Boundary Conditions for Current Density01:25

Boundary Conditions for Current Density

1.4K
Current density becomes discontinuous across an interface of materials with different electrical conductivities. The normal component of the current density is continuous across the boundary.

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

The Quantum-Mechanical Model of an Atom

59.8K
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

Areas Within Irregular Boundaries01:26

Areas Within Irregular Boundaries

388
Calculating areas within irregular boundaries, such as along rivers or curved roads, is crucial in various fields, including surveying, engineering, and environmental management. Surveyors often begin by creating a traverse, a connected series of straight lines approximating the area's boundary. The coordinates of each traverse point are essential for calculating the enclosed area. The double meridian distance formula is a widely used technique for this purpose. This method utilizes the...

Electron Transport Chains

113.3K
The final stage of cellular respiration is oxidative phosphorylation that consists of two steps: the electron transport chain and chemiosmosis. The electron transport chain is a set of proteins found in the inner mitochondrial membrane in eukaryotic cells. Its primary function is to establish a proton gradient that can be used during chemiosmosis to produce ATP and generate electron carriers, such as NAD+ and FAD, that are used in glycolysis and the citric acid cycle.
The ETC is comprised of...

Electrostatic Boundary Conditions

Consider an external electric field propagating through a homogeneous medium. When the electric field crosses the surface boundary of the medium, it undergoes a discontinuity. The electric field can be resolved into normal and tangential components. The amount by which the field changes at any boundary is given by the difference between the field components above and below the surface boundary.
The surface integral of an electric field is given by Gauss's law in integral form and is related to...

Area of Science:

  • Quantum mechanics
  • Statistical physics
  • Condensed matter theory

Background:

  • Open quantum systems exhibit complex dynamics due to environmental interactions.
  • Understanding the interplay between coherent transport and dissipation is crucial for quantum technologies.

Purpose of the Study:

  • To investigate the large-scale dynamics of noninteracting open quantum chains.
  • To analyze the impact of boundary dissipation, bulk dephasing, and diffusion on quantum transport.
  • To identify and characterize novel phase transitions in these systems.

Main Methods:

  • Microscopic formulation of open quantum chains (fermionic and bosonic).
  • Application of fluctuating hydrodynamics for large-scale dynamics.
  • Utilizing macroscopic fluctuation theory to compute large deviation statistics of currents.
  • Numerical simulations including the cloning method and exact diagonalization.

Main Results:

  • Large-scale dynamics are accurately described by fluctuating hydrodynamics.
  • Fermionic open chains exhibit a third-order dynamical phase transition in large deviation functions.
  • A singular change in trajectory structure occurs: typical trajectories are diffusive, while rare, atypical trajectories become ballistic and hyperuniform.
  • Numerical methods confirm the theoretical predictions for rare trajectory ensembles.

Conclusions:

  • Fluctuating hydrodynamics provides a powerful simplification for open quantum chain dynamics.
  • The discovered third-order phase transition highlights unique non-equilibrium phenomena in fermionic systems.
  • The transition from diffusive to ballistic/hyperuniform rare trajectories offers new insights into quantum transport under dissipation.
