Effectively supporting students in mastering all facets of self-regulated learning is a central aim of teachers and educational researchers. Prior research could demonstrate that f…
Local temperature control of magnon frequency and direction of supercurrents in a magnon Bose-Einstein condensate
Matthias R. Schweizer, Franziska Kühn, Victor S. L'vov +4
The creation of temperature variations in magnetization, and hence in the frequencies of the magnon spectrum in laser-heated regions of magnetic films, is an important method for s…
Multi-objective Quantum Annealing approach for solving flexible job shop scheduling in manufacturing
Philipp Schworm, Xiangquian Wu, Matthias Klar +2
Flexible Job Shop Scheduling (FJSSP) is a complex optimization problem crucial for real-world process scheduling in manufacturing. Efficiently solving such problems is vital for ma…
All-optical measurement of magnetic fields for quantum gas experiments
Suthep Pomjaksilp, Sven Schmidt, Aaron Thielmann +2
We present an all-optical method to measure and compensate for residual magnetic fields present in a cloud of ultracold atoms trapped in an optical dipole trap. Our approach levera…
Bose-Einstein condensation in systems with flux equilibrium
Victor S. L'vov, Anna Pomyalov, Sergey V. Nazarenko +4
We consider flux equilibrium in dissipative nonlinear wave systems subject to external energy pumping. In such systems, the elementary excitations, or quasiparticles, can create a…
Nonlinear erasing of propagating spin-wave pulses in thin-film Ga:YIG
David Breitbach, Moritz Bechberger, Björn Heinz +8
Nonlinear phenomena are key for magnon-based information processing, but the nonlinear interaction between two spin-wave signals requires their spatio-temporal overlap which can be…
Stabilizing an ultracold Fermi gas against Fermi acceleration to superdiffusion through localization
Sian Barbosa, Maximilian Kiefer-Emmanouilidis, Felix Lang +2
Anderson localization, i.e., destructive quantum interference of multiple-scattering paths, halts transport entirely. Contrarily, time-dependent random forces expedite transport vi…
What can we learn from diffusion about Anderson localization of a degenerate Fermi gas?
Sian Barbosa, Maximilian Kiefer-Emmanouilidis, Felix Lang +2
Disorder can fundamentally modify the transport properties of a system. A striking example is Anderson localization, suppressing transport due to destructive interference of propag…
Chiral quantum router with Rydberg atoms
Nikolaos E. Palaiodimopoulos, Simon Ohler, Michael Fleischhauer +1
We exploit controlled breaking of time-reversal symmetry to realize coherent routing of quantum information in spin networks. The key component of our scheme is a spin triangle who…
On symmetry adapted bases in trigonometric optimization
Tobias Metzlaff
The problem of computing the global minimum of a trigonometric polynomial is computationally hard. We address this problem for the case, where the polynomial is invariant under the…
