Benchmarking quantum chaos from geometric complexity
Arpan Bhattacharyya, Suddhasattwa Brahma, Satyaki Chowdhury +1
Recent studies have shown that there is a strong interplay between quantum complexity and quantum chaos. In this work, we consider a new method to study geometric complexity for in…
The Early Universe as an Open Quantum System: Complexity and Decoherence
Arpan Bhattacharyya, Suddhasattwa Brahma, S. Shajidul Haque +2
In this work, we extend previous results, demonstrating how complexity in an open quantum system can identify decoherence between two fields, even in the presence of an acceleratin…
Kibble-Zurek mechanism and errors of gapped quantum phases
Amit Jamadagni, Javad Kazemi, Arpan Bhattacharyya
Kibble-Zurek mechanism relates the domain of non-equilibrium dynamics with the critical properties at equilibrium. It establishes a power law connection between non-equilibrium def…
