Hybrid phase at the quantum melting of the Wigner crystal
Houman Falakshahi, Xavier Waintal
We study the quantum melting of the two-dimensional Wigner crystal using a fixed node quantum Monte-Carlo approach. In addition to the two already known phases (Fermi liquid at lar…
Effect of a lattice upon an interacting system of electrons in two dimensions: Breakdown of scaling and decay of persistent currents
Houman Falakshahi, Zoltán Ádám Németh, Jean-Louis Pichard
The ground state of an electron gas is characterized by the interparticle spacing to the effective Bohr radius ratio r_s=a/a_B*. For polarized electrons on a two dimensional square…
Effect of a lattice upon an interacting system of electrons: Breakdown of scaling and decay of persistent currents
Houman Falakshahi, Zoltan Adam Nemeth, Jean-Louis Pichard
For an interacting system of N electrons, we study the conditions under which a lattice model of size L with nearest neighbor hopping t and U/r Coulomb repulsion has the same groun…
