Twistor constructions for higher-spin extensions of (self-dual) Yang-Mills
Journal of High Energy Physics, 2021 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.

POISSON STRUCTURE INDUCED (TOPOLOGICAL) FIELD THEORIES [PDF]
Modern Physics Letters A, 1994 A class of two-dimensional field theories, based on (generically degenerate) Poisson structures and generalizing gravity-Yang–Mills systems, is presented. Locally, the solutions of the classical equations of motions are given. A general scheme for the quantization of the models in a Hamiltonian formulation is found.

Ising-like and Fibonacci anyons from KZ-equations
Journal of High Energy Physics, 2022 In this work we present solutions to Knizhnik-Zamolodchikov (KZ) equations corresponding to conformal block wavefunctions of non-Abelian Ising-like and Fibonacci Anyons.

Topological conformal field theories and gauge theories
, 2006 This paper gives a construction, using heat kernels, of differential forms on the moduli space of metrised ribbon graphs, or equivalently on the moduli space of Riemann surfaces with boundary.

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

Fermionic SPT phases in higher dimensions and bosonization
Journal of High Energy Physics, 2017 We discuss bosonization and Fermionic Short-Range-Entangled (FSRE) phases of matter in one, two, and three spatial dimensions, emphasizing the physical meaning of the cohomological parameters which label such phases and the connection with higher-form ...

Non-local order parameters and quantum entanglement for fermionic topological field theories
Journal of High Energy Physics, 2020 We study quantized non-local order parameters, constructed by using partial time-reversal and partial reflection, for fermionic topological phases of matter in one spatial dimension protected by an orientation reversing symmetry, using topological ...

Three-dimensional topological insulators and bosonization
Journal of High Energy Physics, 2017 Massless excitations at the surface of three-dimensional time-reversal invariant topological insulators possess both fermionic and bosonic descriptions, originating from band theory and hydrodynamic BF theory, respectively.

Advanced Functional Materials, EarlyView.A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Two-dimensional topological field theories as taffy [PDF]
, 2010 In this paper we use trivial defects to define global taffy-like operations on string worldsheets, which preserve the field theory. We fold open and closed strings on a space X into open strings on products of multiple copies of X, and perform checks ...
