  • Diagonalizing Transfer Matr... Diagonalizing Transfer Matrices and Matrix Product Operators: A Medley of Exact and Computational Methods
    Haegeman, Jutho; Verstraete, Frank Annual review of condensed matter physics, 03/2017, Letnik: 8, Številka: 1
    Journal Article
    Recenzirano

    Transfer matrices and matrix product operators play a ubiquitous role in the field of many-body physics. This review gives an idiosyncratic overview of applications, exact results, and computational ...

  • Tangent-space methods for u... Tangent-space methods for uniform matrix product states
    Vanderstraeten, Laurens; Haegeman, Jutho; Verstraete, Frank SciPost physics lecture notes, 01/2019
    Journal Article
    Recenzirano
    Odprti dostop

    In these lecture notes we give a technical overview of tangent-space methods for matrix product states in the thermodynamic limit. We introduce the manifold of uniform matrix product states, show how ...

  • Post-matrix product state m... Post-matrix product state methods: To tangent space and beyond
    Haegeman, Jutho; Osborne, Tobias J.; Verstraete, Frank Physical review. B, Condensed matter and materials physics, 08/2013, Letnik: 88, Številka: 7
    Journal Article
    Recenzirano
    Odprti dostop

    We develop in full detail the formalism of tangent states to the manifold of matrix product states, and show how they naturally appear in studying time evolution, excitations, and spectral functions. ...

  • Gradient methods for variat... Gradient methods for variational optimization of projected entangled-pair states
    Vanderstraeten, Laurens; Haegeman, Jutho; Corboz, Philippe ... Physical review. B, 10/2016, Letnik: 94, Številka: 15
    Journal Article
    Recenzirano
    Odprti dostop

    We present a conjugate-gradient method for the ground-state optimization of projected entangled-pair states (PEPS) in the thermodynamic limit, as a direct implementation of the variational principle ...

  • Galois Conjugated Tensor Fu... Galois Conjugated Tensor Fusion Categories and Nonunitary Conformal Field Theory
    Lootens, Laurens; Vanhove, Robijn; Haegeman, Jutho ... Physical review letters, 03/2020, Letnik: 124, Številka: 12
    Journal Article
    Recenzirano
    Odprti dostop

    We provide a generalization of the matrix product operator formalism for string-net projected entangled pair states (PEPS) to include nonunitary solutions of the pentagon equation. These states ...

  • Matrix product states and v... Matrix product states and variational methods applied to critical quantum field theory
    Milsted, Ashley; Haegeman, Jutho; Osborne, Tobias J. Physical review. D, Particles, fields, gravitation, and cosmology, 10/2013, Letnik: 88, Številka: 8
    Journal Article
    Recenzirano
    Odprti dostop

    We study the second-order quantum phase transition of massive real scalar field theory with a quartic interaction in (1 + 1) dimensions on an infinite spatial lattice using matrix product states. We ...

  • Lattice regularisation and ... Lattice regularisation and entanglement structure of the Gross-Neveu model
    Roose, Gertian; Bultinck, Nick; Vanderstraeten, Laurens ... The journal of high energy physics, 07/2021, Letnik: 2021, Številka: 7
    Journal Article
    Recenzirano
    Odprti dostop

    A bstract We construct a Hamiltonian lattice regularisation of the N -flavour Gross-Neveu model that manifestly respects the full O(2 N ) symmetry, preventing the appearance of any unwanted marginal ...

  • Global Anomaly Detection in... Global Anomaly Detection in Two-Dimensional Symmetry-Protected Topological Phases
    Bultinck, Nick; Vanhove, Robijn; Haegeman, Jutho ... Physical review letters, 2018-Apr-13, Letnik: 120, Številka: 15
    Journal Article
    Recenzirano
    Odprti dostop

    Edge theories of symmetry-protected topological phases are well known to possess global symmetry anomalies. In this Letter we focus on two-dimensional bosonic phases protected by an on-site symmetry ...
