Atomic Nuclei: Nuclear Spin State Overview

1.0K
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of...

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 arrangement of electrons in the orbitals of an atom is called its electron configuration. We describe an electron configuration with a symbol that contains three pieces of information:

Atomic Nuclei: Nuclear Spin

2.2K
All atomic particles possess an intrinsic angular momentum, or 'spin'. Electrons, protons, and neutrons each have a spin value of ½, although protons and neutrons in nuclei may have higher half-integer spins owing to energetic factors.
Atomic nuclei have a net nuclear spin, , which can have an integer or half-integer value. In atomic nuclei, the spins of protons are paired against each other but not with neutrons, and vice versa. Consequently, an even number of protons does not...

Atomic Nuclei: Nuclear Spin State Population Distribution01:14

Atomic Nuclei: Nuclear Spin State Population Distribution

1.1K
Near absolute zero temperatures, in the presence of a magnetic field, the majority of nuclei prefer the lower energy spin-up state to the higher energy spin-down state. As temperatures increase, the energy from thermal collisions distributes the spins more equally between the two states. The Boltzmann distribution equation gives the ratio of the number of spins predicted in the spin −½ (N−) and spin +½ (N+) states.

Atomic Nuclei: Nuclear Magnetic Moment00:59

Atomic Nuclei: Nuclear Magnetic Moment

1.3K
All atomic nuclei are positively charged. When they have a nonzero spin, they behave like rotating charges. As a consequence of their charge and spin, these nuclei generate a magnetic field (B). This, in turn, gives rise to a magnetic moment (μ), which is randomly oriented in the absence of an external magnetic field. When an external magnetic field (B0) is applied, the magnetic moment vectors can align with the field or against it in 2 + 1 orientations. A hydrogen nucleus, which is just a...

Area of Science:

  • Condensed Matter Physics
  • Quantum Magnetism

Background:

  • The J1-J2 model is a fundamental model for studying magnetic interactions in materials.
  • Understanding exotic magnetic phases like the spin-nematic state is crucial for novel electronic properties.

Purpose of the Study:

  • To provide strong evidence for the spin-nematic state in the ferro-antiferromagnetic J1-J2 model.
  • To elucidate the conditions stabilizing the nematic phase and the impact of many-body effects.

Main Methods:

  • Analytical techniques.
  • Density-matrix renormalization group (DMRG) methods.

Main Results:

  • The spin-nematic state is stabilized by pair repulsion in a narrow region near the pair-condensation field.
  • A first-order transition occurs in zero field due to spin-flip pair attraction, preventing a nematic state.
  • Many-body effects suppress the spin-flip gap, significantly reducing the nematic phase's extent.

Conclusions:

  • The findings offer a detailed understanding of the spin-nematic state's emergence and behavior.
  • The proposed phase diagram is expected to be broadly applicable to similar magnetic systems.
