Shape‐Reconfigurable Crack‐Based Strain Sensor with Ultrahigh and Tunable Sensitivity

open access: yesAdvanced Functional Materials, EarlyView.
A highly sensitive crack‐based sensor with tunable strain detection capabilities is demonstrated through controlled nanocrack formation in a line‐patterned shape memory polymer substrate. The sensor design integrates thermoplastic polyurethane and poly(lactic acid), enabling thermo‐responsive reconfiguration of crack geometry.

Near‐Field Phonon Nanoscopy and Imaging of Structural Variants in Mixed Phase BiFeO3

open access: yesAdvanced Functional Materials, EarlyView.
Nano‐Fourier transform infrared spectroscopy and scattering scanning near‐field optical microscopy imaging reveal the phonon response of nanoscale phase variants in mixed‐phase BiFeO3 (BFO). Direct mid‐infrared imaging of associated distinct vibrational signatures is used as a non‐invasive optical detection method for electrical switching of ...

Irreversible quantum graphs

open access: yes, 2003
Irreversibility is introduced to quantum graphs by coupling the graphs to a bath of harmonic oscillators. The interaction which is linear in the harmonic oscillator amplitudes is localized at the vertices.

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions

open access: yesAdvanced Functional Materials, EarlyView.
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

Computational Modeling of Reticular Materials: The Past, the Present, and the Future

open access: yesAdvanced Materials, EarlyView.
Reticular materials are advanced materials with applications in emerging technologies. A thorough understanding of material properties at operating conditions is critical to accelerate the deployment at an industrial scale. Herein, the status of computational modeling of reticular materials is reviewed, supplemented with topical examples highlighting ...

Harmonic oscillator in a background magnetic field in noncommutative quantum phase-space

open access: yes, 2009
We solve explicitly the two-dimensional harmonic oscillator and the harmonic oscillator in a background magnetic field in noncommutative phase-space without making use of any type of representation.

Shell-model calculations for the three-nucleon system [PDF]

open access: yes, 1997
We use Faddeev's decomposition to solve the shell-model problem for three nucleons. The dependence on harmonic-oscillator excitations allowed in the model space, up to $32 \hbar\Omega$ in the present calculations, and on the harmonic-oscillator frequency

A damped harmonic oscillator in the GUP framework

open access: yesIranian Journal of Physics Research, 2019
Harmonic oscillator is significantly important in quantum gravity for its dynamical properties. Dynamics of the harmonic oscillator can be modified by inserting a modified uncertainty relation considered in quantum cosmology models such as string theory ...

Equilibration of a dissipative quantum oscillator [PDF]

open access: yesAnn. Phys. (Leipzig) 16, 319 (2007), 2006
An explicit demonstration is given of a harmonic oscillator in equilibrium approaching the equilibrium of a corresponding interacting system by coupling it to a thermal bath consisting of a continuum of harmonic oscillators.
