Magnonic Otto thermal machine

N Vidal-Silva, FJ Peña, RE Troncoso, P Vargas - Physical Review Research, 2024 - APS
We propose a quasistatic magnon-based Otto thermal machine in two-dimensional (2D)
magnetic insulators. The thermodynamical cycles are engineered by exposing a magnon …

Using non-Markovian dynamics in effective-negative-temperature-based transient quantum Otto engines

A Maity, A Ghoshal - Physical Review A, 2024 - APS
We demonstrate that the efficiency of effective-negative-temperature-based quantum Otto
engines, already known to outperform their traditional counterparts operating with positive …
