Generic Construction of Efficient Matrix Product Operators [PDF]

open access: yes, 2017
Matrix Product Operators (MPOs) are at the heart of the second-generation Density Matrix Renormalisation Group (DMRG) algorithm formulated in Matrix Product State language.

List Decoding of Matrix-Product Codes from nested codes: an application to Quasi-Cyclic codes [PDF]

open access: yes, 2012
A list decoding algorithm for matrix-product codes is provided when $C_1,..., C_s$ are nested linear codes and $A$ is a non-singular by columns matrix. We estimate the probability of getting more than one codeword as output when the constituent codes are

Exact bosonic Matrix Product States (and holography)

open access: yesJournal of High Energy Physics, 2019
We derive an exact formula for a matrix product state (MPS) representation (or a PEPS in higher number of dimensions) of the ground state of translationally invariant bosonic lattice systems in terms of a single one-dimensional Euclidean quantum ...

Zero Triple Product Determined Matrix Algebras

open access: yesJournal of Applied Mathematics, 2012
Let A be an algebra over a commutative unital ring C. We say that A is zero triple product determined if for every C-module X and every trilinear map {⋅,⋅,⋅}, the following holds: if {x,y,z}=0 whenever xyz=0, then there exists a C-linear operator T:A3⟶X ...

Continuum limits of Matrix Product States

open access: yes, 2018
We determine which translationally invariant matrix product states have a continuum limit, that is, which can be considered as discretized versions of states defined in the continuum.

The Reverse Order Law for the {1,3M,4N}—The Inverse of Two Matrix Products

open access: yesAxioms
By using the maximal and minimal ranks of some generalized Schur complement, the equivalent conditions for the reverse order law (AB){1,3M,4K}=B{1,3N,4K}A{1,3M,4N} are presented.

Out-of-equilibrium dynamics with matrix product states

open access: yesNew Journal of Physics, 2012
Theoretical understanding of strongly correlated systems in one spatial dimension has been greatly advanced by the density-matrix renormalization group (DMRG) algorithm, which is a variational approach using a class of entanglement-restricted states ...

Quantum Heat Statistics with Time-Evolving Matrix Product Operators

open access: yesPRX Quantum, 2021
We present a numerically exact method to compute the full counting statistics of heat transfer in non-Markovian open quantum systems, which is based on the time-evolving matrix product operator algorithm. This approach is applied to the paradigmatic spin-
