Fractional Chern insulators on cylinders: Tao-Thouless states and beyond
Felix A. Palm, Chloé Van Bastelaere, Laurens Vanderstraeten
Topological phases in two-dimensional quantum lattice models are often studied on cylinders for revealing different topological properties and making the problem numerically tracta…
Fractional Quantum Hall Wedding Cakes
Chloé Van Bastelaere, Felix A. Palm, Botao Wang +2
This work investigates the coexistence of distinct topologically ordered phases within a single setup. We demonstrate this concept through tensor network simulations of the Hofstad…
Spectral Functions of an Extended Antiferromagnetic Heisenberg Model on the Triangular Lattice
Markus Drescher, Laurens Vanderstraeten, Roderich Moessner +1
We study an extended spin- antiferromagnetic Heisenberg model on the triangular lattice, which includes both nearest- and next-nearest-neighbor interactions, as well as a scal…
Gauging the variational optimization of projected entangled-pair states
Wei Tang, Laurens Vanderstraeten, Jutho Haegeman
Projected entangled-pair states (PEPS) constitute a powerful variational ansatz for capturing ground state physics of two-dimensional quantum systems. However, accurately computing…
Quantitative Description of Strongly Correlated Materials by Combining Downfolding Techniques and Tensor Networks
Daan Vrancken, Simon Ganne, Daan Verraes +5
We present a high-accuracy procedure for electronic structure calculations of strongly correlated materials. To address limitations in current electronic structure methods, we empl…
