T-duality invariant approaches to string theory [PDF]
PhDThis thesis investigates the quantum properties of T-duality invariant formalisms of String Theory. We introduce and review duality invariant formalisms of String Theory including the Doubled Formalism.

Coordinate and Kähler σ-model anomalies and their cancellation in string effective field theories [PDF]
We discuss the complete set of one-loop triangle graphs involving the Yang-Mills gauge connection, the \Kahler\ connection and the $σ$-model coordinate connection in the effective field theory of $(2,2)$ symmetric $Z_N$ orbifolds. That is, we discuss pure gauge, pure \Kahler\ and pure $σ$-model coordinate anomalies as well as the mixed anomalies, such ...

We study nondissipative transport induced by the Nieh-Yan anomaly. After computing the torsional terms in the equilibrium partition function using transgression, we find the constitutive relations for the covariant axial-vector, heat, stress, and spin ...

Chiral kinetic theory from effective field theory revisited
We revisit the chiral kinetic equation from high density effective theory approach, finding a chiral kinetic equation differs from counterpart derived from field theory in high order terms in the O(1/μ) expansion, but in agreement with the equation ...

BRST-BFV analysis of anomalies in bosonic string theory interacting with background gravitational field [PDF]
The general BRST-BFV analysis of anomaly in the string theory coupled to background fields is carried out. An exact equation for c-valued symbol of anomaly operator is found and structure of its solutions is studied.

Zilch vortical effect for fermions
We consider the notion of zilch current that was recently discussed in the literature as an alternative helicity measure for photons. Developing this idea, we suggest the generalization of the zilch for the systems of fermions.

On the associativity anomaly in open string field theory
Abstract The associativity anomaly in the star algebra of the open bosonic string is demonstrated by a simple oscillator calculation. In an associative algebra, formal arguments require that the “half string” BRST operator QL be nilpotent; however, we show that associativity is actually violated by computing QL2 in an explicit operator representation

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

On loop corrections to string effective field theories: field-dependent gauge couplings and σ-model anomalies [PDF]
Abstract We show that certain one-loop corrections to superstring effective four-dimensional lagragians, involving non-harmonic field-dependent renormalization of gauge couplings, can be consistently written in a standard N = 1 supergravity form, preserving target-space duality.
