Advanced Engineering Materials, EarlyView.This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Exploring the unification of quantum theory and general relativity with a Bose–Einstein condensate
New Journal of Physics, 2019 Despite almost a century’s worth of study, it is still unclear how general relativity (GR) and quantum theory (QT) should be unified into a consistent theory.

Leggett-Garg macrorealism and the quantum nondisturbance conditions
, 2019 We investigate the relation between a refined version of Leggett and Garg conditions for macrorealism, namely the no-signaling-in-time (NSIT) conditions, and the quantum mechanical notion of nondisturbance between measurements.

Advanced Functional Materials, EarlyView.In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Relativity and quantum theory. A unified model [PDF]
Annali di Matematica Pura ed Applicata, 1969 By considering a distribution of complex basic spinors \(W\), satisfying the invariant linear differential equation \(\operatorname{curl}_5 W = 0\) in a 5-dimensional Kaluza space such that the space curvatures are determined by the concomitants of the spinors, a precisely defined mathematical model is obtained.

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Single-mode approximation and effective Chern-Simons theories for quantum Hall systems
, 2004 A unified description of elementary and collective excitations in quantum Hall systems is presented within the single-mode approximation (SMA) framework, with emphasis on revealing an intimate link with Chern-Simons theories.
