Spin Polarized Quasi-particle in Off-equilibrium Medium
Shu Lin, Jiayuan Tian
It is usually believed that physics in off-equilibrium state characterized by hydrodynamic gradient can be equivalently studied using equilibrium state with suitable metric perturb…

In-medium Electromagnetic Form Factors and Spin Polarizations
Shu Lin, Jiayuan Tian
We formulate the coupling between fermion spin and background electromagnetic fields using form factors. We show that the vacuum form factors at tree level reproduce the spin polar…

Medium Correction to Gravitational Form Factors
Shu Lin, Jiayuan Tian
We generalize the gravitational form factor for chiral fermion in vacuum, which reproduces the well-known spin-vorticity coupling. We also calculate radiative correction to the gra…
