Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue on Quantum Dynamics in Hybrid Systems. This Special Issue is dedicated to theoretical/computational contributions addressing the quantum dynamics of hybrid systems, particularly those involving interactions between distinct domains, such as:

  1. Quantum–Classical Systems: Models for understanding the interplay between quantum and classical subsystems, focusing on decoherence, the quantum-to-classical transition, and the emergence of classical behavior from quantum systems.
  2. Electronic–Vibrational Interactions: Studies of coupled electronic and vibrational degrees of freedom, particularly in vibronic coupling, nonadiabatic dynamics, and charge and energy transport.
  3. Light–Matter Interactions: Exploration of strong coupling between light fields and matter, including spectroscopy, quantum optics, cavity physics and chemistry, ultra-cold quantum gases, and other photonic systems.
  4. Other Hybrid Systems: Investigating useful models for hybrid systems such as the spin-boson model and other quantum interactions that bridge different physical domains and multi-species systems.
  5. Multiconfigurational methodologies: Multiconfiguration time-dependent Hartree (MCTDH) and multilayer MCTDH and their variants for indistinguishable particles, coupled cluster (CC) methods, etc.

We welcome submissions of original theoretical and computational research articles, mathematical models, and review papers exploring hybrid systems' quantum dynamics, providing new insights and models that can guide experimental progress in these and other related areas.

We explore the ground-state properties of a single impurity immersed in a one-dimensional quantum droplet medium formed by a two-component Bose mixture. Relying on ab initio simulations, we demonstrate that tuning the impurity–droplet interactions allows to controllably reshape the droplets’ density profiles and associated correlation patterns. For attractive impurity-medium couplings, the impurity becomes localized within the droplet, which exhibits a density hump at the vicinity of the impurity, while repulsive interactions facilitate phase separation. Comparing our many-body results with the appropriate extended Gross–Pitaevskii description, we find adequate agreement for the droplet density profiles, with the effective field approach systematically overestimating impurity localization. Following a release of the external trap, we unveil that the sign and magnitude of the interactions between the impurity and the droplet hosts dictate the response of the three-component setting, which experiences expansion unless strongly attractive intercomponent couplings are present. These results corroborate the role and presence of correlations in impurity–droplet mixtures and inspire future investigations on impurity physics for probing droplet configurations. Full article

We investigate the optical response properties of an atom-assisted spinning optomechanical system, in which a spinning optical resonator is coupled simultaneously to a two-level atomic ensemble and a mechanical resonator driven by a weak pump field. Remarkably, we demonstrate that by simply reversing the rotation direction, the system can be switched between a low-absorption electromagnetic and optomechanically induced transparency state and a high-absorption state, constituting a form of non-reciprocal optical control at the quantum level. Furthermore, by tuning the phase difference between the mechanical pump and the probe field, direction-dependent switching between absorption and gain is achieved. These non-reciprocal effects originate from the Sagnac-induced frequency shift in the optical mode, which leads to distinct optomechanical and atom–cavity couplings for opposite spinning directions. We also show that the absorption spectrum can be modulated by the angular velocity and the atomic number. Our results indicate that the optical properties of the hybrid system can be manipulated via the angular velocity, phase difference, and atom number, with potential applications in chiral photonic communications.
