Simple models of three coupled -symmetric wave guides allowing for third-order exceptional points
Jan Schnabel, Holger Cartarius, Jörg Main +2
We study theoretical models of three coupled wave guides with a -symmetric distribution of gain and loss. A realistic matrix model is developed in terms of a three-mo…
-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…
Application of quantum annealing for scalable robotic assembly line optimization: a case study
Moritz Willmann, Marcel Albus, Jan Schnabel +1
The even distribution and optimization of tasks across resources and workstations is a critical process in manufacturing aimed at maximizing efficiency, productivity, and profitabi…
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 $(1) {}^2Σ{_u^+}…
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…
Quantum Kernel Methods under Scrutiny: A Benchmarking Study
Jan Schnabel, Marco Roth
Since the entry of kernel theory in the field of quantum machine learning, quantum kernel methods (QKMs) have gained increasing attention with regard to both probing promising appl…
