Strain Partitioning at the Oxide Interface for the Isothermal Phase Transition in Freestanding Tri‐Layers

open access: yesAdvanced Functional Materials, EarlyView.
The metal–insulator transition temperature (TMI) is continuously tuned by the systematic change of relative thickness in VO2 and TiO2 films (tVO2/tTiO2${t_{{\mathrm{V}}{{\mathrm{O}}_2}}}/{t_{{\mathrm{Ti}}{{\mathrm{O}}_2}}}$) in freestanding TiO2/VO2/TiO2 tri‐layers.

Enhanced Electromechanical Response in 1D Hybrid Perovskites: Coexistence of Normal and Relaxor Ferroelectric Phases

open access: yesAdvanced Functional Materials, EarlyView.
The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Do atoms age?

open access: yesPhysics Letters B, 2022
Time evolution generically entangles a quantum state with environmental degrees of freedom. The resulting increase in entropy changes the properties of that quantum system leading to “aging”.

Effects of Temperature Annealing on the Intrinsic Transport Mechanisms of Solution Processed Graphene Nanosheet Networks

open access: yesAdvanced Functional Materials, EarlyView.
Unravelling charge transport mechanisms in graphene nanosheet networks: by combining temperature‐dependent conductivity measurements with a Random Resistor Network model, this study identifies a transition from hopping‐dominated conduction to a band‐like transport mechanism.

Quantum-classical mechanics as an alternative to quantum mechanics in molecular and chemical physics

open access: yesHeliyon, 2019
In quantum mechanics, the theory of quantum transitions is grounded on the convergence of a series of time-dependent perturbation theory. In nuclear and atomic physics, this series converges because the dynamics of quantum transitions (quantum jumps) are

The ineffable now in physics [PDF]

open access: yes
While physicists know how to use quantum mechanics, there is no consensus on what quantum mechanics is a mechanics of. The aim of this paper is to introduce the beginning of what might turn out to be an interpretation of quantum mechanics—one that leaves
