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 ...

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.

Modular energy inequalities from relative entropy
Journal of High Energy Physics, 2018 We obtain new constraints for the modular energy of general states by using the monotonicity property of relative entropy. In some cases, modular energy can be related to the energy density of states and these constraints lead to interesting relations ...

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

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.

Higher Dimensional Analogues of Donaldson-Witten Theory [PDF]
, 1997 We present a Donaldson-Witten type field theory in eight dimensions on manifolds with $Spin(7)$ holonomy. We prove that the stress tensor is BRST exact for metric variations preserving the holonomy and we give the invariants for this class of variations.

Dimensionally continued Oppenheimer-Snyder gravitational collapse II: solutions in odd dimensions [PDF]
, 1999 The Lovelock gravity extends the theory of general relativity to higher dimensions in such a way that the field equations remain of second order. The theory has many constant coefficients with no a priori meaning.

Compactifying 5d superconformal field theories to 3d
Journal of High Energy Physics, 2021 Building on recent progress in the study of compactifications of 6d (1, 0) superconformal field theories (SCFTs) on Riemann surfaces to 4d N $$ \mathcal{N} $$ = 1 theories, we initiate a systematic study of compactifications of 5d N $$ \mathcal{N} $$ = 1

Vertex Algebras in Higher Dimensions and Globally Conformal Invariant Quantum Field Theory [PDF]
Communications in Mathematical Physics, 2004 We propose an extension of the definition of vertex algebras in arbitrary space-time dimensions together with their basic structure theory. An one-to-one correspondence between these vertex algebras and axiomatic quantum field theory (QFT) with global conformal invariance (GCI) is constructed.

Higher-dimensional conformal field theories in the Coulomb branch [PDF]
, 2010 We use the AdS/CFT correspondence to study flows of N = 4 SYM to non-conformal theories. The dual geometries can be seen as sourced by a Wigner's semicircle distribution of D3 branes.
