Linear response of one-dimensional liquid He to external perturbations
M. Motta, G. Bertaina, E. Vitali +2
We study the response of one-dimensional liquid He to weak perturbations relying on the dynamical structure factor, , recently obtained via ab-initio techniques [Phys.…

One-dimensional liquid He: dynamical properties beyond Luttinger liquid theory
G. Bertaina, M. Motta, M. Rossi +2
We compute the zero-temperature dynamical structure factor of one-dimensional liquid He by means of state-of-the-art Quantum Monte Carlo and analytic continuation techniques. B…
