Enhancement of anomalous boundary current by high temperature

Recently it is found that Weyl anomaly leads to novel anomalous currents in the spacetime with a boundary. However, current suppressed by mass of charge carriers and distance boundary, which makes difficult be measured. In this paper, we explore possible mechanisms for enhancement currents. Interestingly, find can significantly enhanced high temperature, easier experimental detection. For free theories, proportional temperature limit. Note thermal effects only at temperatures. general, not case low general temperatures, absolute value Neumann boundary condition first decreases then increases while Dirichlet always temperature. It should mentioned does have an nature. fact, so-called paper related anomaly. Instead, effect due
