Perturbation approach for nuclear magnetic resonance solid‐state quantum computation [PDF]

Journal of Applied Mathematics, 2003
A dynamics of a nuclear‐spin quantum computer with a large number (L = 1000) of qubits is considered using a perturbation approach. Small parameters are introduced and used to compute the error in an implementation of an entanglement between remote qubits, using a sequence of radio‐frequency pulses.

Magnetohydrodynamic kink waves in two-dimensional non-uniform prominence threads [PDF]

, 2011
We analyse the oscillatory properties of resonantly damped transverse kink oscillations in two-dimensional prominence threads. The fine structures are modelled as cylindrically symmetric magnetic flux tubes with a dense central part with prominence ...

Linear and nonlinear resonant interaction of sound waves in dissipative layers [PDF]

, 2000
The theory of resonant nonlinear magnetohydrodynamic (MHD) waves in dissipative steady plasmas developed by Ballai and Erdélyi is used to study the effect of steady flows on nonlinear resonant heating of MHD waves in (a) linear, (b) weakly and (c ...

Damping mechanisms for oscillations in solar prominences [PDF]

, 2010
Small amplitude oscillations are a commonly observed feature in prominences/filaments. These oscillations appear to be of local nature, are associated to the fine structure of prominence plasmas, and simultaneous flows and counterflows are also present ...

Effect of resonant magnetic perturbations including toroidal sidebands on magnetic footprints and fast ion losses in HL-2M

Nuclear Fusion, 2023
Externally applied resonant magnetic perturbations (RMPs), generated by magnetic coils located outside the plasma (referred to as RMP coils), provide an effective way to control the edge localized mode (ELM) in tokamak devices. Due to the discrete nature

ELM mitigation via rotating resonant magnetic perturbations on MAST [PDF]

Journal of Nuclear Materials, 2015
The application of resonant magnetic perturbations (RMPs) produces splitting of the divertor strike point due to the interaction of the RMP field and the plasma field. The application of a rotating RMP field causes the strike point splitting to rotate, distributing the particle and heat flux evenly over the divertor.

Effect of aspect ratio on plasma response to resonant magnetic perturbations in tokamak devices

AIP Advances, 2023
A systematic numerical study is carried out, computing and comparing the plasma response to the resonant magnetic perturbation (RMP) field, applied for controlling edge localized modes (ELMs), in a series of tokamak plasmas with varying aspect ratio and ...

Pressure-driven amplification and penetration of resonant magnetic perturbations [PDF]

Physics of Plasmas, 2016
We show that a resonant magnetic perturbation applied to the boundary of an ideal plasma screw-pinch equilibrium with nested surfaces can penetrate inside the resonant surface and into the core. The response is significantly amplified with increasing plasma pressure.
