From polymer to SiOC glass: structure, microstructure, mechanical, and thermal properties

open access: yesJournal of the American Ceramic Society, EarlyView.
Abstract The transformation of a methyl‐siloxane into a SiOC glass in Ar and reactive CO2 atmosphere was studied through positron annihilation spectroscopy, infrared spectroscopy, density, and calorimetric measurements, whereas the mechanical properties were monitored by nanoindentation and the thermal diffusivity measured by the laser flash method ...

Search for heavy resonances in final states with four leptons and missing transverse momentum or jets in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for a new heavy boson produced via gluon-fusion in the four-lepton channel with missing transverse momentum or jets is performed. The search uses proton-proton collision data equivalent to an integrated luminosity of 139 fb −1 at a centre-of ...

Introduction to bosonization [PDF]

open access: yesBrazilian Journal of Physics, 2003
This is a pedagogical introduction to the general technique of bosonization of one-dimensional systems starting from scratch and assuming very little besides basic quantum mechanics and second quantization. The formalism is developed in a self-contained fashion and applied to the spinless and spin- Luttinger models, working out both single and two ...

What physicalism could be

open access: yesAnalytic Philosophy, EarlyView.
Abstract The physicalist credo is that the world is physical. But some phenomena, such as minds, morals, and mathematics, appear to be nonphysical. While an uncompromising physicalism would reject these, a conciliatory physicalism need not if it can account for them in terms of an underlying physical basis.

Hunting for Paradoxes: A Research Strategy for Cognitive Science

open access: yesTopics in Cognitive Science, EarlyView.
Abstract How should we identify interesting topics in cognitive science? This paper suggests that one useful research strategy is to hunt for, and attempt to resolve, paradoxes: that is, apparent or real contradictions in our understanding of the mind and of thought.

Search for the Decay of the Higgs Boson to Charm Quarks with the ATLAS Experiment.

open access: yesPhysical Review Letters, 2018
A direct search for the standard model Higgs boson decaying to a pair of charm quarks is presented. Associated production of the Higgs and Z bosons, in the decay mode ZH→ℓ^{+}ℓ^{-}cc[over ¯] is studied.

Magnetization and Polarization of Coupled Nuclear Spins Ensembles at High Magnetic Fields

open access: yesChemPhysChem, Volume 26, Issue 13, July 2, 2025.
Herein, the magnetization of spins at high magnetic fields using various theoretical approaches is analyzed. The theorem is rigorously proved that the magnetization of individual spins is equivalent to the magnetization of coupled spins within a molecule.

A heavy neutral gauge boson near the Z boson mass pole via third generation fermions at the LHC

open access: yesPhysics Letters B, 2020
We explore the physics of a new neutral gauge boson, (Z′), coupling to only third-generation particles and with a mass near the electroweak gauge boson mass poles. A Z′ boson produced by top quarks and decaying to tau leptons is considered. With a simple

Highly Off‐Centering Cations in Pavonite‐Structured Ag1.75InSb5.75Se11 with Competitive Thermoelectric Performance

open access: yesAdvanced Functional Materials, Volume 35, Issue 27, July 3, 2025.
Off‐centering of cations in pavonite‐structured Ag1.75InSb5.75Se11 (AISS) breaks crystal symmetry, inducing Rashba‐like band splitting and high band degeneracy, thus enhancing Seebeck coefficients. Soft bonds between off‐centered cations and Se atoms increase phonon scattering, achieving low lattice thermal conductivity (0.22 W m−1K−1 at 723 K). Doping
