Role of ion-pair states in the predissociation dynamics of Rydberg states of molecular iodine

Physical Chemistry Chemical Physics, 2016
The predissociation dynamics of superexcited iodine is studied by femtosecond ion imaging spectroscopy, providing direct control of wavepacket propagation in ion-pair states.

Interaction of molecular Rydberg states with metal surfaces

, 2005
The interaction between high-n Rydberg states of molecular hydrogen and metal surfaces has been investigated for the first time. Rydberg states of hydrogen possessing either 0 or 2 units of rotational angular momentum, defined by the quantum number N+ , and principal quantum numbers in the range n= 17 22 (for the N+= 2 states) and n=41-45 (for the N ...

Ultrafast many-body dynamics of dense Rydberg gases and ultracold plasma

Communications Physics
Understanding Coulomb driven many-body dynamics in ultracold atomic systems far from equilibrium remains an open challenge, particularly when ultrafast excitation channels create competing pathways toward Rydberg gases or ultracold plasmas.

Rydberg Molecules Bound by Strong Light Fields

PRX Quantum
The coupling of an isolated quantum state to a continuum is typically associated with decoherence and decreased lifetime. For coupling rates larger than the bandwidth of the associated continuum, decoherence can be mitigated, and new stable eigenstates ...

Quantum detection of microwave and terahertz signals using Rydberg EIT/EIA spectroscopy

Academia Quantum
Introduction: Quantum light–matter interaction provides an excellent application of Rydberg levels. Rydberg states are special in the sense that they have a long lifetime and large dipole moments.

Photon Molecules in Atomic Gases Trapped Near Photonic Crystal Waveguides

Physical Review X, 2016
Realizing systems that support robust, controlled interactions between individual photons is an exciting frontier of nonlinear optics. To this end, one approach that has emerged recently is to leverage atomic interactions to create strong and spatially ...

Franck–Condon factors and observed band strength distribution in the vibrational structure of the Ag2 D-X band system [PDF]

Journal of the Serbian Chemical Society, 2010
TPotential curves for the X1Sg+ and D1Su+ states of three diatomic silver isotopomers, 107Ag2, 107Ag109Ag and 109Ag2, were determined from the best available molecular constants by the Rydberg–Klein–Rees method.

Ionization energy of Rb_{2} by electric field ionization of molecular Rydberg states

Physical Review Research
We report the measurement of the ionization energy of the ^{85}Rb_{2} molecule through resonantly enhanced two-photon ionization in a supersonic beam. The first photon excites the X^{1}Σ_{g}^{+}(v_{X}=0)→B^{1}Π_{u}(v_{B}=2) transition, while the second ...

Antiprotonic helium atomcules

EPJ Web of Conferences, 2012
About 3% of antiprotons () stopped in helium are long-lived with microsecond lifetimes, against picoseconds in all other materials. This unusual longevity has been ascribed to the trapping of on metastable bound states in He+ helium atom-molecules thus ...
