Abstract:
With the advancements of experimental techniques in quantum mechanical systems, it is now possible to probe and control a wide variety of quantum systems with ever increasing sizes and complexities. One can now use these experimental systems, like NV-centres, trapped atoms, NMR etc., to study the thermodynamic properties like heat, work and entropy in a wide range of quantum mechanical systems, giving way to the experimental realisation and investigation of the field of Quantum thermodynamics. Quantum thermodynamics tries to bridge the gap between two independent theories of physics: Quantum Mechanics and Thermodynamics. In this work I describe the experiments done in our lab using Nuclear Magnetic Resonance (NMR) spin Qubits, of varying sizes, to better understand the relationship between the above mentioned thermodynamic quantities in the quantum regime and their interplay with quantum correlations and quantum information. We also explore the recently discovered many-body thermodynamic property of Time crystals, and localization of entanglement
in some quantum-classical systems.
