Experimental Comparison of Bohm-like Theories with Different Primary Ontologies [PDF]
The de Broglie-Bohm theory is a hidden-variable interpretation of quantum mechanics which involves particles moving through space along deterministic trajectories. This theory singles out position as the primary ontological variable.

Momentum transfer in gravitation theory
An inductive flux of gravitational momentum in Newtonian theory, and a radiative flux of gravitational momentum in general relativity, while being physically dissimilar quantities, are shown to be formally equivalent by expressing them in terms of a symplectic form on the solution space of the respective field equations.

The momentum kernel of gauge and gravity theories [PDF]
We derive an explicit formula for factorizing an $n$-point closed string amplitude into open string amplitudes. Our results are phrased in terms of a momentum kernel which in the limit of infinite string tension reduces to the corresponding field theory kernel.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

On Equivalence of Definition of the Energy-Momentum Tensor in General Relativity and Field Theory [PDF]
This work investigates a fundamental pedagogical question concerning the definition of the energy-momentum tensor in theoretical physics. Students learn the definition of energy-momentum tensor in the field theory and on the other hand a different ...

We consider non-Abelian SU(3) Proca theory with a Higgs scalar field included. Cylindrically symmetric solutions describing classical tubes either with the flux of a longitudinal electric field or with the energy flux (and hence with nonzero momentum ...

A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Information Uncertainty and the Momentum Effect [PDF]
I identify simple proxies for uncertainty and attempt to determine if the returns to a momentum strategy vary with these proxies. The proxies identified include the stock’s daily 6-month historical return volatility, the magnitude of alpha in a 6-month ...
