Projector-based renormalization method (PRM) and its application to many-particle systems
A. Hübsch, S. Sykora, K. W. Becker
Despite the advances in the development of numerical methods analytical approaches play a key role on the way towards a deeper understanding of strongly interacting systems. In thi…

Analytical approach to the quantum-phase transition in the one-dimensional spinless Holstein model
S. Sykora, A. Huebsch, K. W. Becker
We study the one-dimensional Holstein model of spinless fermions interacting with dispersion-less phonons by using a recently developed projector-based renormalization method (PRM)…
