Quantum anomalies from three-point on-shell bootstrap
Hiren Kakkad, Rémy Larue, Rémy Larue +1
We bootstrap quantum anomalies using on-shell techniques in the simplest setting: at three points. The necessary field-theoretic input includes the local or global classical symmet…
Anomalous Transport from Effective Field Theory
Rémy Larue, Amaury Marchon, Jérémie Quevillon +1
A systematic study of chiral effects is presented using an Effective Field Theory framework. By integrating out a massive Dirac fermion at finite temperature in presence of vector…
Examining the Anomalous Nature of Chiral Effects in Thermodynamics
Rémy Larue, Jérémie Quevillon, Diego Saviot
Quantum anomalies give rise to novel transport phenomena, including the generation of a current in a relativistic fluid due to the presence of magnetic field or vorticity. We prese…
Model-independent results on parity violation in the trace anomaly
Rémy Larue, Jérémie Quevillon, Roman Zwicky
Anomalous parity violation in four dimensions would be significant for phenomenology (baryogenesis, gravitational waves) and mathematical physics. Over the past decade, there has b…
Trace Anomaly of Weyl Fermions via the Path Integral
Rémy Larue, Jérémie Quevillon, Roman Zwicky
We compute the trace, diffeomorphism and Lorentz anomalies of a free Weyl fermion in a gravitational background field by path integral methods. This is achieved by regularising the…
Gravity-gauge Anomaly Constraints on the Energy-momentum Tensor
Rémy Larue, Jérémie Quevillon, Roman Zwicky
We derive constraints on the four dimensional energy-momentum tensor from gravitational and gauge anomalies. Our work can be considered an extension of Duff's analysis [1] to inclu…
