Electrodynamics of tilted Dirac/Weyl materials: A unique platform for unusual surface plasmon polaritons

Zahra Jalali-Mola, S. A. Jafari

The electrodynamics of Weyl semimetals (WSMs) is an extension of Maxwell's theory where in addition to field strength tensor , an axion field enters the theory which is par…

Kinky plasmons in double layers of borophene-borophene and borophene-graphene

Zahra Jalali-Mola, S. A. Jafari

We investigate the collective plasmon modes in double layer of two dimensional materials where either one or both of the layers have tilted Dirac cone. Consistent with quite generi…

Tilt-induced kink in the plasmon dispersion of two-dimensional Dirac electrons

Z. Jalali-Mola, S. A. Jafari

The list of two dimensional Dirac systems with a tilt in their Dirac cone spectrum is expanding, and now in addition to organic system (BEDT-TTF)I includes the two dimen…

Electromagnetic modes from Stoner enhancement

Z. Jalali-Mola, S. A. Jafari

Systems with substantial spin fluctuations, can internally dress the polarization function by ladder diagram of Stoner (spin-flip) excitations. This process can drastically modify…

Exact phase diagram and topological phase transitions of the XYZ spin chain

S. A. Jafari

Within the block spin renormalization group we are able to construct the "exact" phase diagram of the XYZ spin chain. First we identify the Ising order along or a…

Exactly solvable spin chain models corresponding to BDI class of topological superconductors

S. A. Jafari, Farhad Shahbazi

We present an exactly solvable extension of the quantum XY chain with longer range multi-spin interactions. Topological phase transitions of the model are classified in terms of th…
