Phase transitions in coupled Ising chains and SO()-symmetric spin chains
Yohei Fuji, Sylvain Capponi, Lukas Devos +1
The paper studies quantum phase transitions in a one‑dimensional system made of multiple coupled Ising chains, showing that for two or three chains the transition is continuous (Is…
PEPSKit.jl: A Julia package for projected entangled-pair state simulations
Paul Brehmer, Lander Burgelman, Zheng-Yuan Yue +3
We present PEPSKitjl, a Julia package for simulating two-dimensional quantum many-body systems with infinite projected entangled-pair states (iPEPS). PEPSKitjl builds on the…
Gapped spinful phases obtained via Gutzwiller projections of Euler states
Thorsten B. Wahl, Lukas Devos, Robert-Jan Slager
Gutzwiller projections of non-interacting chiral topological phases are known to give rise to fractional, topologically ordered chiral phases. Here, we carry out a similar construc…
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…
Finite-size scaling on the torus with periodic projected entangled-pair states
Gleb Fedorovich, Lukas Devos, Jutho Haegeman +3
An efficient algorithm is constructed for contracting two-dimensional tensor networks under periodic boundary conditions. The central ingredient is a novel renormalization step tha…
Non-Landau quantum phase transition in modulated SU(N) Heisenberg spin chains
Sylvain Capponi, Lukas Devos, Philippe Lecheminant +2
We investigate the nature of the quantum phase transition in modulated SU(N) Heisenberg spin chains. In the odd-N case, the transition separates a trivial non-degenerate phase to a…
