Zayedene: Carbon sp chains in diamond nanocavities [PDF]

, 2019
We propose a new class of carbon allotropes obtained by combining linear sp carbon chains with sp3 bulk carbon.The structure of these crystalline carbon allotropes consists of sp chains inserted in cylindrical cavities periodically arranged in hexagonal diamond (lonsdaleite).We carry out a detailed computational analysis of the structural, electronic ...

Exact solution of the mixed spin-1/2 and spin-S Ising-Heisenberg diamond chain

Condensed Matter Physics, 2009
The geometric frustration in a class of the mixed spin-1/2 and spin-S Ising-Heisenberg diamond chains is investigated by combining three exact analytical techniques: Kambe projection method, decoration-iteration transformation and transfer-matrix method.
