    We study the complexity for an open quantum system. Our system is a harmonic oscillator coupled to a one-dimensional massless scalar field, which acts as the bath. Specifically, we consider the reduced density matrix by ...
  • Bhattacharyya, Arpan; Haque, S. Shajidul; Kim, Eugene H. (Cornell University Library, 2020-11)
    We investigate circuit complexity to characterize chaos in multiparticle quantum systems; concomitantly, we take strides in using complexity to characterize open quantum systems. By exploring different types of quantum ...
  • Lal, Nijil; Mishra, Sarika; Rani, Anju; Banerji, Anindya; Perumangattu, Chithrabhanu; Singh, R. P. (Cornell University Library, 2021-04)
    Duality in the entanglement of identical particles manifests that entanglement in only one variable can be revealed at a time. We demonstrate this using polarization and orbital angular momentum (OAM) variables of ...
  • Bhattacharyya, Arpan; Joshi, Lata Kh; Sundar, Bhuvanesh (Cornell University Library, 2021-11)
    In this review, we present the ongoing developments in bridging the gap between holography and experiments. To this end, we discuss information scrambling and models of quantum teleportation via Gao-Jafferis-Wall wormhole ...
  • Perumangatt, Chithrabhanu; Lal, Nijil; Anwar, Ali; Reddy, Salla Gangi; Singh, R. P. (Cornell University Library, 2016-07)
    We address the possibility of using even/odd states of orbital angular momentum (OAM) of photons for the quantum information tasks. Single photon qubit states and two photon entangled states in even/odd basis of OAM are ...
  • Saha, Madhumita; Venkatesh, B. Prasanna; Agarwalla, Bijay Kumar (Cornell University Library, 2022-02)
    Quasi-periodic lattice systems offer diverse transport properties. In this work, we investigate the environment induced effects on transport properties for quasi-periodic systems, namely the one-dimensional Aubry-André-Harper ...
