Frontiers in Physics, 2021 We analytically study quantum dissipative dynamics described by the Caldirola-Kanai model with inter-particle interactions. We have found that the dissipative quantum dynamics of the Caldirola-Kanai model can be exactly mapped to a dissipationless ...

Molecules, 2021 Resonance-assisted hydrogen bonds (RAHB) are intramolecular contacts that are characterised by being particularly energetic. This fact is often attributed to the delocalisation of π electrons in the system.

Coherent quantum depletion of an interacting atom condensate [PDF]
Nature Communications, 2015 AbstractSufficiently strong interactions promote coherent quantum transitions in spite of thermalization and losses, which are the adversaries of delicate effects such as reversibility and correlations. In atomic Bose–Einstein condensates (BECs), strong atom–atom interactions can eject atoms from the BEC to the normal component, yielding quantum ...

Controlling Interactions between Quantum Emitters Using Atom Arrays [PDF]
Physical Review Letters, 2021 We investigate two-dimensional atomic arrays as a platform to modify the electromagnetic environment of individual quantum emitters. Specifically, we demonstrate that control over emission linewidths, resonant frequency shifts, and local enhancement of driving fields is possible due to strong dipole-dipole interactions within ordered, subwavelength ...

Quantum spin transistor with a Heisenberg spin chain
Nature Communications, 2016 Systems of interacting quantum spins provide a basis for quantum computation devices. Here, the authors demonstrate a quantum spin transistor in a Heisenberg spin chain, which may be realized in a system of trapped cold atoms.

Experiments in Cavity QED: Exploring the Interaction of Quantized Light with a Single Trapped Atom [PDF]
, 2005 The experiments discussed in this thesis focus on the interaction of a single trapped atom with the single mode of a high-finesse optical cavity, in the regime of strong coupling.

Hydrogen transfer reaction: Bond formation and bond cleavage through the eyes of interacting quantum atoms [PDF]
Journal of the Serbian Chemical Society, 2019 Hydrogen transfer from hydroquinone to the methoxy radical was studied using the density functional theory. The energy decomposition technique, interacting quantum atoms, was employed for a detailed investigation of the changes that the bonds of interest

Experimental Study of the Role of Atomic Interactions on Quantum Transport [PDF]
Physical Review Letters, 2006 We report an experimental study of quantum transport for atoms confined in a periodic potential and compare between thermal and BEC initial conditions. We observe ballistic transport for all values of well depth and initial conditions, and the measured expansion velocity for thermal atoms is in excellent agreement with a single-particle model. For weak
