Phase diagram of the J1-J2 Heisenberg model on the kagome lattice
Fabian Kolley, Stefan Depenbrock, Ian P. McCulloch +2
We perform an extensive density matrix renormalization group (DMRG) study of the ground-state phase diagram of the spin-1/2 J_1-J_2 Heisenberg model on the kagome lattice. We focus…
Eigenstate thermalization hypothesis (ETH) and integrability in quantum spin chains
Vincenzo Alba
We investigate the eigenstate thermalization hypothesis (ETH) in integrable models, focusing on the spin-1/2 isotropic Heisenberg (XXX) chain. We provide numerical evidence that ET…
Bound states and entanglement in the excited states of quantum spin chains
Jan Mölter, Thomas Barthel, Ulrich Schollwöck +1
We investigate entanglement properties of the excited states of the spin-1/2 Heisenberg (XXX) chain with isotropic antiferromagnetic interactions, by exploiting the Bethe ansatz so…
Entanglement spreading after a geometric quench in quantum spin chains
Vincenzo Alba, Fabian Heidrich-Meisner
We investigate the entanglement spreading in the anisotropic spin-1/2 Heisenberg (XXZ) chain after a geometric quench. This corresponds to a sudden change of the geometry of the ch…
