Precision Measurement of the Saturation Intensity in Rubidium at 420 nm

Shivam Sinha, Sumit Achar, Sankar Satheesh +1

The 5S1/2​→6P3/2​ transition of rubidium at 420 nm is a promising candidate for a portable warm-vapor all-optical atomic clock. Despite recent precision spectro…

Generalized I^±-Observational Entropy

Shivam Sinha, Nripendra Majumbdar, S. Aravinda

Traditional measures of entropy, like the Von Neumann entropy, while fundamental in quantum information theory, are insufficient when interpreted as thermodynamic entropy due to th…
