Assessing the classicality of photon echo from excitons in lead halide perovskite nanocrystals
George Alkhalil, Hendrik Rose, Artur V. Trifonov +9
Photon echo (PE) spectroscopy is a powerful technique for probing decoherence mechanisms and charge carrier dynamics in semiconductor systems. Beyond traditional coherence measurem…
Temporal hopping dynamics in exciton-polariton condensation
Elena Rozas, Wojciech Bukalski, Yannik Brune +9
Polariton condensates provide a versatile platform for exploring non-equilibrium phase transitions and collective phenomena in open quantum systems. Near the condensation threshold…
33 Gbit/s source-device-independent quantum random number generator based on heterodyne detection with real-time FPGA-integrated extraction
Marius Cizauskas, Hamid Tebyanian, Mark Fox +3
We present a high-speed continuous-variable quantum random number generator (QRNG) based on heterodyne detection of vacuum fluctuations. The scheme follows a source-device-independ…
Splitting spin-orbit coupled polariton vortex pairs in the non-Hermitian Rashba-Dresselhaus band at room temperature
Xiaokun Zhai, Ying Gao, Xuekai Ma +6
Spin orbit coupling gives rise to intriguing physical phenomena in bosonic condensates, such as formation of stripe phases and domains with vortex arrays. However, how the non-Herm…
Distinct terahertz third-harmonic generation of many-body excitonic states
Changqing Zhu, Anneke Reinold, Patrick Pilch +6
The dynamics of an electron-hole plasma governed by strong Coulomb interaction is a challenging many-body problem.We report on experimental realization of electron-hole many-body s…
