Exploring $U_A(1)$ symmetry restoration in a magnetic field by meson screening masses in the NJL model

We investigate the effective axial $U_A(1)$ symmetry restoration at finite temperature in an external magnetic field using meson screening masses, as well as meson susceptibilities, in a $(2+1)$-flavor Nambu-Jona-Lasinio (NJL) model. To incorporate inverse magnetic catalysis, we employ a magnetic-field-dependent four-q...

Magnetic thresholds and spin-resolved spectral moments of $\phi$ and $K^{*0}$ in a hadronic model

We study the spin-resolved spectral functions of $\phi$ and $K^{*0}$ in a thermal hadronic model with a constant magnetic field. We construct the rest-frame retarded propagators by combining real vacuum matching with exact Landau levels, connection contacts, and thermal scattering terms. The resulting stable-daughter c...

Corporate Climate Risk Attention and Carbon Lock-In: Sustainable Decarbonization Pathways in an Era of Climate Extremes

Climate extremes and the accelerating low-carbon transition have intensified firms’ exposure to physical and transition risks, yet many firms remain constrained by carbon-intensive development paths. Using panel data for Chinese A-share listed firms from 2013 to 2024, we examine the relationship between corporate clima...
