One-dimensional Continuum Electronic Structure with the Density Matrix Renormalization Group and Its Implications For Density Functional Theory
E. M. Stoudenmire, Lucas O. Wagner, Steven R. White +1
We extend the density matrix renormalization group to compute exact ground states of continuum many-electron systems in one dimension with long-range interactions. We find the exac…
Studying Two Dimensional Systems With the Density Matrix Renormalization Group
E. M. Stoudenmire, Steven R. White
The Density Matrix Renormalization Group (DMRG) method scales exponentially in the system width for models in two dimensions, but remains one of the most powerful methods for study…
Interaction Effects in Topological Superconducting Wires Supporting Majorana Fermions
E. M. Stoudenmire, Jason Alicea, Oleg A. Starykh +1
Among the broad spectrum of systems predicted to exhibit topological superconductivity and Majorana fermions, one-dimensional wires with strong spin-orbit coupling provide one of t…
