Non-perturbative predictions for cold atom Bose gases with tunable interactions
Fred Cooper, Chih-Chun Chien, Bogdan Mihaila +2
We derive a theoretical description for dilute Bose gases as a loop expansion in terms of composite-field propagators by rewriting the Lagrangian in terms of auxiliary fields relat…
Stability and dynamical properties of Cooper-Shepard-Sodano compactons
Bogdan Mihaila, Andres Cardenas, Fred Cooper +1
Extending a Pade approximant method used for studying compactons in the Rosenau-Hyman (RH) equation, we study the numerical stability of single compactons of the Cooper-Shepard-Sod…
Solitary wave in the Nonlinear Dirac Equation with arbitrary nonlinearity
Fred Cooper, Avinash Khare, Bogdan Mihaila +1
We consider the nonlinear Dirac equations (NLDE's) in 1+1 dimension with scalar-scalar self interaction , as well as a vector-vector self intera…
Stability and dynamical properties of Rosenau-Hyman compactons using Pade approximants
Bogdan Mihaila, Andres Cardenas, Fred Cooper +1
We present a systematic approach for calculating higher-order derivatives of smooth functions on a uniform grid using Padé approximants. We illustrate our findings by deriving high…
Dynamics of particle production by strong electric fields in non-Abelian plasmas
John F. Dawson, Bogdan Mihaila, Fred Cooper
We develop methods for computing the dynamics of fermion pair production by strong color electric fields using the semi-classical Boltzmann-Vlasov equation. We present numerical re…
