Broadcasting of NPT Entanglement in Two Qutrit Systems
Rounak Mundra, Sabuj Chattopadhyay, Indranil Chakrabarty +1
It is known that beyond and dimensional quantum systems, Peres-Hordecki criterion is no longer sufficient as an entanglement detection criterion as ther…
Broadcasting of non-locality
Dhrumil Patel, Arup Roy, Indranil Chakrabarty +1
Bell nonlocality and steering are archetypal characteristics of quantum mechanics that mark a significant departure from conventional classical notions. They basically refer to the…
Parameter space stability of multiple soft interactions
Rahul Kumar Thakur, Bhupendra Nath Tiwari, Rahul Nigam
We study the fluctuation theory analysis of multiple soft interactions that are used to design SIBYLL 2.1 and related cosmic ray event generators. We examine fluctuation stabilitie…
