Some results on retracts of polynomial rings
Sagnik Chakraborty, Nikhilesh Dasgupta, Amartya Kumar Dutta +1
In this paper, we first consider the relationship between a polynomial ring over a Noetherian domain and the ring of invariants of a -action on , when…
Information flow versus divisibility for qubit evolution
Sagnik Chakraborty, Dariusz Chruściński
We study the relation between lack of Information Backflow and completely positive divisibility (CP divisibility) for non-invertible qubit dynamical maps. Recently, these two conce…
Quantum precision thermometry with weak measurement
Arun Kumar Pati, Chiranjib Mukhopadhyay, Sagnik Chakraborty +1
As the minituarization of electronic devices, which are sensitive to temperature, grows apace, sensing of temperature with ever smaller probes is more important than ever. Genuinel…
