3D continuum phonon model for group-IV 2D materials
A general three-dimensional continuum model of phonons in two-dimensional materials is developed. Our first-principles derivation includes full consideration of the lattice anisotropy and flexural modes perpendicular to the layers and can thus be applied to any two-dimensional material. In this paper, we use the model to not only compare the phonon spectra among the group-IV materials but also ...

متن کاملA NUMERICAL RENORMALIZATION GROUP APPROACH FOR AN ELECTRON-PHONON INTERACTION
A finite chain calculation in terms of Hubbard X-operators is explored by setting up a vibronic Harniltonian. The model conveniently transformed into a form so that in the case of strong coupling a numerical renormalization group approach is applicable. To test the technique, a one particle Green function is calculated for the model Harniltonian
متن کاملThe Continuum between 2D and 3D Gesture Interaction
Gesture recognition studies held by HCI researchers focuses either on the detection of the performed gesture or on the frameworks to define gestures to be recognised, computer vision algorithms may be used in the process of recognition. But any gesture performed is preceded by a cognitive process and an exploration of the environment, detection of the object to be manipulated and the propriocep...
