solid contact in a sphere-wall collision in a viscous fluid?

Sumit Kumar Birwa, G. Rajalakshmi, Rama Govindarajan +1

We study experimentally the collision between a sphere falling through a viscous fluid, and a solid plate below. It is known that there is a well-defined threshold Stokes number ab…

Quantum interference-enhanced deep sub-Doppler cooling of 39 K atoms in gray molasses

Dipankar Nath, R Kollengode Easwaran, G. Rajalakshmi +1

We report enhanced sub-Doppler cooling of the bosonic atoms of K facilitated by formation of dark states tuned for the Raman resonance in the configuration near the D1 t…

Accelerated Thermalisation of 39K atoms in a Magnetic Trap with Superimposed Optical Potential

Dipankar Nath, R Kollengode Easwaran, G. Rajalakshmi +1

We report the rapid accelerated thermalisation of Potassium 39 K atoms loaded in a magnetic trap, in the presence of a single dipole trap beam. More than an order of magnitude redu…

Precision studies of Casimir force and short-range gravity employing prototypes of interferometric gravitational wave detectors

G. Rajalakshmi, C. S. Unnikrishnan

We discuss experimental schemes to measure the Casimir force and short range forces from hypothetical modified gravity with unprecedented sensitivity using highly sensitive prototy…

Torsion Balance Investigation of the Casimir Effect

G. Rajalakshmi

The presence of finite energy in quantum vacuum has profound implications to physics at the microscopic and macroscopic levels. One of the direct consequences of vacuum energy is t…
