Ground-state properties of the hydrogen chain: insulator-to-metal transition, dimerization, and magnetic phases
Mario Motta, Claudio Genovese, Fengjie Ma +14
Accurate and predictive computations of the quantum-mechanical behavior of many interacting electrons in realistic atomic environments are critical for the theoretical design of ma…
Spinon confinement and deconfinement in spin-1 chains
Laurens Vanderstraeten, Elisabeth Wybo, Natalia Chepiga +2
Motivated by the rich phase diagrams recently unveiled in frustrated spin-1 chains with competing next-nearest neighbour and four-spin interactions, we investigate the nature of th…
Dimerization and effective decoupling in two spin-1 generalizations of the spin-1/2 Majumdar-Ghosh chain
Natalia Chepiga, Frédéric Mila
We perform a systematic DMRG investigation of the two natural spin-1 generalizations of the spin-1/2 Majumdar-Ghosh chain, the spin-1 Heisenberg chain, where is a n…
Comb tensor networks
Natalia Chepiga, Steven R. White
In this paper we propose a special type of a tree tensor network that has the geometry of a comb---a 1D backbone with finite 1D teeth projecting out from it. This tensor network is…
