Probing information theoretic measures of nonlinear ultracold quantum gases using phase-space distributions

Mariyah Ughradar, Ramkumar Radhakrishnan, Siddharth Kumar Tiwari +1

We use phase space distributions, specifically the Wigner and Husimi quasi probability distributions, to study harmonically trapped Bose--Einstein condensate described by the Gross…

Phase space distributions in information theory

Vikash Kumar Ojha, Ramkumar Radhakrishnan, Siddharth Kumar Tiwari +1

We use phase space distributions specifically, the Wigner distribution (WD) and Husimi distribution (HD) to investigate certain information-theoretic measures as descriptors for a…

Quantum Information Measures in Quartic and Symmetric Potentials using perturbative approach

Vikash Kumar Ojha, Ramkumar Radhakrishnan, Mariyah Ughradar

We analyze the Shannon and Fisher information measures for systems subjected to quartic and symmetric potential wells. The wave functions are obtained by solving the time-independe…

Wigner distribution of Sine Gordon and Kink solitons

Ramkumar Radhakrishnan, Vikash Kumar Ojha

Wigner distributions play a significant role in formulating the phase space analogue of quantum mechanics. The Schrodinger wave-functional for solitons is needed to derive it for s…

New shape resonances in one dimension

Zafar Ahmed, Shashin Pavaskar, Lakshmi Prakash

Hitherto, a finitely thick barrier next to a well or a rigid wall has been considered the potential of simplest shape giving rise to resonances (metastable states) in one dimension…
