Scattering and Bound States of a Deformed Quantum Mechanics

Chee-Leong Ching, Rajesh Parwani

We construct the exact position representation of a deformed quantum mechanics which exhibits an intrinsic maximum momentum and use it to study problems such as a particle in a box…

The Constraints and Spectra of a Deformed Quantum Mechanics

Chee-Leong Ching, Rajesh R. Parwani, Kuldip Singh

We examine a deformed quantum mechanics in which the commutator between coordinates and momenta is a function of momenta. The Jacobi identity constraint on a two-parameter class of…

Information and Cosmological Physics

Rajesh R. Parwani

We review an information-theoretic approach to quantum cosmology, summarising the key results obtained to date, including a suggestion that an accelerating universe will eventually…

Splitting of degenerate states in one-dimensional quantum mechanics

Avik Dutt, Trisha Nath, Sayan Kar +1

A classic no-go theorem in one-dimensional quantum mechanics can be evaded when the potentials are unbounded below, thus allowing for novel parity-paired degenerate energy bound st…

Nonlinear Quantum Cosmology of de Sitter Space

Rajesh R. Parwani, Siti Nursaba Tarih

We perform a minisuperspace analysis of an information-theoretic nonlinear Wheeler-deWitt (WDW) equation for de Sitter universes. The nonlinear WDW equation, which is in the form o…

Information and Particle Physics

Wei Khim Ng, Rajesh R. Parwani

Information measures for relativistic quantum spinors are constructed to satisfy various postulated properties such as normalisation invariance and positivity. Those measures are t…
