Real-time bubble nucleation and growth for false vacuum decay on the lattice
Daan Maertens, Jutho Haegeman, Karel Van Acoleyen
We revisit quantum false vacuum decay for the one-dimensional Ising model, focusing on the real-time nucleation and growth of true vacuum bubbles. Via matrix product state simulati…
Matrix product state fixed points of non-Hermitian transfer matrices
Wei Tang, Frank Verstraete, Jutho Haegeman
The contraction of tensor networks is a central task in the application of tensor network methods to the study of quantum and classical many body systems. In this paper, we investi…
A critical lattice model for a Haagerup conformal field theory
Robijn Vanhove, Laurens Lootens, Maarten Van Damme +4
We use the formalism of strange correlators to construct a critical classical lattice model in two dimensions with the \emph{Haagerup fusion category} as input data…
A scaling hypothesis for matrix product states
Bram Vanhecke, Jutho Haegeman, Karel Van Acoleyen +2
We revisit the question of describing critical spin systems and field theories using matrix product states, and formulate a scaling hypothesis in terms of operators, eigenvalues of…
Renormalization group flows of Hamiltonians using tensor networks
Matthias Bal, Michaël Mariën, Jutho Haegeman +1
A renormalization group flow of Hamiltonians for two-dimensional classical partition functions is constructed using tensor networks. Similar to tensor network renormalization ([G.…
