Revealing Bosonic Exchange Symmetry in Two-Photon Temporal Wavefunction
Yefeng Mei, Yue Jiang, Shengwang Du
The wavefunction of two identical bosons remains invariant under particle exchange - a fundamental quantum symmetry that underlies Bose-Einstein statistics. We report the direct ex…

Theory of Symmetry-Protected Two-Photon Coherence
Xuanying Lai, Shengwang Du, Yue Jiang
In a recent article [Phys. Rev. Lett. 133, 033601 (2024)], the coherence time of degenerate entangled photon pairs (biphotons) generated via backward spontaneous four-wave mixing i…
