Trapping Abelian anyons in fractional quantum Hall droplets
Zi-Xiang Hu, Xin Wan, Peter Schmitteckert
We study the trapping of Abelian anyons (quasiholes and quasiparticles) by a local potential (e.g., induced by an AFM tip) in a microscopic model of fractional quantum Hall liquids…
Commensurability effects for fermionic atoms trapped in 1D optical lattices
Rafael A. Molina, Jorge Dukelsky, Peter Schmitteckert
Fermionic atoms in two different hyperfine states confined in optical lattices show strong commensurability effects due to the interplay between the atomic density wave (ADW) order…
Exact ground state density functional theory for impurity models coupled to external reservoirs and transport calculations
Peter Schmitteckert, Ferdinand Evers
A method is presented, which employs the density matrix renormalization group technique in order to construct exact ground state exchange correlation functionals for models of corr…
Numerical estimation of critical parameters using the Bond entropy
Rafael A. Molina, Peter Schmitteckert
Using a model of spinless fermions in a lattice with nearest neighbor and next-nearest neighbor interaction we show that the entropy of the reduced two site density matrix (the bon…
Strong enhancement of transport by interaction on contact links
Dan Bohr, Peter Schmitteckert
Strong repulsive interactions within a one dimensional Fermi system in a two-probe configuration normally lead to a reduced off-resonance conductance. We show that if the repulsive…
