Black-hole powered quantum coherent amplifier
Avijit Misra, Pritam Chattopadhyay, Anatoly Svidzinsky +2
Atoms falling into a black hole (BH) through a cavity are shown to enable coherent amplification of light quanta powered by the BH gravitational vacuum energy. This process can har…
-symmetric effects in measurement-based quantum thermal machines
Jonas F. G. Santos, Pritam Chattopadhyay
Measurement-based quantum thermal machines are fascinating models of thermodynamic cycles where measurement protocols play an important role in the performance and functioning of t…
Revisiting thermodynamics in computation and information theory
Pritam Chattopadhyay, Goutam Paul
One of the primary motivations of the research in the field of computation is to optimize the cost of computation. The major ingredient that a computer needs is the energy to run a…
Quantum Cycle in Relativistic Non-Commutative Space with Generalized Uncertainty Principle correction
Pritam Chattopadhyay, Tanmoy Pandit, Ayan Mitra +1
Quantum heat cycles and quantum refrigerators are analyzed using various quantum systems as their working mediums. For example, to evaluate the efficiency and the work done of the…
Binary Black Hole Information Loss Paradox & Future Prospects
Ayan Mitra, Pritam Chattopadhyay, Goutam Paul +1
Various techniques to tackle the black hole information paradox have been proposed. A new way out to tackle the paradox is via the use of a pseudo-density operator. This approach h…
Non-commutative space engine: a boost to thermodynamic processes
Tanmoy Pandit, Pritam Chattopadhyay, Goutam Paul
We introduce quantum heat engines that perform quantum Otto cycle and the quantum Stirling cycle by using a coupled pair of harmonic oscillator as its working substance. In the qua…
Non-Commutative space: boon or bane for quantum engines and refrigerators
Pritam Chattopadhyay
Various quantum systems are considered as the working substance for the analysis of quantum heat cycles and quantum refrigerators. The ongoing technological challenge is how effici…
Relativistic quantum heat engine from uncertainty relation standpoint
