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

Two-point functions and bootstrap applications in quantum field theories [PDF]
Journal of High Energy Physics, 2020 We study two-point functions of local operators and their spectral representation in UV complete quantum field theories in generic dimensions focusing on conserved currents and the stress-tensor.

Oscillons in higher-derivative effective field theories [PDF]
Physical Review D, 2018 We investigate the existence and behavior of oscillons in theories in which higher derivative terms are present in the Lagrangian, such as galileons.

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
