Quantum subdiffusion with two- and three-body interactions

We study the dynamics of a few-quantum-particle cloud in the presence of two- and three-body interactions in weakly disordered one-dimensional lattices. The interaction is dramatically enhancing the Anderson localization length \(\xi_1\) of noninteracting particles. We launch compact wave packets an...

Description
Summary:We study the dynamics of a few-quantum-particle cloud in the presence of two- and three-body interactions in weakly disordered one-dimensional lattices. The interaction is dramatically enhancing the Anderson localization length \(\xi_1\) of noninteracting particles. We launch compact wave packets and show that few-body interactions lead to transient subdiffusion of wave packets, \(m_2 \sim t^{\alpha}\), \(\alpha
