Weak Fragmentation and Thermalization in a Dipole-Conserving Bose-Hubbard Chain

Chenrong Liu

We study Hilbert-space fragmentation and thermalization in a one-dimensional dipole-conserving Bose-Hubbard chain. By analyzing the structure of the Hamiltonian matrix in the Fock…

Photon-Atom Granularity Noise Thermometry

Chen-Rong Liu, Yixuan Wang, Xiaowei Wang +5

We propose granularity noise thermometry (GNT), a fluctuation-based optical thermometry scheme that exploits the intrinsic fluctuations of susceptibility arising from atomic discre…

Granularity Noise Limit in Atomic-Ensemble-Based Metrology

Chen-Rong Liu, Chuang Li, Runxia Tao +4

Conventional noise analysis in atomic-ensemble sensing assumes a continuous-medium approximation, thereby treating the atomic system as a deterministic dielectric. Here, we demonst…
