English We study the quantum phase transition from an insulator to a metal realized at <i>t</i> =<i>t</i>′ <sub>c</sub> <0.5<i>t</i> in the ground state of the half-filled Hubbard chain with both nearest-neighbor (<i>t</i>) and next-nearest-neighbor (<i>t</i>') hopping. The study is carried out using the bosonization approach and density-matrix renormalization-group calculations. An effective... Show more…
