Fundamental Limitations on the Reliabilities of Power and Work in Quantum Batteries
Brij Mohan, Tanmoy Pandit, Maciej Lewenstein +1
Quantum batteries, microscopic devices designed to address energy demands in quantum technologies, promise high power during charging and discharging processes. Yet their practical…
Enhancing the Performances of Autonomous Quantum Refrigerators via Two-Photon Transitions
Brij Mohan, Bijay Kumar Agarwalla, Manabendra Nath Bera
Conventional autonomous quantum refrigerators rely on uncorrelated heat exchange between the working system and baths via two-body interactions enabled by single-photon transitions…
Coherent heat transfer leads to genuine quantum enhancement in the performances of continuous engines
Brij Mohan, Rajeev Gangwar, Tanmoy Pandit +3
Conventional continuous quantum heat engines with incoherent heat transfer perform poorly as they exploit two-body interactions between the system and hot or cold baths, thus havin…
Causal and Non-Causal Revivals of Information: A New Regime of Non-Markovianity in Quantum Stochastic Processes
Francesco Buscemi, Rajeev Gangwar, Kaumudibikash Goswami +5
The study of information revivals, witnessing the violation of certain data-processing inequalities, has provided an important paradigm in the study of non-Markovian quantum stocha…
