Microorganisms are omnipresent in our life and the environment, such as microbes in the gut, spermatozoa in reproductive organs, algae and protozoa in the aquatic ecosystem, and bacterial colonization and infection. ...

Entanglement entropy is emerging as a useful quantity to study critical phenomena in quantum systems, black holes physics, and holography. In this presentation, we discuss entanglement properties of gauge theories and ...

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 ...

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 ...

Tokamak and stellarator are two leading contenders in the quest to achieve nuclear fusion from magnetically-confined plasmas. They differ in terms of magnetic field structure in the toroidal direction. Irrespective of the ...

The quest to understand our Universe’s fundamental particles and their interactions has led us to the Standard Model (SM) of particle physics. Despite successfully explaining the weak, electromagnetic, and strong ...

Magnetism and magnetism-driven phenomena have always remained a central theme of modern condensed matter physics. Conventional magnetic transition, such as para magnetic to ferromagnetic phase, involves symmetry breaking ...

Spin transport across magnetic insulator/heavy metal (MI/HM) interfaces has been a topic of interest in spintronics. The spin Seebeck effect (SSE) and spin Hall magnetoresistance (SMR) are two phenomena that have ...

In perturbation theory, predictions from theories like Quantum Chromodynamics (QCD) are obtained by evaluating Feynman diagrams to high orders. Such calculations for re sults for various processes are already available ...

In this thesis, we develop new methods for the S matrix bootstrap in the context of 2-2 scattering amplitudes and four-point correlators in conformal field theories (CFTs). For 2-2 scattering in quantum field theories, ...
