Relating ’t Hooft anomalies of 4d pure Yang-Mills and 2d ℂℙ N− 1 model

Journal of High Energy Physics, 2018
It has recently been shown that a center-twisted compactification of the four-dimensional pure SU(N) Yang-Mills theory on a three-torus gives rise to the twodimensional ℂℙ N− 1-model on a circle with a flavor-twisted boundary condition.

Relativistic hydrodynamics with the parity anomaly

Journal of High Energy Physics, 2022
We consider the hydrodynamic regime of a 2+1 dimensions QFT with the parity anomaly. Beyond the known constraints from positivity of entropy production, we show that the anomaly inflow mechanism, from a corresponding bulk SPT phase, together with ...

Topics in Supersymmetry Breaking and Gauge/Gravity Dualities [PDF]

, 2010
The thesis covers two topics in string theory and quantum field theory. First, we realize metastable vacua in various supersymmetric gauge theories. Specifically, we consider the Coulomb branch of any N = 2 supersymmetric gauge theory, and perturb it by ...

Dynamical Abelianization and anomalies in chiral gauge theories

Journal of High Energy Physics, 2022
We explore the idea that in some class of strongly-coupled chiral SU(N) gauge theories the infrared dynamics might be characterized by a bifermion condensate in the ad- joint representation of the color gauge group.

Jacobi Identity Anomaly in Closed String Field Theory [PDF]

Progress of Theoretical Physics, 1991
The Jacobi identity, which is an indispensable property for gauge invariant closed string field theory, is apparently broken in cases where one of the four legs of the identity has vanishing string-length. This phenomenon contradicts the general proof of the identity valid at the critical dimension.

The consistency of topological expansions in field theory: “BRST anomalies” in strings and Yang-Mills [PDF]

Nuclear Physics B, 1994
Many field theories of physical interest have configuration spaces consisting of disconnected components. Quantum mechanical amplitudes are then expressed as sums over these components. We use the Faddeev-Popov approach to write the terms in this topological expansion as moduli space integrals. A cut-off is needed when these integrals diverge.

Mirror Symmetry and Other Miracles in Superstring Theory [PDF]

, 2010
The dominance of string theory in the research landscape of quantum gravity physics (despite any direct experimental evidence) can, I think, be justified in a variety of ways.

Chiral anomalous dispersion

Journal of High Energy Physics, 2018
The linearized Einstein equation describing graviton propagation through a chiral medium appears to be helicity dependent. We analyze features of the corresponding spectrum in a collision-less regime above a flat background. In the long wave-length limit,

Quantum kinetic equation for fluids of spin-1/2 fermions

Journal of High Energy Physics, 2021
Fluid of spin-1/2 fermions is represented by a complex scalar field and a four-vector field coupled both to the scalar and the Dirac fields. We present the underlying action and show that the resulting equations of motion are identical to the ...

SPACETIME OR QUANTUM PARTICLES: THE ONTOLOGY OF QUANTUM GRAVITY? [PDF]

, 1996
The domains of quantum theory and general relativity overlap in situations where quantum mechanical effects cannot be ignored. In order to deal with this overlap of theoretical domains, there has been a tendency to apply the rules of quantum field theory
