Higher Structures in M-Theory [PDF]

, 2018
The key open problem of string theory remains its non-perturbative completion to M-theory. A decisive hint to its inner workings comes from numerous appearances of higher structures in the limits of M-theory that are already understood, such as higher ...

Probing M-theory with tetrahedron instantons

Journal of High Energy Physics, 2023
The duality between type IIA superstring theory and M-theory enables us to lift bound states of D0-branes and n parallel D6-branes to M-theory compactified on an n-centered multi-Taub-NUT space TN $$ \mathbbm{TN} $$ n .

On F-theory effective actions: From anomalies to Swampland [PDF]

, 2019
In this thesis we investigate general properties of four- and six-dimensional effective actions with minimal supersymmetry obtained from F-theory by compactification on Calabi-Yau manifolds.

Instanton Cosmology and Domain Walls from M-theory and String Theory [PDF]

, 1998
The recent proposal by Hawking and Turok for obtaining an open inflationary universe from singular instantons makes use of low-energy effective Lagrangians describing gravity coupled to scalars and non-propagating antisymmetric tensors.

Anisotropic compactification of nonrelativistic M-theory

Journal of High Energy Physics, 2023
We study a decoupling limit of M-theory where the three-form gauge potential becomes critical. This limit leads to nonrelativistic M-theory coupled to a non-Lorentzian spacetime geometry.

Review: Julian Go, ‘Postcolonial Thought and Social Theory’ [PDF]

, 2021
In Julian Go’s pathbreaking text, Postcolonial Thought and Social Theory, he seeks to bridge the seemingly unreconcilable gap between social theory and postcolonial thought.

Macroscopic approaches to rotating neutron stars [PDF]

Ядерна фізика та енергетика
The macroscopic model for a neutron star (NS) as a perfect liquid drop at equilibrium is extended to rotating systems with a small frequency ω within the effective-surface (ES) approach.

Consistent truncations of M-theory for general SU(2) structures [PDF]

, 2015
In seven dimensions any spin manifold admits an SU(2) structure and therefore very general M-theory compactifications have the potential to allow for a reduction to N=4 gauged supergravity. We perform this general SU(2) reduction and give the relation of

Lorentz invariant field theory on κ-Minkowski space [PDF]

, 2010
It is by now well established that the momentum space associated with the non-commutative κ-Minkowski space is a submanifold of de Sitter space. It has been noted recently that field theories built on such momentum space suffer from a subtle form of ...

Bootstrapping M-theory orbifolds

Journal of High Energy Physics
We analyze correlation functions of SU(k) × SU(2) F flavor currents in a family of three-dimensional N $$ \mathcal{N} $$ = 4 superconformal field theories, combining analytic bootstrap methods with input from supersymmetric localization.
