Heat current in non-Markovian open systems

open access: yesNew Journal of Physics, 2023
We generalize time-evolving matrix product operators method to nonequilibrium quantum transport problems. The nonequilibrium current is obtained via numerical differentiation of the generating functional which is represented as a tensor network.

Variational Optimization of Continuous Matrix Product States [PDF]

open access: yesPhysical Review Letters, 2022
Just as matrix product states represent ground states of one-dimensional quantum spin systems faithfully, continuous matrix product states (cMPS) provide faithful representations of the vacuum of interacting field theories in one spatial dimension. Unlike the quantum spin case however, for which the density matrix renormalization group and related ...

Language as a matrix product state

open access: yesCoRR, 2017
We propose a statistical model for natural language that begins by considering language as a monoid, then representing it in complex matrices with a compatible translation invariant probability measure. We interpret the probability measure as arising via the Born rule from a translation invariant matrix product state.

Row Compression and Nested Product Decomposition of a Hierarchical Representation of a Quasiseparable Matrix [PDF]

open access: yes, 2014
This research introduces a row compression and nested product decomposition of an nxn hierarchical representation of a rank structured matrix A, which extends the compression and nested product decomposition of a quasiseparable matrix.

Entanglement classification with matrix product states [PDF]

open access: yesScientific Reports, 2016
AbstractWe propose an entanglement classification for symmetric quantum states based on their diagonal matrix-product-state (MPS) representation. The proposed classification, which preserves the stochastic local operation assisted with classical communication (SLOCC) criterion, relates entanglement families to the interaction length of Hamiltonians.

Thermal pure quantum matrix product states recovering a volume law entanglement

open access: yesPhysical Review Research, 2021
We propose a way to construct a thermal pure quantum matrix product state (TPQ-MPS) that can simulate finite-temperature quantum many-body systems with a minimal numerical cost comparable to the matrix product algorithm for the ground state.

Probabilistic Modeling with Matrix Product States [PDF]

open access: yesEntropy, 2019
Inspired by the possibility that generative models based on quantum circuits can provide a useful inductive bias for sequence modeling tasks, we propose an efficient training algorithm for a subset of classically simulable quantum circuit models.

Scalar one-point functions and matrix product states of AdS/dCFT

open access: yesPhysics Letters B, 2018
We determine in a closed form all scalar one-point functions of the defect CFT dual to the D3–D5 probe brane system with k units of flux which amounts to calculating the overlap between a Bethe eigenstate of the integrable SO(6) spin chain and a certain ...
