A Mechanical Implementation and Diagrammatic Calculation of Entangled Basis States
F. A. Buot, A. R. Elnar, G. Maglasang +1
We give for the first time a diagrammatic calculational tool of quantum entanglement. We present a pedagogical and simple mechanical implementation of quantum entanglement or "spoo…

On quantum Hall effect: Covariant derivatives, Wilson lines, gauge potentials, lattice Weyl transforms, and Chern numbers
Felix A. Buot
We show that the gauge symmetry of the nonequilibrium quantum transport of Chern insulator in a uniform electric field is governed by the Wilson line of parallel transport operator…

Comments on the Weyl-Wigner calculus for lattice models
Felix A. Buot
Here, we clarify the physical aspects between the discrete Weyl-Wigner (W-W) formalism, well developed in condensed matter physics, and the so-called 'precise Weyl-Wigner calculus…
