Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)01:20

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)

Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Area of Science:

  • Physics
  • Network Science
  • Nonlinear Dynamics

Background:

  • Laser networks exhibit complex dynamics.
  • Synchronization in coupled systems is crucial for various applications.
  • Time delays significantly impact network behavior.

Purpose of the Study:

  • To experimentally investigate phase dynamics in laser networks with time-delayed mutual coupling.
  • To establish fundamental rules governing network synchronization.
  • To understand the role of substructures in network synchronization.

Main Methods:

  • Experimental setup involving laser networks.
  • Homogeneous time-delayed mutual coupling.
  • Analysis of phase dynamics and synchronization states.

Main Results:

  • Identified a specific substructure that imposes its synchronization state on the entire network.
  • Demonstrated that networks form at most two synchronized clusters, irrespective of coupling configuration.
  • Synchronization is a nonlocal phenomenon, not deducible from smaller substructures.

Conclusions:

  • The synchronization state of a laser network is a global property.
  • Substructures play a critical role in dictating overall network synchronization.
  • Understanding nonlocal effects is key to predicting and controlling network synchronization.
