Infra-Bayesian Reinforcement Learning Agents Outperform Classical RL For Worst-Case Robustness

Manish Aryal, Faiyaz Azam, Agnivo Banerjee +12

Classical reinforcement learning assumes the agent interacts with a fixed environment whose behavior does not depend on the agent's policy. This assumption breaks down in non-reali…

Impact of the valence band on Rydberg excitons in cuprous oxide quantum wells

Niklas Scheuler, Jörg Main, Patric Rommel +3

The complex valence band structure of bulk cuprous oxide necessitates going beyond the parabolic approximation to precisely estimate exciton binding energies. The same is true for…

Wavefunctions and oscillator strengths of Rydberg excitons in cuprous oxide quantum wells

Leon Kühner, Patric Rommel, Jörg Main +2

We investigate the eigenstates, that is, the wavefunctions of Rydberg excitons in cuprous oxide quantum wells and derive expressions relating them to the oscillator strengths of di…

Quantum defects of Rydberg excitons in cuprous oxide: A semiclassical spherical model

Jan Ertl, Patric Rommel, Jörg Main

Excitons, i.e. the bound states of an electron and a positively charged hole are the solid state analogue of the hydrogen atom. As such they exhibit a Rydberg series, which in cupr…

Bound states in the continuum in cuprous oxide quantum wells

Angelos Aslanidis, Jörg Main, Patric Rommel +2

We propose a realistic semiconductor system containing bound states in the continuum (BICs) which allows for a practical realization. By varying the confinement strength of exciton…

Resonance energies and linewidths of Rydberg excitons in CuO quantum wells

Niklas Scheuler, Patric Rommel, Jörg Main +1

Rydberg excitons are the solid-state analog of Rydberg atoms and can, e.g., for cuprous oxide, easily reach a large size in the region of m for principal quantum numbers up to $…
