Magic-wavelength matter-wave interferometry with optical clock states
Jianing Li, Swarup Das, Xinyuan Ma +4
Optical clocks and atom interferometers provide complementary ways to measure time, motion and gravity. Combining these capabilities requires matter-wave beam splitters that manipu…
Contact cosmetic surgery on Legendrian knots in integer homology sphere -spaces
Apratim Chakraborty, Swarup Kumar Das, Tanushree Shah
We extend the study of contact cosmetic surgeries to Legendrian knots in integer homology sphere L-spaces . We prove that the contact cosmetic surgery conjecture holds for all non-…
Magic wavelength at 477 nm for the strontium clock transition
Xinyuan Ma, Swarup Das, David Wilkowski +1
We report the experimental measurement of a magic wavelength at 476.82362(8) nm for the 88Sr clock transition. The magic wavelength is determined through AC-Stark shift spectroscop…
A spanning tree model for Khovanov homology, Rasmussen's s-invariant and exotic discs in the -ball
Aninda Banerjee, Apratim Chakraborty, Swarup Kumar Das
The checkerboard coloring of knot diagrams offers a graph-theoretical approach to address topological questions. Champanerkar and Kofman defined a complex generated by the spanning…
A spanning tree model for chromatic homology
Aninda Banerjee, Apratim Chakraborty, Swarup Kumar Das +1
After the discovery of Khovanov homology, which categorifies the Jones polynomial, an analogous categorification of the chromatic polynomial, known as chromatic homology, was intro…
