Detecting emergent continuous symmetries at quantum criticality
Mingru Yang, Bram Vanhecke, Norbert Schuch
New or enlarged symmetries can emerge at the low-energy spectrum of a Hamiltonian that does not possess the symmetries, if the symmetry breaking terms in the Hamiltonian are irrele…
Learning Generative Models for Active Inference using Tensor Networks
Samuel T. Wauthier, Bram Vanhecke, Tim Verbelen +1
Active inference provides a general framework for behavior and learning in autonomous agents. It states that an agent will attempt to minimize its variational free energy, defined…
Partial lifting of degeneracy in the Ising antiferromagnet on the kagome lattice
Jeanne Colbois, Bram Vanhecke, Laurens Vanderstraeten +3
Motivated by dipolar-coupled artificial spin systems, we present a theoretical study of the classical Ising antiferromagnet on the kagome lattice. We establish the gr…
Contrasting pseudo-criticality in the classical two-dimensional Heisenberg and models: zero-temperature phase transition versus finite-temperature crossover
Lander Burgelman, Lukas Devos, Bram Vanhecke +2
Tensor-network methods are used to perform a comparative study of the two-dimensional classical Heisenberg and models. We demonstrate that uniform matrix product st…
