Experience and Time: A Metaphysical Approach

Analytic Philosophy, EarlyView.
ABSTRACT What is the temporal structure of conscious experience? While it is popular to think that our most basic conscious experiences are temporally extended, we will be arguing against this view, on the grounds that it makes our conscious experiences depend on the future in an implausible way.

4D spherically symmetric time-dependent quantum gravity amplitudes

European Physical Journal C: Particles and Fields
In these short notes, we compute non-perturbatively the time-dependent quantum gravity amplitudes for a four-dimensional spherically symmetric space-time with space-like and time-like boundaries.

Holographic signatures of resolved cosmological singularities

Journal of High Energy Physics, 2019
The classical gravity approximation is often employed in AdS/CFT to study the dual field theory, as it allows for many computations. A drawback is however the generic presence of singularities in classical gravity, which limits the applicability of AdS ...

Discriminating quantum gravity models by gravitational decoherence

Nuclear Physics B, 2023
Several phenomenological approaches to quantum gravity predict the existence of a minimal measurable length and/or a maximum measurable momentum near the Planck scale.

A New Padé Approach to Modeling Wormholes in Dekel‐Zhao Dark Matter Halos

Annalen der Physik, Volume 538, Issue 3, March 2026.
A matter‐first Padé strategy is introduced to build traversable wormholes from prescribed dark‐matter halos. Rational Padé fits approximately the Dekel–Zhao density and are analytically integrated to obtain a shape function that exactly reproduces the intended matter content, avoiding spurious poles of geometry‐first schemes.

An Alternative Approach to Spontaneous Photon Triplets Generation

Advanced Physics Research, Volume 5, Issue 3, March 2026.
Day by day, communication and computing technologies are progressing at a lightning speed, which is particularly true of the quantum version of these technologies (QIST). Increasingly, these technologies are emerging from unusual and sometimes bewildering quantum optical effects, which are based on exotic quantum physical theories.

Turn‐Induction in Peptides Incorporating Novel Cyrene‐Derived α,α‐Disubstituted Amino Acid

Journal of Peptide Science, Volume 32, Issue 3, March 2026.
Novel chiral cyrene‐derived Cyr residues were incorporated into peptides. The α,α‐disubstituted amino acid residue was introduced using the Ugi reaction. X‐ray crystallographic analysis of R‐ and S‐Cyr residues indicated preference to adopt left‐ and right‐handed α‐helical conformations, respectively.
