Electric Field of Two Equal and Opposite Charges01:30

Electric Field of Two Equal and Opposite Charges

6.9K
Atoms generally contain the same number of positively and negatively charged particles, protons, and electrons. Hence, they are electrically neutral. However, the centers of the positive and negative charges do not always coincide. In such a scenario, the electric field of an atom may not be zero.
A separation of the positive and negative charges can lead to a weak, remnant effect of the positive and negative charges. The expectation is that the more the distance between the positive and...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Induced Electric Dipoles

4.7K
A permanent electric dipole orients itself along an external electric field. This rotation can be quantified by defining the potential energy because the external torque does work in rotating it. Then, the potential energy is minimum at the parallel configuration and maximum at the antiparallel configuration. While the former is a stable equilibrium, the latter is an unstable equilibrium.
Since the absolute value of potential energy holds no physical meaning, its zero value can be chosen as per...

The Quantum-Mechanical Model of an Atom

56.4K
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.

Electric Field at the Surface of a Conductor01:26

Electric Field at the Surface of a Conductor

5.2K
Consider a conductor in electrostatic equilibrium. The net electric field inside a conductor vanishes, and extra charges on the conductor reside on its outer surface, regardless of where they originate.
In the 19th century, Michael Faraday conducted the famous ice pail experiment to prove that the charges always reside on the surface of a conductor. The experimental set-up consists of a conducting uncharged container mounted on an insulating stand. The outer surface of the container is...

Electric Dipoles and Dipole Moment01:30

Electric Dipoles and Dipole Moment

6.2K
Consider two charges of equal magnitude but opposite signs. If they cannot be separated by an external electric field, the system is called a permanent dipole. For example, the water molecule is a dipole, making it a good solvent.
Theoretically, studying electric dipoles leads to understanding why the resultant electric forces around us are weak. Since electric forces are strong, remnant net charges are rare. Hence, the interaction between dipoles helps us understand electrical interactions in...

Area of Science:

  • Molecular Quantum Information Science
  • Spin Physics and Chemistry
  • Quantum Computing and Information

Background:

  • Spin-electric coupling in molecules with hyperfine-coupled spins is key for electric field-based molecular quantum information.
  • Previous work addressed electronic degrees of freedom in [Tm{N(SiⁱPr₃)₂}₂].
  • Hyperfine coupling breaks Kramers degeneracy, enabling zeroth-order spin-electric coupling.

Purpose of the Study:

  • To investigate electric field control of nuclear spins by explicitly treating both electronic and nuclear spins (I=1/2).
  • To determine how nuclear spin inclusion influences overall spin-electric coupling.
  • To explore the potential for coherent manipulation of molecular spins using electric fields.

Main Methods:

  • Theoretical treatment of both electronic and nuclear spins.
  • Classification of transitions based on EPR, NMR, or mixed/forbidden character.
  • Dissipative spin-dynamics simulations.

Main Results:

  • EPR-like transitions exhibit stronger coupling to electric fields than NMR-like transitions, due to dominant crystal-field modulation over hyperfine modulation.
  • Zeroth-order spin-electric coupling suppresses magnetic-field orientation dependence, consistent with previous findings on anisotropy.
  • Simulations indicate that feasible electric field strengths and relaxation times allow coherent manipulation of both electronic and nuclear spins.

Conclusions:

  • Explicit inclusion of nuclear spins confirms the possibility of electric field control over nuclear degrees of freedom.
  • The study demonstrates a viable experimental pathway for electric field control of quantum information in [Tm{N(SiⁱPr₃)₂}₂].
  • Findings pave the way for developing advanced molecular quantum technologies utilizing spin-electric coupling.
