Magneto-Optical Faraday Effect in Quasicrystalline and Aperiodic Microresonator Structures

Magnetochemistry, 2023
We theoretically and numerically investigate magnetophotonic microresonators formed by a magnetic layer sandwiched between two reflective multilayers with different layer arrangements.

Projected topological branes

Communications Physics, 2022
Authors introduce a new class of topological materials, namely projected topological branes that are holographic images of higher-dimensional topological crystals, and feature either emergent crystalline or aperiodic quasicrystalline order. They manifest

Age-Related Differences and Effects of Internalizing Symptoms on Aperiodic Neural Activity in Adolescents. [PDF]

Psychophysiology
ABSTRACT The power spectrum derived from electroencephalography (EEG) recordings has been shown to include both periodic (e.g., delta, theta, alpha, beta) and aperiodic (e.g., 1/f exponent shape, vertical offset) components. Although internalizing disorders have been characterized by alterations in several periodic EEG measures, aperiodic activity has ...

Fractional Transport of Photons in Deterministic Aperiodic Structures

Scientific Reports, 2017
The propagation of optical pulses through primary types of deterministic aperiodic structures is numerically studied in time domain using the rigorous transfer matrix method in combination with analytical fractional transport models.

EEG Fingerprints under Naturalistic Viewing Using a Portable Device

Sensors, 2020
The electroencephalogram (EEG) has been proven to be a promising technique for personal identification and verification. Recently, the aperiodic component of the power spectrum was shown to outperform other commonly used EEG features.

Task-related, intrinsic oscillatory and aperiodic neural activity predict performance in naturalistic team-based training scenarios

Scientific Reports, 2022
Effective teams are essential for optimally functioning societies. However, little is known regarding the neural basis of two or more individuals engaging cooperatively in real-world tasks, such as in operational training environments.

Rapid adaptation of predictive models during language comprehension: Aperiodic EEG slope, individual alpha frequency and idea density modulate individual differences in real-time model updating

Frontiers in Psychology, 2022
Predictive coding provides a compelling, unified theory of neural information processing, including for language. However, there is insufficient understanding of how predictive models adapt to changing contextual and environmental demands and the extent ...

Second-Order Phase Transition Induced by Deterministic Fluctuations in Aperiodic Eight-State Potts Models

, 1998
We investigate the influence of aperiodic modulations of the exchange interactions between nearest-neighbour rows on the phase transition of the two-dimensional eight-state Potts model.

From the Fibonacci Icosagrid to E₈ (Part I): The Fibonacci Icosagrid, an H₃ Quasicrystal

Crystals
This paper introduces a new kind of quasicrystal by Fibonacci-spacing a multigrid of a certain symmetry, like H2, H3, T3, etc. Multigrids of a certain symmetry can be used to generate quasicrystals, but multigrid vertices are not a quasicrystal due to ...

Event-Triggered Dissipative Filtering for Network-Based Stochastic Genetic Regulatory Networks Under Aperiodic Sampling

IEEE Access, 2020
Based on event-triggered mechanism, networked dissipative filtering of stochastic genetic regulatory networks is investigated under aperiodic sampling.
