Virtual temperatures as a key quantifier for passive states in quantum thermodynamic processes
Sachin Sonkar, Ramandeep S. Johal
We analyze the role of virtual temperatures for passive quantum states through the lens of majorization theory. A mean temperature over the virtual temperatures of adjacent energy…

Energy-gap modulation and majorization in three-level quantum Otto engine
Sachin Sonkar, Ramandeep S. Johal
A three-level quantum system having two energy gaps presents a nontrivial working medium for a quantum heat engine. Our focus lies in understanding the constraints on the ability t…

Spins-based Quantum Otto Engines and Majorisation
Sachin Sonkar, Ramandeep S. Johal
The concept of majorisation is explored as a tool to characterize the performance of a quantum Otto engine in the quasi-static regime. For a working substance in the form of a spin…
