Directional memory of early spectral selection during spinodal decomposition in finite systems
Boliang Yu, Ruixin Zhou, Zheng Zhang
Cahn-Hilliard phase separation turns small composition fluctuations into coarsening domains. In Fourier space, the pattern forms a ring whose angular intensity favors an axis. We a…
Hidden amplitude and dynamical information in phase-separation spectra
Boliang Yu, Ruixin Zhou, Jiaxing Yuan
Framewise variance normalization removes fluctuation amplitude from an observation, but not from the dynamics that generate later patterns. The current normalized spectrum therefor…
Observable dependence and rate identifiability in false-vacuum decay of the quantum Ising chain
Boliang Yu, Ruixin Zhou, Hang Su
Extracting a thermodynamic nucleation rate from finite-time quantum dynamics requires separating observable decay from estimator and finite-size validity. We develop a multilevel i…
Entanglement spectrum ordering and flavor polarization in the two-flavor Schwinger model at vacuum angle
Boliang Yu, Ruixin Zhou, Meisen Gao
Entanglement spectra in gauge theories can encode both symmetry breaking and the organization of gauge sectors. In the two-flavor Schwinger model at vacuum angle , we find tha…
