Low-Energy Scattering Properties of Ground-State and Excited-State Positronium Collisions
Michael D. Higgins, Kevin M. Daily, Chris H. Greene
Low-energy elastic and inelastic scattering in the Ps(1)-Ps(2) channel is treated in a four-body hyperspherical coordinate calculation. Adiabatic potentials are calculated fo…
Hyperspherical Slater determinant approach to few-body fractional quantum Hall states
Bin Yan, Rachel E. Wooten, Kevin M. Daily +1
In a recent study[Phys. Rev. B 92 (2015) 125427], a hyperspherical approach has been developed to study of few-body fractional quantum Hall states. This method has been successfull…
Hyperspherical theory of the quantum Hall effect: the role of exceptional degeneracy
K. M. Daily, R. E. Wooten, Chris H. Greene
By separating the Schrödinger equation for noninteracting spin-polarized fermions in two-dimensional hyperspherical coordinates, we demonstrate that fractional quantum Hall (FQ…

Extension of the correlated Gaussian hyperspherical method to more particles and dimensions
Kevin M. Daily, Chris H. Greene
The solution of the hyperangular Schrödinger equation for few-body systems using a basis of explicitly correlated Gaussians remains numerically challenging. This is in part due to…
Three s-wave interacting fermions under anisotropic harmonic confinement: Dimensional crossover of energetics and virial coefficients
