Quantum decoherence of the damped harmonic oscillator [PDF]

Optics and Spectroscopy, 2007
In the framework of the Lindblad theory for open quantum systems, we determine the degree of quantum decoherence of a harmonic oscillator interacting with a thermal bath. It is found that the system manifests a quantum decoherence which is more and more significant in time.

Deuteron Quadrupole Coupling Constants and Reorientation Correlation Times of Cations in Amino Acid Ionic Liquids

ChemPhysChem, EarlyView.
Connecting structure and dynamics. The deuteron quadrupole coupling constants and reorientation correlation times of the acidic CH bond of imidazolium cations in amino acid ionic liquids are provided by using NMR property relationships and relaxation time experiments.

The quartic anharmonic oscillator - an oscillator-basis expansion approach. I. Energy levels study and calculation [PDF]

Ядерна фізика та енергетика
For the quantum quartic anharmonic oscillator with the Hamiltonian H=0.5(p2+x2)+λx4 which is one of the classic traditional quantum-mechanical and quantum-field-theory models, its main physical characteristics and properties are thoroughly studied and ...

Atomistic Modeling of Methyl Formate and Glycolaldehyde Formation on Interstellar Dirty Ice Mantles via a “Radical + Ice” Mechanism

ChemPlusChem, EarlyView.
The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...

Unexpected Sign Inversion of the Circular Dichroism and Circularly Polarized Luminescence Response of Chiral Copolymer Thin Films by Tuning the Thickness and Annealing Conditions

ChemPhotoChem, EarlyView.
Copolymer thin films with induced supramolecular chirality show promise for chiroptical optoelectronic applications. Sign changes of the strong circular dichroism and circularly polarized luminescence (CPL) of such films are demonstrated by tuning their film thickness and annealing conditions.

Unveiling the Damped Quantum Harmonic Oscillator

Jurnal Kumparan Fisika
This article dis cusses the often-overlooked "damped" quantum harmonic oscillator, a vibrating system that loses energy over time. We bridge the classical-quantum divide, starting with the familiar equation of motion for a damped oscillator using Hooke's

Modulation of Self‐Assembly and Enhanced Photocatalytic H2 Production by Porphyrin‐Dipeptide Conjugates

ChemSusChem, EarlyView.
Self‐assembled peptide–porphyrin conjugates are shown to produce green hydrogen under visible light irradiation. The morphology of the nanostructures, which can be tuned, directly influences catalytic activity. Among the architectures formed, tubular assemblies display the highest efficiency, offering a promising strategy for light‐driven hydrogen ...
