Designing Robust Quantum Refrigerators in Disordered Spin Models

  title={Designing Robust Quantum Refrigerators in Disordered Spin Models},
  author={Tanoy Kanti Konar and Srijon Ghosh and Amit Kumar Pal and Aditi Sen De},
We explore a small quantum refrigerator in which the working substance is made of paradigmatic nearest neighbor quantum spin models, the XY Z and the XY model with Dzyaloshinskii-Moriya interactions, consisting of two and three spins, each of which is in contact with a bosonic bath. We identify a specific range of interaction strengths which can be tuned appropriately to ensure a cooling of the selected spin in terms of its local temperature in the weak coupling limit. Moreover, we report that… Expand

Quantum Phase Transitions
We give a general introduction to quantum phase transitions in strongly-correlated electron systems. These transitions which occur at zero temperature when a non-thermal parameter $g$ like pressure,Expand
Physical implementations of quantum absorption refrigerators
Absorption refrigerators are autonomous thermal machines that harness the spontaneous flow of heat from a hot bath into the environment in order to perform cooling. Here we discuss quantumExpand
