“…While studies of state transport in lattices of Rydberg atoms have already been carried out [52,53], as far as we know the impact of singlet-triplet mixing in this context has not been previously considered. Denoting the 30 3 D 2 , 28 1 F 3 , 27 3 F 3 , and 28 3 F 3 states by |0 , |1 , |2 , and |3 , respectively, we numerically calculate the time evolution of the system at time t after the |1000 state is prepared.…”

We investigate the effect of intercombination transitions in excitation hopping processes such as those found in Förster resonance energy transfer. Taking strontium Rydberg states as our model system, the breakdown of LS coupling leads to weakly allowed transitions between Rydberg states of different spin quantum number. We show that the long-range interactions between two Rydberg atoms can be affected by these weakly allowed spin transitions, and the effect is greatest when there is a near degeneracy between the initial state and a state with a different spin quantum number. We also consider a case of four atoms in a spin chain and show that a spin impurity can resonantly hop along the chain. By engineering the many-body energy levels of the spin chain, the breakdown of LS coupling due to interelectronic effects in individual atoms can be mapped onto a spatial separation of the total spin and the total orbital angular momentum along the spin chain.

“…This analysis shows that a passing electron can 'switch on' a permanent dipole moment in the atom which is of the order of the transition dipole between neighboring Rydberg states and thus can reach several thousand Debye. This control on the singleatom level can be used, for example, to explore the interaction-induced transfer of a single excitation in a many-body system [33][34][35].…”

“…This method links to current experimental and theoretical efforts that aim to explore the coupling of quantum devices to solid state systems [17][18][19][20][21][22][23][24][25][26][27][28][29][30] and highlights the possibility to produce state changes of localized Rydberg atoms through electrons propagating in quantum wires or waveguides [31,32]. This approach can potentially find applications in the study and control of quantum many-body phenomena such as interaction-induced excitation transfer [33][34][35] and also in quantum information processing protocols that rely on the switching of interacting Rydberg states.…”

Abstract. We present and analyze a simple model to illustrate the possibility of Rydberg state control by means of a moving guided electron. Specifically, we consider alkali metal atoms whose valence electron is initially prepared in a Rydberg s-state and investigate state changes induced by the interaction with the nearby passing electron. We analyze the dependence of the atomic final state, obtained after the passage, on the electron's momentum. We identify experimentally accessible parameter regimes and discuss the experimental feasibility of the proposed scheme. We furthermore discuss the possibility to excite and manipulate many-body states of a chain of interacting Rydberg atoms.

“…One recently elaborated example is a possibility to use arrays of optical solitons, in dissipative two-dimensional [54] and conservative one-dimensional [55] setups alike, for building optical counterparts of the Newton's cradle (NC), which are well known in mechanics and molecular dynamics [56][57][58][59], and "supersolitons", i.e., self-supporting dislocations propagating in chains of individual solitons. Previously, "supersolitons" were experimentally realized and theoretically studied in chains of fluxons populating long periodically inhomogeneous Josephson junctions [60,61], and predicted in binary Bose-Einstein condensates (BECs), with attractive interactions in each component and repulsion between them [62].…”

We demonstrate the existence of stable collective excitation in the form of "supersolitons" propagating through chains of solitons with alternating signs (i.e., Newton's cradles built of solitons) in nonlinear optical couplers, including the PT -symmetric version thereof. In the regular coupler, stable supersolitons are created in the cradles composed of both symmetric solitons and asymmetric ones with alternating polarities. Collisions between moving supersolitons are investigated too, by the means of direct simulations in both the regular and PT -symmetric couplers.
