Open AccessTopological phases of a dimerized Fermi–Hubbard model for semiconductor nano-lattices
Motivated by recent advances in fabricating artificial lattices in semiconductors and their promise for quantum simulation of topological materials, we study the one-dimensional dimerized Fermi–Hubbard model. ...

Giant multiphoton absorption for THz resonances in silicon hydrogenic donors
The absorption of multiple photons when there is no resonant intermediate state is a well-known nonlinear process in atomic vapours, dyes and semiconductors. The N-photon absorption (NPA) rate for donors in semic...
