• Abstract: Non-Hermitian, one-dimensional potentials which are also non-local, allow for scattering asymmetries, namely, asymmetric transmission or reflection responses to the incidence of a particle from left or right. The symmetries of the potential imply selection rules for transmission and reflection. In particular, parity-time (PT) symmetry or the symmetry of any local potential do not allow for asymmetric transmission. We put forward a feasible quantum-optical implementation of non-Hermitian, non-local, non-PT potentials to implement different scattering asymmetries, including transmission asymmetries.

  We show efficient symmetric and asymmetric Bell-state transfers, by modulating system parameters within a Jaynes-Cummings model. We further achieve perfect asymmetric Bell-state transfers even in the absence of an exceptional point (EP) Our work presents an approach to effectively and reliably manipulate entangled states with both symmetric and asymmetric characteristics, through the dissipation engineering in NH systems.

  We propose a novel generative model, Latent LieGAN, which can discover symmetries of nonlinear group actions. We show that our model can express nonlinear symmetries under some conditions about the group action. LaLiGAN also results in a well-structured latent space that is useful for downstream tasks including equation discovery and long-term forecasting.

• Symmetry-Protected Scattering in Non-Hermitian Linear Systems [0.0]
  The symmetry-protected scattering in non-Hermitian linear systems is investigated by employing the discrete symmetries that classify the random matrices. The odd-parity symmetries including the particle-hole symmetry, chiral symmetry, and sublattice symmetry cannot ensure the scattering to be symmetric. Our findings provide fundamental insights into symmetry and scattering ranging from condensed matter physics to quantum physics and optics.

We argue that the usual representation of the scattering wave function does not account for insufficient account for a proper description of the underlying potential symmetries.
