Decoherence and the Reemergence of Coherence From a Superconducting "Horizon''
Eric J. Sung, Charles A. Stafford
In a recent paper [arXiv:2205.06279], Danielson et al. demonstrated that the mere presence of a black hole causes universal decoherence of quantum superpositions (dubbed the DSW de…
Emergence of the 2nd Law in an Exactly Solvable Model of a Quantum Wire
Marco A. Jimenez-Valencia, Charles A. Stafford
As remarked by Boltzmann, the Second Law of Thermodynamics is notable for the fact that it is readily proved using elementary statistical arguments, but becomes harder and harder t…
Entropy Flow at the Quantum Limit
Marco A. Jimenez-Valencia, Parth Kumar, Yiheng Xu +2
Thermal management is a key challenge, both globally and microscopically in integrated circuits and quantum technologies. The associated heat flow has been understood since t…
Thermodynamics of a Quantum Subsystem
Parth Kumar, Charles A. Stafford
Several prior attempts to formulate the Laws of Thermodynamics for a small region within a larger quantum system have led to inconsistencies and unexplained infinities. The entropy…
Work Sum Rule for Open Quantum Systems
Parth Kumar, Caleb M. Webb, Charles A. Stafford
A key question in the thermodynamics of open quantum systems is how to partition thermodynamic quantities such as entropy, work, and internal energy between the system and its envi…
Persistent versus dissipative Peltier effect in a topological quantum thermocouple
Marco A. Jimenez-Valencia, Yiheng Xu, Charles A. Stafford
The Aharonov-Bohm (AB) effect on the thermoelectric properties of three-terminal quantum devices is investigated. Thermodynamic relations among the linear-response coefficients of…
