(2010-09-06)Studies on perovskite rare earth manganites of general formula R1-xAxMnO3 (where R is a trivalent rare earth ion such as La3+, Pr3+ etc. and A is a divalent alkaline earth ion such as Ca2+, Sr2+, Ba2+, have been a very ... -
Manipulating phonons and electrons in two-dimensional materials
Two-dimensional (2D) materials are one or few atoms thick layered materials. The interaction between the layers in their parent three-dimensional material is weak. Therefore, one can stack different 2D materials on top ... -
The Many Facets of Variabilities in X-ray Binaries
(2018-02-28)More than half a decade of X-ray astronomy with various balloon borne and space orbiting X-ray instruments, have led to discoveries and detailed studies of X-ray binaries. An important property of X-ray binaries is intensity ... -
Many-body classical chaos: A case study across thermal phase transitions and connection to quantum measurements
There has been enormous interest in understanding the emergence of thermal behavior in systems isolated from the environment, be it classical or quantum. For classical systems, it has been argued that chaos plays a vital ... -
Mass Spectrometric Studies of K39/K41 & Li7/Li6 abundance variations in synthetic and natural samples
