TBA equations and resurgent Quantum Mechanics
We derive a system of TBA equations governing the exact WKB periods in one-dimensional Quantum Mechanics with arbitrary polynomial potentials. These equations provide a generalization of the ODE/IM correspondence, and they can be regarded as the solution

Effective Quantum Field Theory for the Thermodynamical Bethe Ansatz
We construct an effective Quantum Field Theory for the wrapping effects in 1+1 dimensional models of factorised scattering. The recently developed graph-theoretical approach to TBA gives the perturbative desctiption of this QFT.

Homological classification of topological terms in sigma models on homogeneous spaces
We classify the topological terms (in a sense to be made precise) that may appear in a non-linear sigma model based on maps from an arbitrary worldvolume manifold to a homogeneous space G/H (where G is an arbitrary Lie group and H ⊂ G).

Exotic field theories for (hybrid) fracton phases from imposing constraints in foliated field theory
Fracton phases of matter are gapped phases of matter that, by dint of their sensitivity to UV data, demand non-standard quantum field theories to describe them in the IR. Two such approaches are foliated quantum theory and exotic field theory.

SPIN TOPOLOGICAL QUANTUM FIELD THEORIES [PDF]
Starting from the quantum group [Formula: see text], we construct operator invariants of 3-cobordisms with spin structure, satisfying the requirements of a topological quantum field theory and refining the Reshetikhin–Turaev and Turaev–Viro models. We establish the relationship between these two refined theories.

From topological to quantum entanglement
Entanglement is a special feature of the quantum world that reflects the existence of subtle, often non-local, correlations between local degrees of freedom. In topological theories such non-local correlations can be given a very intuitive interpretation:

PARTICLE CONTENT IN TOPOLOGICAL FIELD THEORIES [PDF]
By demanding that the path-integral measure of the topological field theories be metric-independent, we can derive powerful constraints on the particle content of a topological field theory as well as on the dimensionality of space-time. We also relate this metric independence to the number of degrees of freedom in the theory.

Twistor constructions for higher-spin extensions of (self-dual) Yang-Mills
We present the inverse Penrose transform (the map from spacetime to twistor space) for self-dual Yang-Mills (SDYM) and its higher-spin extensions on a flat background.
