Abstract
We perform a matrix-product-state–based density matrix renormalisation group analysis of the phases for the disordered one-dimensional Bose-Hubbard model. For particle densities N/L = 1, 1/2 and 2 we show that it is possible to obtain a full phase diagram using only the entanglement properties, which come for free when performing an update. We confirm the presence of Mott insulating, superfluid and Bose glass phases when N/L = 1 and 1/2 (without the Mott insulator) as found in previous studies. For the N/L = 2 system we find a double-lobed superfluid phase with possible re-entrance.

Description: | The eespec folders are too large to be uploaded into the WRAP system and are therefore split into sections. To extract type the following into the linux terminal (e.g. for filling one): cat one_eespec.z01 one_eespec.z02 one_eespec.zip > one_eespec_full.zip zip -FF eespec_full.zip --out eespec_fixed.zip For the fixing stage (zip -FF) select skip when it asks for additional files. The zipping was performed in SUSE Linux Enterprise Desktop 11. The split folders should have sizes 4.7Gb, 5.2Gb and 13Gb for fillings one, half and two respectively. For further details on how to use this data see rest of usage guide. |
