TensorNetwork on TensorFlow: Entanglement Renormalization for quantum critical lattice models

1 code implementation28 Jun 2019 Martin Ganahl, Ashley Milsted, Stefan Leichenauer, Jack Hidary, Guifre Vidal

We use the MERA to approximate the ground state wave function of the infinite, one-dimensional transverse field Ising model at criticality, and extract conformal data from the optimized ansatz.

Matrix product states and the nonabelian rotor model

1 code implementation23 Jul 2015 Ashley Milsted

We use uniform matrix product states (MPS) to study the (1+1)D $O(2)$ and $O(4)$ rotor models, which are equivalent to the Kogut-Susskind formulation of matter-free nonabelian lattice gauge theory on a "hawaiian earring" graph for $U(1)$ and $SU(2)$, respectively.

Variational Matrix Product Ansatz for Nonuniform Dynamics in the Thermodynamic Limit

1 code implementation3 Jul 2012 Ashley Milsted, Jutho Haegeman, Tobias J. Osborne, Frank Verstraete

We describe how to implement the time-dependent variational principle for matrix product states in the thermodynamic limit for nonuniform lattice systems.
