Dynamical Symmetry Approach to Periodic Hamiltonians
Hui Li, Dimitri Kusnezov
We show that dynamical symmetry methods can be applied to Hamiltonians with periodic potentials. We construct dynamical symmetry Hamiltonians for the Scarf potential and its extens…

Group Theoretical Properties and Band Structure of the Lame Hamiltonian
Hui Li, Dimitri Kusnezov, Francesco Iachello
We study the group theoretical properties of the Lame equation and its relation to su(1,1) and su(2). We compute the band structure, dispersion relation and transfer matrix and dis…

Group Theory Approach to Band Structure: Scarf and Lame Hamiltonians
Hui Li, Dimitri Kusnezov
The group theoretical treatment of bound and scattering state problems is extended to include band structure. We show that one can realize Hamiltonians with periodic potentials as…
