Momentum-space entanglement and Loschmidt echo in Luttinger liquids after a quantum quench
Balázs Dóra, Rex Lundgren, Mark Selover +1
Luttinger liquids (LLs) arise by coupling left- and right-moving particles through interactions in one dimension. This most natural partitioning of LLs is investigated by the momen…

Entanglement Entropy and Spectra of the One-dimensional Kugel-Khomskii Model
Rex Lundgren, Victor Chua, Gregory A. Fiete
We study the quantum entanglement of the spin and orbital degrees of freedom in the one- dimensional Kugel-Khomskii model, which includes both gapless and gapped phases, using anal…
