The novel meso-nucleo-spinics effect of the nuclear spin polarization induced periodic structure creation in a low-dimensional electron system is studied theoretically. It is shown that the periodically distributed nuclear magnetization results in the periodic hyperfine magnetic field which, in turn, creates a periodic electron structure. The electron wave functions and energy spectrum for such...

By developing the terahertz (THz) technology, in addition to generators and detectors of THz waves, the existence of some tools such as modulators and filters are needed. THz filters are important tools for various applications in the field of chemical and biological sensors. Linear and nonlinear optical properties of the graphene have attracted lots of attention. In fact graphene exhibits vari...
