Two-Time Physics in Field Theory [PDF]
, 2000 A field theory formulation of two-time physics in d+2 dimensions is obtained from the covariant quantization of the constraint system associated with the OSp(n|2) worldline gauge symmetries of two-time physics.

An inverse mass expansion for the mutual information in free scalar QFT at finite temperature
Journal of High Energy Physics, 2020 We study the entanglement entropy and the mutual information in coupled harmonic systems at finite temperature. Interestingly, we find that the mutual information does not vanish at infinite temperature, but it rather reaches a specific finite value ...

Entanglement entropy from entanglement contour: higher dimensions [PDF]
SciPost Physics Core, 2019 We study the entanglement contour and partial entanglement entropy (PEE) in quantum field theories in 3 and higher dimensions. The entanglement entropy is evaluated from a certain limit of the PEE with a geometric regulator.

Self-Duality and New TQFTs for Forms [PDF]
, 1998 We discuss theories containing higher-order forms in various dimensions. We explain how Chern--Simons-type theories of forms can be defined from TQFTs in one less dimension.

Solving the 3D Ising Model with the Conformal Bootstrap [PDF]
, 2012 We study the constraints of crossing symmetry and unitarity in general 3D Conformal Field Theories. In doing so we derive new results for conformal blocks appearing in four-point functions of scalars and present an efficient method for their computation ...

Constraining conformal field theory with higher spin symmetry in four dimensions [PDF]
Nuclear Physics B, 2013 We analyze the constraints on the general form and the singularity structure of the correlation functions of the symmetric, traceless and conserved stress-energy tensor implied by conformal invariance and higher spin symmetry in four dimensions. In particular, we show that all these correlation functions will have at most double pole singularities.

Biharmonic Conformal Field Theories [PDF]
, 1995 The main result of this paper is the construction of a conformally covariant operator in two dimensions acting on scalar fields and containing fourth order derivatives. In this way it is possible to derive a class of Lagrangians invariant under conformal

Light scalars on cosmological backgrounds
Journal of High Energy Physics, 2018 We study the behaviour of a light quartically self-interacting scalar field ϕ on curved backgrounds that may be described with the cosmological equation state parameter w.

Metric- and frame-like higher-spin gauge theories in three dimensions [PDF]
, 2014 We study the relation between the frame-like and metric-like formulation of higher-spin gauge theories in three space–time dimensions. We concentrate on the theory that is described by an SL ( 3 ) × SL ( 3 ) ?> Chern–Simons theory in the frame-like ...
