Anomalous dimensions of partially conserved higher-spin currents from conformal field theory: Bosonic ϕ2n theories [PDF]

Physical Review D
In the free □k scalar conformal field theory, there exist conserved and partially conserved higher-spin currents. We study their anomalous dimensions associated with ϕ2n interaction in the ε expansion. We derive general formulas for the leading corrections from the conformal multiplet recombination, and verify their consistency with crossing symmetry ...

Logarithmic negativity in quantum Lifshitz theories

Journal of High Energy Physics, 2020
We investigate quantum entanglement in a non-relativistic critical system by calculating the logarithmic negativity of a class of mixed states in the quantum Lifshitz model in one and two spatial dimensions.

p-form electrodynamics as edge modes of a topological field theory

Journal of High Energy Physics, 2023
p-form electrodynamics in d ≥ 2 dimensions is shown to emerge as the edge modes of a topological field theory with a precise set of boundary conditions, through the Hamiltonian reduction of its action.

Off-shell CHY amplitudes and Feynman graphs

Journal of High Energy Physics, 2020
A polynomial form is established for the off-shell CHY scattering equations proposed by Lam and Yao. Re-expressing this in terms of independent Mandelstam invariants provides a new expression for the polynomial scattering equations, immediately valid off

Yang-Mills, Gravity, and String Symmetries [PDF]

, 1996
In this work we use constructs from the dual space of the semi-direct product of the Virasoro algebra and the affine Lie algebra of a circle to write a theory of gravitation which is a natural analogue of Yang-Mills theory. The theory provides a relation

One-loop CHY-integrand of bi-adjoint scalar theory

Journal of High Energy Physics, 2020
In this paper, the one-loop CHY-integrands of bi-adjoint scalar theory has been reinvestigated. Differing from previous constructions, we have explicitly removed contributions from tadpole and massless bubbles when taking the forward limit of ...

From locality to irregularity: introducing local quenches in massive scalar field theory

Journal of High Energy Physics, 2023
In this paper, we initiate the study of operator local quenches in non-conformal field theories. We consider the dynamics of excited local states in massive scalar field theory in an arbitrary spacetime dimension and generalize the well-known two ...

Entanglement of harmonic systems in squeezed states

Journal of High Energy Physics, 2023
The entanglement entropy of a free scalar field in its ground state is dominated by an area law term. It is noteworthy, however, that the study of entanglement in scalar field theory has not advanced far beyond the ground state.

Noncommutative Sp(2,R) Gauge Theories - A Field Theory Approach to Two-Time Physics [PDF]

, 2001
Phase-space and its relativistic extension is a natural space for realizing Sp(2,R) symmetry through canonical transformations. On a Dx2 dimensional covariant phase-space, we formulate noncommutative field theories, where Sp(2,R) plays a role as either a
