Proof of dispersion relations for the amplitude in theories with a compactified space dimension
Journal of High Energy Physics, 2020 The analyticity properties of the scattering amplitude in the nonforward direction are investigated for a field theory in the manifold R 3,1 ⨂ S 1.

Universality of Sparse $d>2$ Conformal Field Theory at Large $N$ [PDF]
, 2017 We derive necessary and sufficient conditions for large $N$ conformal field theories to have a universal free energy and an extended range of validity of the higher-dimensional Cardy formula.

Bosonization in Higher Dimensions via Noncommutative Field Theory
Physical Review Letters, 2006 We propose the bosonization of a many-body fermion theory in D spatial dimensions through a noncommutative field theory on a (2D-1)-dimensional space. This theory leads to a chiral current algebra over the noncommutative space and reproduces the correct perturbative Hilbert space and excitation energies for the fermions.

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 ...

AdS-Wave Solutions of f(Riemann) Theories [PDF]
, 2013 We show that the recently found AdS-plane and AdS-spherical wave solutions of quadratic curvature gravity also solve the most general higher derivative theory in D-dimensions. More generally, we show that the field equations of such theories reduce to an

Odd dimensional nonlocal Liouville conformal field theories
Journal of High Energy Physics, 2022 We construct Euclidean Liouville conformal field theories in odd number of dimensions. The theories are nonlocal and non-unitary with a log-correlated Liouville field, a Q $$ \mathcal{Q} $$ -curvature background, and an exponential Liouville-type ...

Higher-order gravity in higher dimensions: geometrical origins of four-dimensional cosmology? [PDF]
, 2017 Determining the cosmological field equations is still very much debated and led to a wide discussion around different theoretical proposals. A suitable conceptual scheme could be represented by gravity models that naturally generalize Einstein theory ...

Cosmologies with Scalar Fields from Higher Dimensions Applied to Bianchi Type VIh=-1 Model: Classical and Quantum Solutions [PDF]
Advances in High Energy Physics, 2018 We construct an effective four-dimensional model by compactifying a ten-dimensional theory of gravity coupled with a real scalar dilaton field on a time-dependent torus.

BPS solitons in Lifshitz field theories
, 2010 Lorentz-invariant scalar field theories in d+1 dimensions with second-order derivative terms are unable to support static soliton solutions that are both finite in energy and stable for d>2, a result known as Derrick's theorem.

Constraining conformal field theories with a slightly broken higher spin symmetry [PDF]
, 2012 We consider three-dimensional conformal field theories that have a higher spin symmetry that is slightly broken. The theories have a large-N limit in the sense that the operators separate into single trace and multitrace and obey the usual large-N ...
