Flavor decoherence and washout timing in nonthermal leptogenesis after inflation
Boliang Yu, Ruixin Zhou
We investigate why changing the heavy-neutrino mass hierarchy can reverse the baryon asymmetry in nonthermal leptogenesis after hilltop inflation. Along the mass trajectory studied…
Loading history and window geometry bound compact-state slip ranking during granular shear startup
Ruixin Zhou, Boliang Yu
Granular slip forecasting can conflate material state, loading progress, and the geometry of event-centered sampling. We separated these contributions in slowly sheared two-dimensi…
Movable seams in root-of-unity XXZ chains: Relative flux classes and antiunitary spectral pairing
Boliang Yu, Ruixin Zhou, Meisen Gao
Starting from the cyclic duality tensors introduced by Vernier, Miao, and Yamazaki (VMY), whose endpoint-traced matrix-product operators obey Tambara--Yamagami fusion…
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…
