We present KITE, a general purpose open-source tight-binding software for accurate real-space simulations of electronic structure and quantum transport properties of large-scale molecular and condensed systems with tens of billions of atomic orbitals

We study the emergence of edge-magnetism in zigzag nanoribbons from electron-electron interactions in a minimal 3-band tight-binding descrip¬tion of transition-metal dichalcogenide monolayers with an intra-orbital Hub¬bard term. We explain the infl

In this paper, we developed a basis-independent perturbative method for calculating the non-linear optical response of arbitrary non-interacting tight-binding models. Our method is based on the non-equilibrium Keldysh formalism and allows an efficien

Van der Waals (vdW) heterostructures ---formed by stacking or growing two-dimensional (2D) crystals on top of each other--- have emerged as a new promising route to tailor and engineer the properties of 2D materials. Twisted bilayer graphene (tBLG),

Using a method based on the time-evolution of the occupied states at zero temperature, we observe the onset of a quasi-uniform and quasisteady state current across a disordered tight-binding chain, coupled between two finite (but large) clean leads w

Using KITE [1], a quantum transport software developed by ourselves, we explore the effect of disorder in the second-order con¬ductivity, aiming to reproduce mesoscopic samples under more realistic models of disorder. This work will be concerned abo

In this paper we investigate how the complexity of chaotic phase spaces affect the efficiency of importance sampling Monte Carlo simulations. We focus on a flat-histogram simulation of the distribution of finite-time Lyapunov exponent in a simple cha

Magnetic-tunnel junctions MTJs with ultra-thin (∼6–9 A) oxide barriers, having the resistance-area product as low as 1–10 Ω μm 2 , and magnetoresistance as high as ∼20%, were studied. In the temperature range from 300 to 25 K, they display
