Quantum electromagnetic stress tensor in an inhomogeneous medium [PDF]
Physical Review D, 2018 Continuing a program of examining the behavior of the vacuum expectation value of the stress tensor in a background which varies only in a single direction, we here study the electromagnetic stress tensor in a medium with permittivity depending on a ...

Gravitational Superenergy Tensor
, 1996 We provide a physical basis for the local gravitational superenergy tensor. Furthermore, our gravitoelectromagnetic deduction of the Bel-Debever-Robinson superenergy tensor permits the identification of the gravitational stress-energy tensor.

Brown-York charges at null boundaries
Journal of High Energy Physics, 2022 The Brown-York stress tensor provides a means for defining quasilocal gravitational charges in subregions bounded by a timelike hypersurface. We consider the generalization of this stress tensor to null hypersurfaces.

Energy Flux Positivity and Unitarity in CFTs [PDF]
, 2010 We show that in most conformal field theories the condition of the energy flux positivity, proposed by Hofman and Maldacena, is equivalent to the absence of ghosts. At finite temperature and large energy and momenta, the two-point functions of the stress

, 2019 We study the spatial distribution of the stress tensor around static quark-anti-quark pair in SU(3) lattice gauge theory. In particular, we reveal the transverse structure of the stress tensor distribution in detail by taking the continuum limit.

The recent tectonic stress field of the Amur region
Геодинамика и тектонофизика, 2018 The Amur region (Priamurie) is located in the NE part of the Amur lithospheric plate and its surrounding territories. Seismic activity is moderate in Priamurie, and the regional earthquakes, including the strongest ones, occur mainly in three seismic ...

A d-dimensional stress tensor for Minkd+2 gravity [PDF]
, 2017 A bstractWe consider the tree-level scattering of massless particles in (d+2)-dimensional asymptotically flat spacetimes. The S$$ \mathcal{S} $$-matrix elements are recast as correlation functions of local operators living on a space-like cut ℳd of the ...

Defining Roles in Pediatric Palliative Care: Perspectives From Oncology and Palliative Care Teams
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Early integration of pediatric palliative care (PPC) is associated with improved symptom management, quality of life, and healthcare utilization for children with cancer. Despite this, variation persists in how PPC is understood, operationalized, and integrated within pediatric oncology programs. In particular, ambiguity surrounding
