Spinless fermion model on diamond chain
Physics Letters A, 2011 The decoration or iteration transformation was widely applied to solve exactly the magnetic spin models in one-dimensional and two-dimensional lattice. The motif of this letter is to extend the decoration transformation approach for models that describe interacting electron systems instead of spin magnetic systems, one illustrative model to be studied,

The transverse field XY model on the diamond chain
Journal of Magnetism and Magnetic Materials, 2022 We consider the $s=1/2$ transverse field $XY$ model on the frustrated diamond chain, considering anisotropic exchange parameters between nearest-neighbor spins. To this end, we employ three different methodologies: mean-field approximations, and state-of-the-art exact diagonalizations (ED), and density matrix renormalization group (DMRG) simulations ...

3D characterisation of tool wear whilst diamond turning silicon [PDF]
, 2006 Nanometrically smooth infrared silicon optics can be manufactured by the diamond turning process. Due to its relatively low density, silicon is an ideal optical material for weight sensitive infrared (IR) applications. However, rapid diamond tool edge

Exact Ground States for Quasi 1D Systems with Hubbard Interaction [PDF]
Журнал нано- та електронної фізики, 2012 Using a positive semidefinite operator technique we deduced exact ground states for a modified diamond chain described by a non-integrable Hubbard model with on-site repulsion.

Interplay of disorder and interactions in a flat-band supporting diamond chain
Physical Review Research, 2020 We systematically study the effect of disorder and interactions on a quasi-one-dimensional diamond chain possessing flat bands. Disorder localizes all the single-particle eigenstates, while at low disorder strengths, we obtain weak flat-band based ...

Diamond chains with multiple-spin exchange interactions [PDF]
Physical Review B, 2009 We study the phase diagram of a symmetric spin-1/2 Heisenberg diamond chain with additional cyclic four-spin exchange interactions. The presented analysis supplemented by numerical exact-diagonalization results for finite periodic clusters implies a rich phase diagram containing, apart from standard magnetic and spin-liquid phases, two different ...
