This thesis discusses experimental studies with vapor cells containing rubidium (Rb) or cesium (Cs) atoms. Transitions in the atoms (D1 and D2 lines) are accessed using diode lasers. Experiments are performed at room ...

The thesis investigates the optical, photo-physical, and electrical properties of CdTe and HgCdTe nano- and micro-structures synthesized by hydrothermal/solvothermal technique. Application oriented studies like fluorescence ...

Despite the central role that Equilibrium thermodynamics has played in our understanding of many body systems, the underlying theoretical construct is strictly correct only in the ‘Thermodynamic Limit’. On the other hand, ...

Since the discovery of graphene, the field of 2D materials has garnered massive interest from a materials science, basic physics and device application point of view. This results from the diverse range of electronic and ...

We have studied the mixing of multiple forced passive scalars in 3D homogeneous and isotropic turbulence. The trends of the structure functions for a single scalar, although not very well resolved, seem to be similar to ...

Thermoelectric phenomena like the Seebeck and Peltier effects are known for more than two centuries with a wide range of applications. In 2008 Uchida et al. first demonstrated the phenomena called Spin Seebeck Effect (SSE) ...

X-ray crystallographic studies of designed peptides provide definitive proof of the success of a design strategy and yield essential structural information that can be utilized in the future design of biologically and ...

The successful exfoliation of graphene in 2004 ushered in the era of 2D van der Waals materials, paving the way for a wide variety of applications in the field of electronics, optoelectronics, sensors, catalysis, flexible ...

The primary goal of this thesis is to develop a light sheet based microscopy system that provides non-invasive images having high spatial and temporal resolution. The fluorescence microscopy has become an indispensable ...

The thermoelectric effect and the linear response theory is one of the most studied areas in condensed matter physics. In the last few years, the study of Van Der Waals heterostructure has become one of the most promising ...
