Advanced Physics Research, Volume 5, Issue 8, August 2026.A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

Advanced Physics Research, Volume 5, Issue 8, August 2026.Quantum Phenomena in Molecular and Biological Systems The front cover shows a luminous arch inscribed with the Lindblad equation, which links quantum waves, molecular structures, and biological networks. The image captures Sarfaraz K. Niazi's decoherence‐based framework for deciding when quantum effects survive, matter, and yield falsifiable ...

Unitarity, feedback, interactions—dynamics emergent from repeated measurements
New Journal of Physics, 2017 Motivated by the recent efforts to describe the gravitational interaction as a classical channel arising from continuous quantum measurements, we study what types of dynamics can emerge from a collisional model of repeated interactions between a system ...

Kondo Screening and Coupling of Spin States on Graphene Nanoribbon
physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 8, August 2026.Coupling of spin states, at the terminus of 7‐AGNR, is manifested by a continuous presence of Kondo resonance across the line profile of the two magnetic sites. This ubiquitous presence of the Kondo effect indicates mediated exchange interactions that may lead to exotic magnetic ordering at the peripheral atoms.

Ultrafast Nonadiabatic Dynamics of Tetraphenyl‐substituted Nitrogen‐Based Heterocycles
Small Structures, Volume 7, Issue 8, August 2026.Two molecules share four phenyl substituents but differ in their core (pyrazine vs. pyrrole), leading to very different emission behavior. One becomes highly emissive upon aggregation, while the other emits similarly in solution and solid states.

Journal of Computational Chemistry, Volume 47, Issue 20, July 30, 2026.Nonadiabatic trajectory simulations unravel the origin of different relaxation times scales observed for two Co(III) complexes, bearing different alkyl groups at their ligands. ABSTRACT Ultrafast excited‐state dynamics of two Co(III) complexes, bearing different alkyl groups (Co1: Methyl, Co2: Ethyl) at the nitrogen of the imidazole ligand, are ...

Does the quantum mechanical wave function exist?
Zagadnienia Filozoficzne w Nauce, 2019 I address the question whether the wave function in quantum theory exists as a real (ontic) quantity or not. For this purpose, I discuss the essentials of the quantum formalism and emphasize the central role of the superposition principle. I then explain
