Calculating the polarization in bi-partite lattice models: application to an extended Su-Schrieffer-Heeger model

Balázs Hetényi, Yetkin Pulcu, Serkan Doğan

We address the question of different representation of Bloch states for lattices with a basis, with a focus on topological systems. The representations differ in the relative phase…

Interaction driven polarization shift in the $t - V - V^{'}$ lattice fermion model at half filling: emergent Haldane phase

Balázs Hetényi

We study the $t - V - V^{'}$ model in one dimension at half-filling. It is known that for large enough $V$ fixed, as $V^{'}$ is varied, the system goes from a charge-density wave into a Lutt…

Quantum phase transitions from analysis of the polarization amplitude

Balázs Hetényi, Balázs Dóra

In the modern theory of polarization, polarization itself is given by a geometric phase. In calculations for interacting systems the polarization and its variance are obtained from…
