Some aspects of QFT in non-inertial frames

Nuclear Physics B
Some aspects of quantum field theory in a general (i.e. non inertial) frame of Minkowski spacetime are studied. Conditions for the presence of horizons as well as for the modification of the definition of positive energy solutions are examined.

Existence conditions of framed curves for smooth curves

Existence conditions of framed curves for smooth curves
A framed curve is a smooth curve in the Euclidean space with a moving frame. We call the smooth curve in the Euclidean space the framed base curve. In this paper, we give an existence condition of framed curves. Actually, we construct a framed curve such that the image of the framed base curve coincides with the image of a given smooth curve under a ...

Structural analysis of helically coiled once-through steam generator tubes in small modular reactors under density wave oscillation—part I: Numerical formulation

Nuclear Engineering and Technology
This study establishes a numerical framework to evaluate the structural integrity of helically coiled once-through steam generator (H-OTSG) tubes in small modular reactors (SMRs) under density wave oscillation (DWO).

Third-order relativistic fluid dynamics at finite density in a general hydrodynamic frame

European Physical Journal C: Particles and Fields
The motion of water is governed by the Navier–Stokes equations, which are complemented by the continuity equation to ensure local mass conservation.
