Spectral properties of the 2D Holstein t-J model [PDF]
, 1996 Employing the Lanczos algorithm in combination with a kernel polynomial moment expansion (KPM) and the maximum entropy method (MEM), we show a way of calculating charge and spin excitations in the Holstein t-J model, including the full quantum nature of ...

Holstein-Primakoff Realizations on Coadjoint Orbits [PDF]
, 1996 We derive the Holstein-Primakoff oscillator realization on the coadjoint orbits of the $SU(N+1)$ and $SU(1,N)$ group by treating the coadjoint orbits as a constrained system and performing the symplectic reduction.

Single Boson Images Via an Extended Holstein Primakoff Mapping [PDF]
, 1999 The Holstein-Primakoff mapping for pairs of bosons is extended in order to accommodate single boson mapping. The proposed extension allows a variety of applications and especially puts the formalism at finite temperature on firm grounds.
