  • Work fluctuations in periodically driven chaotic systeMS 
    P, SRAVYA (2019-04)
    Fluctuation relations have been one of the recent discoveries that have helped us take a step in understanding how thermodynamics can be applied to small systems in the quantum regime. In this study, we investigate the ...
  • Thermodynamic Uncertainty Relation for Charge Transport – Multilevel Setup 
    VALECHA, BHAVESH (2021-06)
    The tremendous advances in technology achieved over the past few decades have made possible engineering thermoelectric devices at astonishingly small scales, scales at which we can no longer neglect the inherent fluctuations. ...
  • Universal bounds on fluctuations in thermal machines and thermal transport junctions 
    SARYAL, SUSHANT (Dept. of Physics, 2022-07)
    The second law of thermodynamics forbids the possibility of a perpetual machine of a second kind. It provides a universal upper bound on the efficiency of any thermal machine operating between two heat baths, famously known ...
  • Impact of dephasing probes on various incommensurate lattice models 
    GHOSH, BISHAL KUMAR (2023-05)
    This thesis aims to study quantum transport and quantum dynamics properties in one dimensional quasi-periodic lattice systems. In particular we aim here to understand the impact of external probes on both the steady state ...
  • Quantum Thermodynamics of non-Hermitian Otto Engines 
    DOSAJH, SHIVAM (2024-04)
    One of the fundamental axioms of quantum mechanics is that observables are self-adjoint or Hermitian operators in a complex Hilbert space. What started as a mathematical curiosity in the late 90s, theoretical investigations ...
  • Quantum Transport in 1D and Quasi-1D Lattice Systems 
    DHAWAN, ABHINAV (2024-05)
    This thesis aims to study quantum transport in one-dimensional and quasi one-dimensional lattice systems. The first part deals with non-interacting fermions showing long-range power-law decaying hopping on an open ...
