DESCRIPTION:Experimental Quantum Thermodynamics using Nuclear Magnetic Resonance\n\nProfessor Dawei Lu\, SUSTech\n\nAbstract: \n\nClassical thermodynamics studies macroscopic systems. In small-particle systems far from the thermodynamic limit\, many concepts and issues in classical thermodynamics need to be redefined and explored due to the influence of quantum effects\, gradually forming the emerging field of quantum thermodynamics. With the development of quantum information technology\, many quantum systems can now be precisely controlled\, providing an ideal platform for experimental research in quantum thermodynamics. In particular\, as a highly controllable room-temperature spin ensemble system\, nuclear magnetic resonance (NMR) offers unique advantages in the study of quantum thermodynamics. In this talk\, I will first briefly review the basic principles of NMR and spin control techniques. Then\, by utilizing two different quantum resources\, namely indefinite causal order and three-body interactions\, we can construct quantum versions of working substances and implement refrigeration cycles. Finally\, I will present experimental results demonstrating a "quantum refrigerator with indefinite causal order" and a "self-contained quantum refrigerator" using NMR spin ensembles. \n\nLocation \n\nQNC 0101
