Summary
This study proposes a new method for measuring atomic spin weak values using a modified Stern-Gerlach apparatus. Simulations show this technique is feasible for detecting beam displacements in metastable helium atoms.
Area of Science:
- Atomic Physics
- Quantum Measurement
Background:
- Measuring weak values in quantum mechanics is challenging.
- The Stern-Gerlach apparatus is a foundational tool in atomic physics.
Purpose of the Study:
- To propose and simulate a feasible method for measuring the weak value of atomic spin.
- To identify experimental parameters for accurate weak value determination.
Main Methods:
- Utilized a variant of the Stern-Gerlach apparatus.
- Performed a full simulation of the experiment using the impulsive approximation.
- Analyzed beam displacement of metastable helium atoms.
Main Results:
- Predicted beam displacement (Δw) for helium atoms is within the resolution of microchannel plate detectors.
- The proposed method is demonstrated as experimentally feasible.
- Identified key experimental parameters for accurate weak value measurement.
Conclusions:
- The modified Stern-Gerlach apparatus offers a viable approach for measuring atomic spin weak values.
- The study provides a roadmap for future experimental investigations in quantum measurement.

1.5K
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 one, the...

01:14Atomic Nuclei: Nuclear Spin State Population Distribution
1.6K
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.

In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis, the precessing magnetic moments are randomly oriented around the z-axis.

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 contribute to...

1.3K
Spin systems where the difference in chemical shifts of the coupled nuclei is greater than ten times J are called first-order spin systems. These nuclei are weakly coupled, and their chemical shifts and coupling constant can generally be estimated from the well-separated signals in the spectrum.
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

The number of nuclear spins aligned in the lower energy state is slightly greater than those in the higher energy state. In the presence of an external magnetic field, as the spins precess at the Larmor frequency, the excess population results in a net magnetization oriented along the z axis. When a pulse or a short burst of radio waves at the Larmor frequency is applied along the x axis, the coupling of frequencies causes resonance and flips the nuclear spins of the excess population from the...
