The de Broglie Wavelength02:32

The de Broglie Wavelength

30.6K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Atomic Nuclei: Types of Nuclear Relaxation

454
Nuclear relaxation restores the equilibrium population imbalance and can occur via spin–lattice or spin–spin mechanisms, which are first-order exponential decay processes.
In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers...

Deactivation Processes: Jablonski Diagram

1.1K
Luminescence, the emission of light by a substance that has absorbed energy, is a process that involves the interaction of molecules with light. The energy-level diagram, or Jablonski diagram, is a graphical representation of these interactions, illustrating the various states and transitions a molecule can undergo. In a typical Jablonski diagram, the lowest horizontal line represents the ground-state energy of the molecule, which is usually a singlet state. This state represents the energies...

Chronopharmacokinetics: Time-Dependent Pharmacokinetics

242
Chronopharmacokinetics studies the temporal change in drug absorption and elimination. These changes can be cyclical or non-cyclical. Cyclical changes occur over a regular interval, while non-cyclical changes occur over a longer, irregular period.
Time-dependent pharmacokinetics refers to non-cyclical changes in drug rate processes over a period of time. It can lead to nonlinear pharmacokinetics, where the relationship between drug concentration and time is not proportional. Non-cyclical...

Double Resonance Techniques: Overview01:12

Double Resonance Techniques: Overview

359
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

Directionality of Nuclear Transport01:42

Directionality of Nuclear Transport

3.7K
Ras-related nuclear protein or Ran is a small G protein that cycles between its GTP and GDP bound states. Ran specific regulators, a Ran GTPase Activating Protein or RanGAP present in the cytosol and a Ran guanine nucleotide exchange factor or RanGEF present inside the nucleus regulate GTP/GDP exchange. A high concentration of GTP inside the cells, in addition to this asymmetric distribution of  Ran-specific regulators, leads to a higher RanGTP concentration inside the nucleus. This...

Summary
This summary is machine-generated.

Dephasing-assisted quantum transport can occur in non-Markovian scenarios. Its manifestation depends on how energy sources couple to the system, specifically appearing in non-symmetric configurations for enhanced quantum transport.

  • Condensed matter physics

Background:

  • Dephasing-assisted quantum transport typically studied in Markovian (constant rate) scenarios.

  • Examination of different configurations for local energy source coupling (non-symmetric and symmetric).

Main Results:

  • Non-Markovian dephasing-assisted transport is configuration-dependent.
  • Manifestation of non-Markovian dephasing-assisted transport observed exclusively in the non-symmetric coupling configuration.
  • Findings parallel conditions for Markovian dephasing-assisted transport.

Conclusions:

  • Non-Markovian dephasing can facilitate quantum transport under specific coupling conditions.
  • The symmetry of energy source coupling is crucial for non-Markovian dephasing-assisted transport.
