The C state of potassium dimer revisited: an~extensive study by polarisation labelling spectroscopy method
W. Jastrzebski, J Szczepkowski, P. Kowalczyk
The polarisation labelling spectroscopy technique was applied to study the C X band system in potassium dimer. About 1100 new r…
On the 1 electronic state in strontium dimer
Jacek Szczepkowski, Wlodzimierz Jastrzebski, Anna Grochola +1
The laser technique of polarisation labelling of levels has been used to study the excited 1 state of Sr, in most part heavily perturbed by the nei…
Excited electronic states of Sr: ab initio predictions and experimental observation of the state
Jacek Szczepkowskia, Marcin Gronowski, Anna Grochola +3
Despite its apparently simple nature with four valence electrons, the strontium dimer constitutes a challenge for modern electronic structure theory. Here we focus on excited elect…
Study of excited electronic states of the KCs molecule correlated with the K(S)+Cs(D) asymptote: experiment and theory
Jacek Szczepkowski, Anna Grochola, Wlodzimierz Jastrzebski +4
Using the polarisation labelling spectroscopy, we performed the detailed analysis of the level structure of excited electronic states of the KCs molecule in the excitation e…
The C(2) state in Rb. Observation and deperturbation
Asen Pashov, Pawel Kowalczyk, Jacek Szczepkowski +1
We report a systematic study of the C(2) electronic state in rubidium dimer, observed in polarization labelling spectroscopy experiment through the C X$^{1}Σ^{+…
On the 3 state in caesium dimer
Jacek Szczepkowski, Anna Grochola, Wlodzimierz Jastrzebski +1
Polarisation labelling spectroscopy technique was employed to study the 3 state of Cs molecule. The main equlibrium constants are cm, $ω_e=30.61…
The RbSr ground state investigated via spectroscopy of hot & ultracold molecules
Alessio Ciamei, Jacek Szczepkowski, Alex Bayerle +9
We report on spectroscopic studies of hot and ultracold RbSr molecules, and combine the results in an analysis that allows us to fit a potential energy curve (PEC) for the X(1)$^2Σ…
Experimental and theoretical study of the B(2) X(1) system in the KSr molecule
Jacek Szczepkowski, Anna Grochola, Paweł Kowalczyk +4
Spectral bands for the B(2) X(1) electronic transition in the doubly-polar open-shell KSr molecule are recorded at moderate resolution using the th…
Quantum degenerate mixtures of strontium and rubidium atoms
Benjamin Pasquiou, Alex Bayerle, Slava Tzanova +5
We report on the realization of quantum degenerate gas mixtures of the alkaline-earth element strontium with the alkali element rubidium. A key ingredient of our scheme is sympathe…
Matter-Wave Interference versus Spontaneous Pattern Formation in Spinor Bose-Einstein Condensate
Marcin Witkowski, Rafal Gartman, Bartlomiej Nagorny +7
We describe effects of matter-wave interference of spinor states in the Rb Bose-Einstein condensate. The components of the F=2 manifold are populated by forced Majorana tran…
Analysis and calibration of absorptive images of Bose-Einstein condensate at non-zero temperatures
J. Szczepkowski, R. Gartman, M. Witkowski +3
We describe the method allowing quantitative interpretation of absorptive images of mixtures of BEC and thermal atoms which reduces possible systematic errors associated with evalu…
