Author(s): L. Nimmesgern, M. Cygorek, A. Mielnik-Pyszczorski, D. E. Reiter, A. Vagov, and V. M. AxtIf a two-level system coupled to a single-mode cavity is strongly driven by an external laser, instead of a continuous accumulation of photons in the cavity, oscillations in the mean photon number occur. These oscillations correspond to peaks of finite...
Author(s): Maria Vittoria Gurrieri, Emil V. Denning, Kristian Seegert, Philip T. Kristensen, and Jesper MørkWe present a comprehensive investigation of the light-matter interaction dynamics in two-dimensional materials coupled with a spectrally isolated cavity mode in the strong coupling regime. The interaction between light and matter breaks the translational...
Author(s): C. E. A. Barker, K. Fallon, C. Barton, E. Haltz, T. P. Almeida, S. Villa, C. Kirkbride, F. Maccherozzi, B. Sarpi, S. S. Dhesi, D. McGrouther, S. McVitie, T. A. Moore, O. Kazakova, and C. H. MarrowsIn synthetic antiferromagnets (SAFs), antiferromagnetic (AFM) order and synthesis using conventional sputtering techniques is combined to produce...
Author(s): Niklas Scheuler, Patric Rommel, Jörg Main, and Pavel A. BelovRydberg excitons are the solid-state analogs of Rydberg atoms and can, e.g., for cuprous oxide, easily reach a large size in the region of µm for principal quantum numbers up to n=25. The fabrication of quantum welllike structures in the crystal leads to quantum confinement effects...
Author(s): Yusuke O. Nakai, Nobuyuki Okuma, Daichi Nakamura, Kenji Shimomura, and Masatoshi SatoThis paper introduces scalar measures that adequately characterize the non-Hermitian skin effects under open boundary condition. Using these measures, the authors reveal that the topological properties of the non-Hermitian skin effect give a macroscopic enhancement...
Author(s): Kui Cao and Su-Peng KouWe show that many-body fermionic non-Hermitian systems require two distinct sets of topological invariants to describe the topology of energy bands and quantum states, respectively, with the latter yet to be explored. We identify 10 symmetry classes—determined by particle-hole, linearized time-rever… [Phys. Rev. B 109,...
