Matrix product state of multi-time correlations [PDF]
, 2020 For an interacting spatio-temporal lattice system we introduce a formal way of expressing multi-time correlation functions of local observables located at the same spatial point with a time state, i.e.

Heat current in non-Markovian open systems
New 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.

Continuous matrix product state tomography of quantum transport experiments
New Journal of Physics, 2015 In recent years, a close connection between the description of open quantum systems, the input–output formalism of quantum optics, and continuous matrix product states (cMPS) in quantum field theory has been established.

Thermal pure quantum matrix product states recovering a volume law entanglement
Physical 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.

Matrix product state representations [PDF]
, 2007 This work gives a detailed investigation of matrix product state (TOPS) representations for pure multipartite quantum states. We determine the freedom in representations with and without translation symmetry, derive respective canonical forms and provide

Integrable boundary states from maximal giant gravitons in ABJM theory
Physics Letters B, 2023 We investigate the integrability of the boundary state arising from the subdeterminant operators in the alternating SU(4) spin chain in ABJM theory. Our findings show that the resulting matrix product states are only integrable for two special giant ...

Continuous matrix product states for quantum fields [PDF]
, 2010 We define matrix product states in the continuum limit, without any reference to an underlying lattice parameter. This allows us to extend the density matrix renormalization group and variational matrix product state formalism to quantum field theories ...

Direct solution of multiple excitations in a matrix product state with block Lanczos [PDF]
, 2023 Matrix product state methods are known to be efficient for computing ground states of local, gapped Hamiltonians, particularly in one dimension. We introduce the multi-targeted density matrix renormalization group method that acts on a bundled matrix ...

Skeleton of matrix-product-state-solvable models connecting topological phases of matter
Physical Review Research, 2021 Models whose ground states can be written as an exact matrix-product state (MPS) provide valuable insights into phases of matter. While MPS-solvable models are typically studied as isolated points in a phase diagram, they can belong to a connected ...
