Second-order Raman and anharmonic lattice dynamics in lead-halide perovskites
Chao Shen, Florian Kluibenschedl, Ayan A. Zhumekenov +4
We explore the microscopic origin of THz-driven lattice dynamics in methylammonium lead bromide CHNHPbBr using two-dimensional THz Kerr-effect spectroscopy. The analysi…
Nonadiabatic laser-induced alignment dynamics of alkali dimers on the surface of a helium droplet
Henrik H. Kristensen, Lorenz Kranabetter, Areg Ghazaryan +6
Alkali dimers, , located on the surface of a helium nanodroplet, are set into rotation through the polarizability interaction with a nonresonant 1-ps-long laser puls…
Environment-limited transfer of angular momentum in Bose liquids
Alberto Cappellaro, Giacomo Bighin, Igor Cherepanov +1
Impurity motion in a many-body environment has been a central issue in the field of low-temperature physics for decades. In bosonic quantum fluids, the onset of a drag force experi…
Nonadiabatic Laser-Induced Alignment Dynamics of Molecules on a Surface
Lorenz Kranabetter, Henrik H. Kristensen, Areg Ghazaryan +7
We demonstrate that a sodium dimer, Na(), residing on the surface of a helium nanodroplet, can be set into rotation by a nonresonant 1.0 ps infrared laser pulse.…
Modeling laser pulses as -kicks: reevaluating the impulsive limit in molecular rotational dynamics
Volker Karle, Mikhail Lemeshko
The impulsive limit (the "sudden approximation") has been widely employed to describe the interaction between molecules and short, far-off-resonant laser pulses. This approximation…
Linear rotor in an ideal Bose gas near the threshold for binding
Tibor Dome, Artem G. Volosniev, Areg Ghazaryan +3
We study a linear rotor in a bosonic bath within the angulon formalism. Our focus is on systems where isotropic or anisotropic impurity-boson interactions support a shallow bound s…
