Quantum oscillations in interaction-driven insulators

SciPost Physics, 2022
In recent years it has become understood that quantum oscillations of the magnetization as a function of magnetic field, long recognized as phenomena intrinsic to metals, can also manifest in insulating systems.

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]

, 2012
We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

Electromagnetic properties of neutrinos: three new phenomena in neutrino spin oscillations

EPJ Web of Conferences, 2016
In studies of neutrino electromagnetic properties we discuss three very inter-esting aspects related to neutrino spin oscillations. First we consider neutrino mixing and oscillations in the mass and flavour bases under the influence of a constant ...

An Adaptive Additional Control Strategy for Suppressing Low-Frequency Grid Oscillations in Doubly-Fed Wind Farms

Shanghai Jiaotong Daxue xuebao, 2023
Aiming at the problem of weakly or negatively damped low-frequency oscillations caused by cross-zone transmission of electricity from large wind farms, this paper proposes a fast terminal sliding-mode additional damping controller based on the Lyapunov ...

Tinnitus intensity dependent gamma oscillations of the contralateral auditory cortex. [PDF]

, 2009
Non-pulsatile tinnitus is considered a subjective auditory phantom phenomenon present in 10 to 15% of the population. Tinnitus as a phantom phenomenon is related to hyperactivity and reorganization of the auditory cortex.

Electronic subbands in the a-LaAlO_{3}/KTaO_{3} interface revealed by quantum oscillations in high magnetic fields

Physical Review Research, 2021
Investigating Shubnikov-de Haas (SdH) oscillations in high magnetic fields, we experimentally infer the electronic band structure of the quasi-two-dimensional electron gas (2DEG) at the ionic-liquid gated amorphous (a)-LaAlO_{3}/KTaO_{3} interface.

Causal evidence that intrinsic beta frequency is relevant for enhanced signal propagation in the motor system as shown through rhythmic TMS [PDF]

, 2016
Correlative evidence provides support for the idea that brain oscillations underpin neural computations. Recent work using rhythmic stimulation techniques in humans provide causal evidence but the interactions of these external signals with intrinsic ...

Zeeman Splitting of Torsional Oscillation Frequencies of Magnetars

Universe, 2023
Magnetars form a special class of neutron stars possessing superstrong magnetic fields and demonstrating power flares triggered by these fields. Observations of such flares reveal the presence of quasi-periodic oscillations (QPOs) at certain frequencies;

Magnetic oscillations induced by phonons in non-magnetic materials [PDF]

Communications Physics, 2020
AbstractAn unexpected finding two decades ago demonstrated that Shockley electron states in noble metal surfaces are spin-polarized, forming a circulating spin texture in reciprocal space. The fundamental role played by the spin degree of freedom was then revealed, even for a non-magnetic system, whenever the spin-orbit coupling was present with some ...

Oscillations of the Magnetic Network [PDF]

International Astronomical Union Colloquium, 1993
AbstractWe present high-quality power spectra of oscillations in the quiet solar chromosphere measured from the Ca II H line. They show unambiguously that the network does not participate in chromospheric three-minute oscillations, but that instead it oscillates in slow wave motions which are neither present in the surrounding non-magnetic chromosphere,
