Optimum Design of Corona Ring of Composite Insulators Considering the Effect of Mutual Phases by Monte Carlo and Coordinate Search Intelligente Algorithms [PDF]
مجله مدل سازی در مهندسیToday, composite insulators are used in high-voltage power transmission lines, especially in polluted and humid areas. One of the parameters affecting the aging of composite insulators is the control of the Electric Field Intensity (EFI) distribution on ...

Dual Dirac liquid on the surface of the electron topological insulator [PDF]
, 2015 We discuss a non-fermi liquid gapless metallic surface state of the topological band insulator. It has an odd number of gapless Dirac fermions coupled to a non-compact U(1) gauge field.

Microscopic Realization of 2-Dimensional Bosonic Topological Insulators [PDF]
, 2014 It is well known that a Bosonic Mott insulator can be realized by condensing vortices of a bo- son condensate. Usually, a vortex becomes an anti-vortex (and vice-versa) under time reversal symmetry, and the condensation of vortices results in a trivial ...

Entanglement in composite free-fermion systems [PDF]
, 2015 We consider fermionic chains where the two halves are either metals with different bandwidths or a metal and an insulator. Both are coupled together by a special bond.

Bosonic Analogue of Dirac Composite Fermi Liquid [PDF]
, 2016 We introduce a particle-hole-symmetric metallic state of bosons in a magnetic field at odd-integer filling. This state hosts composite fermions whose energy dispersion features a quadratic band touching and corresponding $2\pi$ Berry flux protected by ...

Composite fermi liquids in the lowest Landau level [PDF]
, 2016 We study composite fermi liquid (CFL) states in the lowest Landau level (LLL) limit at a generic filling $\nu = \frac{1}{n}$. We begin with the old observation that, in compressible states, the composite fermion in the lowest Landau level should be ...
