Abstract: Many-body systems with chiral fermions exhibit anomalous transport phenomena originated from quantum anomalies. Based on quantum field theory, we derive the kinetic theory for chiral fermions interacting with an external electromagnetic field and a background… read more here.

Abstract: In quantum-field theory in curved spacetime, two important physical quantities are the expectation value of the stress-energy tensor 〈Tμν〉 and of the square of the field operator 〈φ2〉. These expectation values must be renormalized, which… read more here.
