Towards Nonperturbative Solution of Quantum Dynamics : A Hamiltonian Mean Field Approximation Scheme with Perturbation Theory for Arbitray Strength of Interaction
B. P. Mahapatra
We introduce a non perturbative general approximation scheme (NGAS) that can handle interactions of any strength in quantum theory. This approach starts with an input Hamiltonian t…
Perturbation Theory for Arbitrary Coupling Strength ?
B. P. Mahapatra, N. B. Pradhan
We present a \emph{new} formulation of perturbation theory for quantum systems, designated here as: `mean field perturbation theory'(MFPT), which is free from power-series-expansio…
Square-Well Approximation for the Anharmonic and the Double-Well Oscillators
B. P. Mahapatra, N. B. Pradhan
A novel general approximation scheme (NGAS) proposed earlier (ref.2-3) is applied to the problem of the quartic anharmonic (QAHO) and the double-well-oscillator (QDWO) in quantum t…
A new general approximation scheme(NGAS) in quantum theory:application to the anharmonic- and double well oscillators
B. P. Mahapatra, N. Santi, N. B. Pradhan
A new scheme of approximation in quantum theory is proposed which is potentially applicable to arbtrary interacting systems. The method consists in in approximating the original Ha…
Generalized Hartree Method: A Novel Non-perturbative Scheme for Interacting Quantum systems
B. P. Mahapatra, N. Santi, N. B. Pradhan
A self-consistent, non-perturbative scheme of approximation is proposed for arbitrary interacting quantum systems by generalization of the Hartree method.The scheme consists in app…
