Low-lying spectra in anharmonic three-body oscillators with a strong short-range repulsion
نویسنده
چکیده
One-dimensional three-body Schrödinger equation is studied, with binding mediated by the power-law two-body long-range attraction V (x) = αx in superposition with a short-range repulsion V (x) = β/x (plus, possibly, further subdominant power-law components). Such an unsolvable and non-separable generalization of Calogero model (where one had L = K = 2) is shown to become separable and solvable at all integers K > 0 and L > 0 in the limit of the large repulsion β ≫ 1.

Convergent Rayleigh–Schrödinger perturbation expansions for low-lying eigenstates and eigenenergies of anharmonic oscillators in intermediate basis states
With suitably chosen unperturbed Hamiltonians, we show numerical evidence of convergence of Rayleigh–Schrödinger perturbation expansions for low-lying eigenstates and the corresponding eigenenergies of the quartic, sextic, and octic anharmonic oscillators, when the anharmonic terms are not very strong. In obtaining the perturbation expansions, unperturbed Hamiltonians are taken as the diagonal ...
متن کاملShort-range oscillators in power-series picture
Abstract The class of short-range potentials V [M (x) = ∑M m=2(fm + gm sinh x)/ cosh m x is considered as an asymptotically vanishing phenomenological alternative to the popular anharmonic long-range V (x) = ∑N n=2 hnx . We propose a method which parallels the analytic Hill-Taylor description of anharmonic oscillators and represents all the wave functions ψ (x) non-numerically, in terms of cert...
متن کاملAnharmonic Franck-Condon simulation of the absorption and fluorescence spectra for the low-lying S1 and S2 excited states of pyridine.
Anharmonic effects of the absorption and fluorescence spectra of pyridine molecule are studied and analyzed for the two-low lying singlet excited states S(1)((1)B(1)) and S(2)((1)B(2)). The complete active space self-consistent field (CASSCF) method is utilized to compute equilibrium geometries and all 27 vibrational normal-mode frequencies for the ground state and the two excited states. The p...
متن کاملLevel statistics for two-dimensional oscillators
We consider the level statistics of two-dimensional harmonic oscillators with incommensurable frequencies, which are known to have picket-fence type spectra. We propose a parametric representation for the level-spacing distribution and level-number variance, and study the variation of the parameters with the frequency ratio and the size of the spectra. By introducing an anharmonic perturbation,...

An implication of the spontaneous chiral symmetry breaking in QCD is that at low energy and resolution there appear quasiparticles-constituent quarks and Goldstone bosons. Thus, light and strange baryons should be considered as systems of three constituent quarks with confining interaction and a chiral interaction that is mediated by Goldstone bosons between the constituent quarks. We show how ...
