Tight-binding model for hydrogen-silicon interactions [PDF]
Physical Review B, 1992 We have developed an empirical tight-binding model for use in molecular-dynamics simulations to study hydrogen-silicon systems. The hydrogen-silicon interaction is constructed to reproduce the electronic energy levels and vibration frequencies of silane (${\mathrm{SiH}}_{4}$).

A minimal tight-binding model for the quasi-one-dimensional superconductor K2Cr3As3
New Journal of Physics, 2019 We present a systematic derivation of a minimal five-band tight-binding model for the description of the electronic structure of the recently discovered quasi-one-dimensional superconductor K _2 Cr _3 As _3 .

Landau levels in curved space realized in strained graphene
SciPost Physics Core, 2022 The quantum Hall effect in curved space has been the subject of many theoretical investigations in the past, but devising a physical system to observe this effect is hard.

Environment-dependent tight-binding potential model [PDF]
Physical Review B, 1996 We present a tight-binding model which goes beyond the traditional two-center approximation and allows the hopping parameters and the repulsive energy to be dependent on the binding environment. Using carbon as an example, we show that the approach improves remarkably the transferability of the tight-binding model.

The tight-binding formulation of the Kronig-Penney model [PDF]
Scientific Reports, 2017 AbstractElectronic band structure calculations are frequently parametrized in tight-binding form; the latter representation is then often used to study electron correlations. In this paper we provide a derivation of the tight-binding model that emerges from the exact solution of a particle bound in a periodic one-dimensional array of square well ...

Hidden correlation between absorption peaks in achiral carbon nanotubes and nanoribbons
Journal of Saudi Chemical Society, 2018 In this paper we study the effect of absorption peak correlation in finite length carbon nanotubes and graphene nanoribbons. It is shown, in the orthogonal π-orbital tight-binding model with the nearest neighbor approximation, that if the ribbon width is

Electrical analogue of one-dimensional and quasi-one-dimensional Aubry–André–Harper lattices
Scientific Reports, 2023 This work explores the potential for achieving correlated disorder in electrical circuits by utilizing reactive elements. By establishing a direct correspondence between the tight-binding Hamiltonian and the admittance matrix of the circuit, a novel ...
