A Generalized Nonlinear Extension of Quantum Mechanics

Alan Chodos, Fred Cooper

We construct the most general form of our previously proposed nonlinear extension of quantum mechanics that possesses three basic properties. Unlike the simpler model, the new vers…

Modeling pandemics

John F. Dawson, Fred Cooper, Efstathios G. Charalampidis

We review several models for pandemics that plagued the USA and the world in the past decade. Methods of data fitting are reviewed and several types of microscopic and rate equatio…

Solitary waves in the complementary generalized ABS model

Avinash Khare, Fred Cooper, John F. Dawson +1

We obtain exact solutions of the nonlinear Dirac equation in 1+1 dimension of the form $ Ψ(x,t) =Φ(x) \rme^{-\rmi ωt}$ where the nonlinear interactions are a combination of vect…

Connection Between the Exact Moving Solutions of the Negative Korteweg-de Vries (nKdV) Equation and the Negative Modified Korteweg-de Vries (nmKdV) Equation and the Static Solutions of 1+1 Dimensional Field Theory

Avinash Khare, Fred Cooper, Avadh Saxena

The negative order KdV (nKdV) and the modified KdV (nmKdV) equations have two different formulations based on different hierarchy operators. Both equations can be written in terms…

Solitary waves in a Two Parameter Family of Generalized Nonlinear Dirac Equations in Dimensions

Avinash Khare, Fred Cooper, John F. Dawson +1

We obtain exact solutions of the nonlinear Dirac equation in 1+1 dimension of the form where the nonlinear interactions are a combination of vector-vec…
