【报告摘要】： This lecture explores the operational principles of quantum thermal machines, bridging fundamental concepts with current research challenges. I will begin by presenting results from my Master’s research on quantum refrigerators, specifically discussing the concept of negative spin temperatures and the role of fermionic reservoirs. Building on these foundations, I will introduce my ongoing Ph.D. investigation into the statistics of work and heat using the Two-Measurement Scheme—an approach that remains an open challenge for specific configurations. We will also discuss the efficiency of collective thermal machines driven by non-equilibrium reservoirs.

【报告人简介】：Gabriella Goncalves Damas, a researcher specializing in Quantum Thermodynamics and Quantum Optics, holding a Master’s degree from the Federal University of Goiás, interested in quantum refrigeration and negative temperature regimes. Currently, her doctoral research focuses on two main fronts: the calculation of work/heat fluctuations using the two-measurement scheme in non-equilibrium systems, and the development of effective Hamiltonians for high-fidelity quantum control in strongly coupled systems.
