The use of Entanglement Entropy to Classify Quantum Phase Transitions in 1D Ultracold Spinor Bosons.
(2018-07-24)
In this paper, we discuss a novel method based on a quantum-information-tool suitable
to identify and characterize quantum-phases and phase transitions in a broad set of lattice models relevant in condensed-matter systems. ...
Study of the bilinear biquadratic Heisenberg model on a honeycomb lattice via Schwinger bosons
(Journal of Magnetism and Magnetic Materials, 2018)
Duality and bosonization in Schwinger–Keldysh formulation
(IOP Publishing, 2014-10)
We present a path-integral bosonization approach for systems out of equilibrium based on a duality transformation of the original Dirac fermion theory combined with the Schwinger–Keldysh time closed contour technique, to ...
