Quantum Phases of a Spin-1 Bose Gas in an Optical Lattice: A Focus on Mean Field and Perturbative Approaches
Nabi, Sk Noor (2018)
The primary motivation is to explore various quantum phases, such as, Mott insulator (MI), superfluid (SF) and the density ordered phases in the SBHM for either sign (positive or negative) of the spin dependent interaction potential...

Self-organized criticality on complex networks: Sandpile model, Scaling and Universality
Bhaumik, Himangsu (2018)
Sandpile is a generic model to study self-organized criticality (SOC) which provides a general mechanism for the emergence of complex behavior in many physio-chemical processes. On the other hand, the topology of many interacting systems...

Magnetic properties of single-layer and trilayer structured CoFeB based magnetic thin films
Gayen, Anabil (2018)
Spintronics is the study of phenomena related to the spin of electrons and of devices that take advantage of the spin of the electron along with its charge. In contrast to conventional electronics, which is limited to transport and manipulation of electric charges ...

Ground-state Cooling and Photon Antibunching in Cavity Optomechanical Systems
Sarma, Bijita (2018)
Cavity optomechanics aims at understanding the radiation pressure induced interaction between photons and mechanical motion in a cavity. The radiation pressure force, arising due to the momentum carried by light, can displace a movable ...

Investigations on magnetic and semiconducting nanomaterials prepared by sol-gel and electrospinning routes
Das, Arnab Kumar (2018)
Low dimensional or nanostructured materials offer several advantages over their bulk counterparts due to quantum confinement along one or more dimensions. As a consequence, it is possible to tailor their properties and...

Ab initio molecular dynamics studies of structural, dynamical and spectroscopic aspects of waterborne selenium and arsenic species
Borah, Sangkha (2018)
Water contamination is a global issue in most parts of the world. The present thesis deals with the microscopic nature of interaction of two major water contaminants, namely selenium (Se) and arsenic (As), restricting largely...
