Unification of Mixed Hilbert-Space Representations in Condensed Matter Physics and Quantum Field Theory
Felix A. Buot, Gibson T. Maglasang, Allan Roy B. Elnar
We present a unification of mixed-space quantum representations in Condensed Matter Physics (CMP) and Quantum Field Theory (QFT). The unifying formalism is based on being able to e…
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…
On quantum Hall effect, Kosterlitz-Thouless phase transition, Dirac magnetic monopole, and Bohr-Sommerfeld quantization
Felix A. Buot, Allan Roy Elnar, Gibson Maglasang +1
We addressed quantization phenomena in transport and vortex/precession-motion of low-dimensional systems, stationary quantization of confined motion in phase space due to oscillato…
Nonequilibrium superfield and lattice Weyl transform transport approach to quantum Hall effect
Felix A. Buot
We derive the topological Chern number of the integer quantum Hall effect in electrical conductivity, using Buot's superfield and lattice Weyl transform nonequilibrium quantum tran…
Generalized Nonequilibrium Quantum Transport of Spin and Pseudospins: Entanglements and Topological Phases
Felix A. Buot, Karla B. Rivero, Roland E. S. Otadoy
General nonequilibrium quantum transport equations are derived for a coupled system of charge carriers, Dirac spin, isospin (or valley spin), and pseudospin, such as either one of…
