A universal tensor network algorithm for any infinite lattice
Saeed S. Jahromi, Roman Orus
We present a general graph-based Projected Entangled-Pair State (gPEPS) algorithm to approximate ground states of nearest-neighbor local Hamiltonians on any lattice or graph of inf…

Dynamical structure factors of the spin-1/2 XXX chain at finite magnetic field
J. M. P. Carmelo, P. D. Sacramento, D. K. Campbell
We study the dynamical structure factors of the spin-1/2 XXX chain at finite magnetic field h, focusing in particular on the singularities at excitation energies in the vicinity of…
