Krylov complexity for non-local spin chains
Aranya Bhattacharya, Pingal Pratyush Nath, Himanshu Sahu
Building upon recent research in spin systems with non-local interactions, this study investigates operator growth using the Krylov complexity in different non-local versions of th…
Complexity for one-dimensional discrete time quantum walk circuits
Aranya Bhattacharya, Himanshu Sahu, Ahmadullah Zahed +1
We compute the complexity for the mixed state density operator derived from a one-dimensional discrete-time quantum walk (DTQW). The complexity is computed using a two-qubit quantu…
Holographic complexity of Jackiw-Teitelboim gravity from Karch-Randall braneworld
Aranya Bhattacharya, Arpan Bhattacharyya, Ayan K. Patra
Recently, it has been argued in [1] that Jackiw-Teitelboim (JT) gravity can be naturally realized in the Karch-Randall braneworld in dimensions. Using the `complexity=volum…
On Krylov complexity in open systems: an approach via bi-Lanczos algorithm
Aranya Bhattacharya, Pratik Nandy, Pingal Pratyush Nath +1
Continuing the previous initiatives arXiv: 2207.05347 and arXiv: 2212.06180, we pursue the exploration of operator growth and Krylov complexity in dissipative open quantum systems.…
