Singularity with and without disorder at AKLT points
Loïc Herviou, Anthony Rey, Frédéric Mila
The Affleck-Kennedy-Lieb-Tasaki (AKLT) point of the bilinear-biquadratic spin-1 chain is a cornerstone example of a disorder point where short-range correlations become incommensur…

Weakly first-order melting of the 1/3 plateau in the Shastry-Sutherland model
Samuel Nyckees, Philippe Corboz, Frédéric Mila
We investigate the thermal properties of the 1/3 plateau in the Shastry-Sutherland model with infinite projected entangled-pair states (iPEPS) by performing the imaginary time evol…

Numerical investigation of the structure factors of the Read-Rezayi series
Loïc Herviou, Frédéric Mila
We numerically investigate the guiding center stucture factors of several states in the Read-Rezayi family. Using exact diagonalizations on the torus and density matrix renormaliza…
