Lattice Hamiltonian approach to the Schwinger model: further results from the strong coupling expansion
Marcin Szyniszewski, Krzysztof Cichy, Agnieszka Kujawa-Cichy
We employ exact diagonalization with strong coupling expansion to the massless and massive Schwinger model. New results are presented for the ground state energy and scalar mass ga…

The generalized t-V model in one dimension
Marcin Szyniszewski, Evgeni Burovski
We develop a systematic strong coupling approach for studying an extended t-V model with interactions of a finite range. Our technique is not based on the Bethe ansatz and is appli…
