High-accuracy Rb interaction potentials based on coupled cluster calculations
Jan Schnabel, Lan Cheng, Andreas Köhn
This work discusses a protocol for constructing highly accurate potential energy curves (PECs) for the lowest two states of Rb, i.e. and ,…
Limitations of coupled cluster approximations for highlyaccurate investigations of Rb
Jan Schnabel, Lan Cheng, Andreas Köhn
We reveal limitations of several standard coupled-cluster (CC) methods with perturbation-theorybased noniterative or approximate iterative treatments of triple excitations when app…
Towards photoassociation processes of ultracold rubidium trimers
Jan Schnabel, Tobias Kampschulte, Simon Rupp +2
We theoretically investigate the prospects for photoassociation (PA) of Rb, in particular at close range. We provide an overview of accessible states and possible transitions.…
-symmetric wave guide system with evidence of a third-order exceptional point
Jan Schnabel, Holger Cartarius, Jörg Main +2
An experimental setup of three coupled -symmetric wave guides showing the characteristics of a third-order exceptional point (EP3) has been investigated in an idealiz…
Realizing PT-symmetric BEC subsystems in closed hermitian systems
Robin Gutöhrlein, Jan Schnabel, Ibrokhim Iskandarov +3
In open double-well Bose-Einstein condensate systems which balance in- and outfluxes of atoms and which are effectively described by a non-hermitian PT-symmetric Hamiltonian PT-sym…
