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 ...
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 ...
Investigation of Structural relaxation in IV - V -VI Chalcogenide glasses for Infrared applications
Chalcogenide glasses are well known for their application in infrared transmission and sensing. These
glasses are usually prepared by quenching the melt. The arrangement of atoms in the liquid state
gets arrested into ...
Superconducting qubit-based hybrid devices
Quantum technology has potential applications in many areas of science and engineering. Recently, there has been significant progress in developing hybrid quantum devices using a superconducting qubit platform. The hybrid ...
Phonon anomalies in pyrochlores and 2D materials under extreme conditions: Insights from Raman spectroscopic studies
In solids, electrons do not behave as separate particles but instead interact intensely
to form quasiparticles, which couple with other quasiparticles such as phonon,
plasmon, and exciton to generate emergent quantum ...
Investigation of twisted bilayer graphene using electrical and thermoelectric transport
The ability to tune the twist angle between di erent layers of two-dimensional materials has opened up a new
dimension to band engineering in van der Waals (vdW) heterostructures. By taking advantage of the formation
of ...
Detection of charge-neutral modes to spin-wave excitations in graphene quantum Hall, and periodic magnetic field effect on Dirac electrons
In the quantum Hall (QH) regime, the electrical transport happens along the downstream chiral edge modes (dictated by the external magnetic field) while the bulk remains a vanilla insulator. However, it has been theoretically ...
Magnetically powered helical nanoswimmers
From flocking birds to migrating cells, ‘active matter’ is ubiquitous in the natural world. Almost all known life forms are based on self-propelled entities working collectively to create large-scale structures, networks, ...
Probing the inflationary universe and reheating with primordial black holes and induced gravitational wave background
The direct observational test for the earliest phase of our universe comes from cosmic microwave background (CMB) radiation, which can only probe up to the recombination era. The only definitive event during the pre-recombination ...
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 ...
