Cold Atoms in Space: Community Workshop Summary and Proposed Road-Map
Ivan Alonso, Cristiano Alpigiani, Brett Altschul +246
We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportu…
Machine learner optimization of optical nanofiber-based dipole traps for cold Rb atoms
Ratnesh K. Gupta, Jesse L. Everett, Aaron D. Tranter +4
In two-color optical nanofiber-based dipole traps for cold alkali atoms, the trap efficiency depends on the wavelength and intensity of light in the evanescent field, and the initi…
Temperature increases and thermoplastic microstructural evolution in adiabatic shear bands in a high-strength and high-toughness 10 wt.% Ni steel
Sung-Il Baik, Ratnesh K. Gupta, K. Sharvan Kumar +1
A 10 wt.% nickel-steel has been developed for high pressures and low-temperature applications, due to its high strength, excellent toughness, and low ductile-to-brittle transition…
Observation of the Rb to electric quadrupole transition at 516.6 nm mediated via an optical nanofibre
Tridib Ray, Ratnesh K. Gupta, Vandna Gokhroo +4
Light guided by an optical nanofibre can have a very steep evanescent field gradient extending from the fibre surface. This can be exploited to drive electric quadrupole transition…
Magnetization study to probe the effect of N2+ irradiation on Fe/Co bilayers
Harkirat Singh, Ratnesh Gupta, Ashish Khandelwal +1
Fe/Co bilayers were made using ion beam sputtering and then were subjected to nitrogen-ion irradiation to explore the influence of irradiation on their magnetic properties. Magneti…
Probing the dynamics of an optically trapped particle by phase sensitive back focal plane interferometry
Basudev Roy, Sambit Bikas Pal, Arijit Haldar +3
The dynamics of an optically trapped particle are often determined by measuring intensity shifts of the back-scattered light from the particle using position sensitive detectors. W…
