Summary
Split-ring resonator arrays with magnetic flatbands show potential for magnetic storage. Stub and Lieb ribbons are stable against perturbations, unlike the kagome ribbon, which is unstable and has higher loss rates.
Area of Science:
- Condensed matter physics
- Electromagnetism
- Photonics
Background:
- Magnetic flatbands in split-ring resonator arrays are crucial for novel electronic and photonic applications.
- Understanding the stability of these flatbands under perturbations is essential for device realization.
Purpose of the Study:
- To investigate the spectrum and localization properties of stub, Lieb, and kagome lattice arrays with magnetic flatbands.
- To analyze the impact of perturbations on magnetic flatband stability and spectral characteristics.
- To assess the effect of losses on flatband properties and identify potential applications.
Main Methods:
- Analytical and numerical studies of quasi-one-dimensional split-ring resonator arrays.
- Perturbation analysis to assess stability against geometrical interference disruptions.
- Incorporation of losses to evaluate flatband behavior under dissipative conditions.
Main Results:
- Stub and Lieb ribbon arrays exhibit stable magnetic flatbands against considered perturbations.
- Kagome ribbon arrays are generally unstable, with higher loss rates when dissipation is included.
- All studied flatbands remain dispersionless but become complex in the presence of losses.
Conclusions:
- The stability of flatband modes in stub and Lieb resonator arrays suggests their suitability for future magnetic storage devices.
- The kagome ribbon's instability highlights the sensitivity of its flatband properties to perturbations and losses.
- Further research into stable flatband systems could pave the way for advanced magnetic data storage technologies.

01:30Oscillations In An LC Circuit
3.2K
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

01:17Spin–Spin Coupling: One-Bond Coupling
1.5K
Coupling interactions are strongest between NMR-active nuclei bonded to each other, where spin information can be transmitted directly through the pair of bonding electrons. While nuclei polarize their electrons to the opposite spins, the bonding electron pair has opposite spins. Configurations with antiparallel nuclear spins are expected to be lower in energy. When coupling makes antiparallel states more favorable, J is considered to have a positive value. The one-bond coupling constant, 1J,...

A stationary charge creates and interacts with the electric field, while a moving charge creates a magnetic field.
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...

1.5K
In bromoethane, the three methyl protons are coupled to the two methylene protons that are three bonds away. In accordance with the n+1 rule, the signal from the methyl protons is split into three peaks with 1:2:1 relative intensities. The methylene protons appear as a quartet, with the relative intensities of 1:3:3:1.

01:23Atomic Nuclei: Nuclear Relaxation Processes
1.3K
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.

1.7K
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...
