Contact Interactions on Graph Superlattices
We consider a quantum mechanical particle living on a graph and discuss the behaviour of its wavefunction at graph vertices. In addition to the standard (or type) boundary conditions with continuous wavefunctions, we investigate two types of a singular coupling which are analogous to the 0 interaction and its symmetrized version for particle on a line. We show that these couplings can be used t...
متن کاملdynamic coloring of graph
در این پایان نامه رنگ آمیزی دینامیکی یک گراف را بیان و مطالعه می کنیم. یک –kرنگ آمیزی سره ی رأسی گراف g را رنگ آمیزی دینامیکی می نامند اگر در همسایه های هر رأس v?v(g) با درجه ی حداقل 2، حداقل 2 رنگ متفاوت ظاهر شوند. کوچکترین عدد صحیح k، به طوری که g دارای –kرنگ آمیزی دینامیکی باشد را عدد رنگی دینامیکی g می نامند و آنرا با نماد ?_2 (g) نمایش می دهند. مونت گمری حدس زده است که تمام گراف های منتظم ...

in this paper we introduce mixed unitary cayley graph $m_{n}$ $(n>1)$ and compute its eigenvalues. we also compute the energy of $m_{n}$ for some $n$.
متن کاملDipole-allowed direct band gap silicon superlattices
Silicon is the most popular material used in electronic devices. However, its poor optical properties owing to its indirect band gap nature limit its usage in optoelectronic devices. Here we present the discovery of super-stable pure-silicon superlattice structures that can serve as promising materials for solar cell applications and can lead to the realization of pure Si-based optoelectronic d...
متن کاملTriple Band Rectangular Microstrip Antenna for S & C Band Applications
In this paper, triple band rectangular microstrip antenna with two vertical rhombus shaped slot (TBRMA2VRS) is designed and developed for S and C band frequency applications. The triple bands are obtained by etching two rhombus slots on the patch surface. The impedance bandwidth of secondary band is enhanced from 2.06% to8.54% by replacing the two rhombus slots. The radiation patterns measured ...
