Enhancing the spin-orbit torque efficiency in Pt/CoFeB/Pt based perpendicularly magnetized systems
Controlling and switching magnetization by the process of current-induced torque has a
considerable advantage in lower power consumption for a memory device and spin logic device
application. For a heavy metal (HM) / ...
Thermalization and its Relation to Localization, Conservation Laws and Integrability in Quantum Systems
(2018-07-26)
In this thesis, we have explored the commonalities and connections between different classes of quantum systems that do not thermalize. Specifically, we have (1) shown that localized systems possess conservation laws like ...
Search for Northern Hemisphere Rapidly Oscillating Ap stars
(Indian Institute of Science, 2005-04-20)
Rapidly oscillating Ap (roAp) stars are cool, magnetic, chemically peculiar A-F type stars which exhibit high frequency oscillations similar to that of the famous five minute oscillations of Sun. These oscillations are ...
Multiband Modelling and Radio Observations of Gamma Ray Burst Afterglows
The widely popular and successful standard fireball model for Gamma Ray Burst (GRB) afterglows is based on ultra-relativistic external shocks sweeping up matter around the explosion site to accelerate electrons up to GOV ...
