Quantum oscillation in band insulators and properties of non-equilibrium steady states in disordered insulators
Starting with the experiment on Kondo insulator SmB6 , which shows 1/B-periodic oscillations despite the absence of gapless electronic excitations in bulk, the candidate insulators showing quantum oscillation (QO) are on ... -
Realization of magnetic Weyl semimetallic phase in pyrochlore iridates thin films
Weyl semimetals (WSMs) are characterized by two linear non-degenerate band crossing inside the bulk of the Brillouin zone. The spin-degeneracy of the bands can be lifted by either broken inversion symmetry or broken ... -
Realization of Type-II Dirac Semi-metal in NiTe2 using Structural, Electrical and Magnetic Investigation
Dirac semimetal (DSM) is a topological semi-metal with a fourfold degenerate linear band crossing in the bulk, in the presence of time-reversal symmetry and inversion symme- try, exhibiting nontrivial spin-momentum locking ... -
Spectroscopic study of emitter assemblies coupled to Plasmonic nano-cavities and metamaterials
The plasma oscillations of noble metals as silver and gold are well understood from the free electron model of metals. In the past two decades, due to the availability of various physical and chemical fabrication methods ... -
Statistics of Conductance Fluctuations in 2D systems
Study of 2D materials is interesting due to the various phase transitions observed in these materials. I shall present the results obtained in the study of phase transi tions in three different 2D material systems – ... -
Structural and Thermoelectric Studies of Sb2Te3 and Bi2Te3 Based Chalcogenide Alloys and Nanocomposites
Thermoelectricity is one of the potential solutions for the rapidly increasing energy demand. Thermoelectric generators can turn waste heat into usable energy. Due to their effectiveness in the 300 K to 500 K temperature ... -
Structural signatures of relaxation mechanisms in glass forming and devitrifying colloidal suspensions
Connecting macroscopic behavior of matter to the microscopic interactions is the central goal of condensed matter physics. Yet, achieving such a challenging goal in atomic and molecular systems would require tracking all ... -
Ultrastrong coupling in a cavity-electromechanical device
Cavity optomechanics is a field that explores the interaction between light and motion of matter via radiation pressure force. Such systems mainly consist of an optical/microwave cavity coupled to a mechanical resonator. ...
