Global anomalies in 8d supergravity
Journal of High Energy Physics, 2022 We study gauge and gravitational anomalies of fermions and 2-form fields on eight-dimensional spin manifolds. Possible global gauge anomalies are classified by spin bordism groups Ω 9 spin BG $$ {\varOmega}_9^{\mathrm{spin}}(BG) $$ which we determine by ...

Trace and chiral anomalies in string and ordinary field theory from Feynman diagrams for non-linear sigma models [PDF]
Nuclear Physics B, 1998 We write general one-loop anomalies of string field theory as path integrals on a torus for the corresponding nonlinear sigma model. This extends the work of Alvarez-Gaumé and Witten from quantum mechanics to two dimensions. Higher world-volume loops contribute in general to nontopological anomalies and a formalism to compute these is developed.

Translations as inner derivations and associativity anomalies in open string field theory
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 1987 Abstract We show that spacetime translations are inner derivations of Witten's star algebra for open bosonic string field theory. The connection between inner derivations and gauge transformations is discussed. This result is in conflict with the naive expectation that the string midpoint is fixed in the star algebra.

Associativity anomaly in string field theory [PDF]
Physical Review D, 2002 We give a detailed study of the associativity anomaly in open string field theory from the viewpoint of the split string and Moyal formalisms. The origin of the anomaly is reduced to the properties of the special infinite size matrices which relate the conventional open string to the split string variables, and is intimately related to midpoint issues.

Witten effect, anomaly inflow, and charge teleportation
Journal of High Energy Physics, 2021 We study a phenomenon that electric charges are “teleported” between two spatially separated objects without exchanging charged particles at all. For example, this phenomenon happens between a magnetic monopole and an axion string in four dimensions, two

Anomalies in Witten's field theory of the NSR string [PDF]
Physics Letters B, 1988 Abstract We show that Witten's action for the NSR superstring on the space of non-smooth vectors generated by SUSY transformations depends on regularization that demonstrates the presence of anomalies in the theory. The necessity of choosing the regularization is connected with the appearance of the product of picture-changing operators at coincident

Comments on QCD3 and anomalies with fundamental and adjoint matter
Journal of High Energy Physics, 2022 ’t Hooft anomaly matching is powerful for constraining the low energy phases of gauge theories. In 3d one common anomaly is the parity anomaly in a T-symmetric theory where one cannot gauge the global symmetry group without breaking the time-reversal ...

Boundary string current & Weyl anomaly in six-dimensional conformal field theory [PDF]
Journal of High Energy Physics, 2019 AbstractIt was recently discovered that for a boundary system in the presence of a background magnetic field, the quantum fluctuation of the vacuum would create a non-uniform magnetization density for the vacuum and a magnetization current is induced in the vacuum [1].

Chiral torsional effects in anomalous fluids in thermal equilibrium
Journal of High Energy Physics, 2021 Using the similarity between spacetime torsion and axial gauge couplings, we study torsional contributions to the equilibrium partition function in a stationary background.
