Spin quantum heat engines with shortcuts to adiabaticity
B Çakmak, ÖE Müstecaplıoğlu - Physical Review E, 2019 - APS
We consider a finite-time quantum Otto cycle with single-and two spin-1/2 systems as its
working medium. To mimic adiabatic dynamics at a finite time, we employ a shortcut-to …

Certifying quantum signatures in thermodynamics and metrology via contextuality of quantum linear response
M Lostaglio - Physical Review Letters, 2020 - APS
I identify a fundamental difference between classical and quantum dynamics in the linear
response regime by showing that the latter is, in general, contextual. This allows me to …
