At this\r\nstage, it becomes increasingly important to also account for the effects of\r\nphysically inevitable environments. In particular, we study the transport\r\nproperties of the Hubbard-Holstein Hamiltonian that models a large class of\r\nmaterials characterized by strong electron-phonon coupling, in contact with a\r\ndissipative environment. Even in the one-dimensional and isolated case,\r\nsimulating the quantum dynamics of such a system with high accuracy is very\r\nchallenging due to the infinite dimensionality of the phononic Hilbert spaces.\r\nFor this reason, the effects of dissipation on the conductance properties of\r\nsuch systems have not been investigated systematically so far. We combine the\r\nnon-Markovian hierarchy of pure states method and the Markovian quantum jumps\r\nmethod with the newly introduced projected purified density-matrix\r\nrenormalization group, creating powerful tensor-network methods for dissipative\r\nquantum many-body systems. Investigating their numerical properties, we find a\r\nsignificant speedup up to a factor $\\sim 30$ compared to conventional\r\ntensor-network techniques. We apply these methods to study dissipative\r\nquenches, aiming for an in-depth understanding of the formation, stability, and\r\nquasi-particle properties of bipolarons. Surprisingly, our results show that in\r\nthe metallic phase dissipation localizes the bipolarons, which is reminiscent\r\nof an indirect quantum Zeno effect. However, the bipolaronic binding energy\r\nremains mainly unaffected, even in the presence of strong dissipation,\r\nexhibiting remarkable bipolaron stability. These findings shed light on the\r\nproblem of designing real materials exhibiting phonon-mediated\r\nhigh-$T_\\mathrm{C}$ superconductivity."}],"title":"Stable bipolarons in open quantum systems","date_updated":"2024-01-04T08:15:53Z","language":[{"iso":"eng"}]}
