WebSep 30, 2024 · The problem of impurities in mediums formed by bosons is comprehensively studied in condensed matter physics. Even properties of a single atom immersed in the weakly interacting Bose gas change drastically [1,2,3,4,5].Depending on the strength of the boson–impurity interaction, a number of physically distinct impurity phases can be … WebMore recent studies of the gap states include a numerical renormalization group analysis for a Kondo impurity [6], quantum Monte Carlo techniques applied to the symmetric Anderson model [7], large-N slave boson methods for an N-fold degenerate Anderson impurity [8] and a Bethe ansatz analysis for an Anderson impurity by Rupasov [9].

Effective many-body Hamiltonians of qubit-photon bound states
WebOct 18, 2024 · In the Markovian or weak coupling regime, the interaction of QEs through these single-photon bound states is known to lead to effective many-body QE Hamiltonians with tuneable but yet perturbative interactions. In this work we study the emergence of such models in the non-Markovian or strong coupling regime in different excitation subspaces.
