Decoding conformal field theories: from supervised to unsupervised learning
En-Jui Kuo, Alireza Seif, Rex Lundgren +2
We use machine learning to classify rational two-dimensional conformal field theories. We first use the energy spectra of these minimal models to train a supervised learning algori…
Momentum-space entanglement after a quench in one-dimensional disordered fermionic systems
Rex Lundgren, Fangli Liu, Pontus Laurell +1
We numerically investigate the momentum-space entanglement entropy and entanglement spectrum of the random-dimer model and its generalizations, which circumvent Anderson localizati…
Nematic order on the surface of a three-dimensional topological insulator
Rex Lundgren, Hennadii Yerzhakov, Joseph Maciejko
We study the spontaneous breaking of rotational symmetry in the helical surface state of three-dimensional topological insulators due to strong electron-electron interactions, focu…
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…
Universal entanglement spectra in critical spin chains
Rex Lundgren, Jonathan Blair, Pontus Laurell +4
We advocate that in critical spin chains, and possibly in a larger class of 1D critical models, a gap in the momentum-space entanglement spectrum separates the universal part of th…
Bulk Entanglement Spectrum in Gapped Spin Ladders
Raul A. Santos, Chao-Ming Jian, Rex Lundgren
We study the bulk entanglement of a series of gapped ground states of spin ladders, representative of the Haldane phase. These ground states of spin ladders generalize the va…
