Finite-size geometric crossover toward fragmentation of the potential energy shell in the quantum random energy model
Ishita Modak, Vatsana Tiwari, Soumya Bera
The quantum random energy model (QREM) is a paradigmatic model for studying delocalization-localization transitions at finite energy density in Fock space. In the computational bas…
Floquet mobility edges and transport in a periodically driven generalized Aubry-André model
Jayashis Das, Vatsana Tiwari, Manish Kumar +1
We investigate the effect of a periodic electric field drive on the generalized Aubry-André model, also known as the Ganeshan-Pixley-Das Sarma (GPD) model, which is well known as a…
Periodically and aperiodically Thue-Morse driven long-range systems: from dynamical localization to slow dynamics
Vatsana Tiwari, Devendra Singh Bhakuni, Auditya Sharma
We investigate the electric-field driven power-law random banded matrix(PLRBM) model where a variation in the power-law exponent yields a delocalization-to-localization phase t…
Photonic Simulation of Localization Phenomena Using Boson Sampling
Anuprita V. Kulkarni, Vatsana Tiwari, Auditya Sharma +1
Quantum simulation in its current state faces experimental overhead in terms of physical space and cooling. We propose boson sampling as an alternative compact synthetic platform p…
Quantum transport under oscillatory drive with disordered amplitude
Vatsana Tiwari, Sushanta Dattagupta, Devendra Singh Bhakuni +1
We investigate the dynamics of non-interacting particles in a one-dimensional tight-binding chain in the presence of an electric field with random amplitude drawn from a Gaussian d…
Dynamical localization and slow dynamics in quasiperiodically-driven quantum systems
Vatsana Tiwari, Devendra Singh Bhakuni, Auditya Sharma
We investigate the role of a quasiperiodically driven electric field in a one-dimensional disordered fermionic chain. In the clean non-interacting case, we show the emergence of dy…
Noise-induced dynamical localization and delocalization
Vatsana Tiwari, Devendra Singh Bhakuni, Auditya Sharma
We investigate the effect of a two-level jump process or random telegraph noise on a square wave driven tight-binding lattice. In the absence of the noise, the system is known to e…
