On the First Law of Thermodynamics in Time-Dependent Open Quantum Systems
Parth Kumar, Charles A. Stafford
How to rigorously define thermodynamic quantities such as heat, work, and internal energy in open quantum systems driven far from equilibrium remains a significant open question in…
The third law of thermodynamics in open quantum systems
Abhay Shastry, Yiheng Xu, Charles A. Stafford
We consider open quantum systems consisting of a finite system of independent fermions with arbitrary Hamiltonian coupled to one or more equilibrium fermion reservoirs (which need…
Scanning Tunneling Thermometry
Abhay Shastry, Sosuke Inui, Charles A. Stafford
Temperature imaging of nanoscale systems is a fundamental problem which has myriad potential technological applications. For example, nanoscopic cold spots can be used for spot coo…
Emergence of Fourier's law of heat transport in quantum electron systems
Sosuke Inui, Charles A. Stafford, Justin P. Bergfield
The microscopic origins of Fourier's venerable law of thermal transport in quantum electron systems has remained somewhat of a mystery, given that previous derivations were forced…
Local entropy of a nonequilibrium fermion system
Charles A. Stafford, Abhay Shastry
The local entropy of a nonequilibrium system of independent fermions is investigated, and analyzed in the context of the laws of thermodynamics. It is shown that the local temperat…
Temperature and voltage measurement in quantum systems far from equilibrium
Abhay Shastry, Charles A. Stafford
We show that a local measurement of temperature and voltage for a quantum system in steady state, arbitrarily far from equilibrium, with arbitrary interactions within the system, i…
