Projected Entangled Pair States at Finite Temperature: Iterative Self-Consistent Bond Renormalization for Exact Imaginary Time Evolution
Piotr Czarnik, Jacek Dziarmaga
A projected entangled pair state (PEPS) with ancillas can be evolved in imaginary time to obtain thermal states of a strongly correlated quantum system on a 2D lattice. Every appli…

Striped critical spin liquid in a spin-orbital entangled RVB state in a projected entangled-pair state representation
Piotr Czarnik, Jacek Dziarmaga
We introduce a spin-orbital entangled (SOE) resonating valence bond (RVB) state on a square lattice of spins- and orbitals represented by pseudospins-. Like the s…
