2015-02-13 | Magnetohydrodynamic kink waves in nonuniform solar flux tubes: phase mixing and energy cascade to small scales | Magnetohydrodynamic (MHD) kink waves are ubiquitously observed in the solar
atmosphere. The propagation and damping of these waves may play relevant roles
for the transport and dissipation of energy in the solar atmospheric medium.

2016-09-30 | Modelling observed decay-less oscillations as resonantly enhanced Kelvin-Helmholtz vortices from transverse MHD waves and their seismological application | In the highly structured solar corona, resonant absorption is an unavoidable
mechanism of energy transfer from global transverse MHD waves to local
azimuthal Alfv\'en waves. Due to its localised nature, a direct detection of
this mechanism is extremely difficult. Yet, it is the leading theory explaining
the observed fa... | 1609.09716v1 |
2017-05-25 | Elastic wave control beyond band-gaps: shaping the flow of waves in plates and half-spaces | It is well known in metamaterials that local resonance and hybridization
phenomena dramatically influence the shape of dispersion curves; the
metasurface created by a cluster of resonators, subwavelength rods, atop an
elastic surface being an exemplar with these features. On this metasurface,

2016-12-15 | Tidal dissipation by inertial waves in differentially rotating convective envelopes of low-mass stars | Tidal interactions in close star-planet or binary star systems may excite
inertial waves (their restoring force is the Coriolis force) in the convective
region of the stars. The dissipation of these waves plays a prominent role in
the long-term orbital and rotational evolution of the bodies involved. If the

structures, referred to as time domain structures (TDSs), often occur around
dipolarization fronts in the Earth's inner magnetosphere. They are considered
to be important because of their role in the dissipation of the injection

2022-01-31 | How a realistic magnetosphere alters the polarizations of surface, fast magnetosonic, and Alfvén waves | System-scale magnetohydrodynamic (MHD) waves within Earth's magnetosphere are

in the absence of SDW pinning the phason is completely absorbed by the plasmon

1998-07-22 | Theory of Coexisting Charge and Spin-Density Waves in (TMTTF)_2Br, (TMTSF)_2PF_6 and alpha-(BEDT-TTF)_2MHg(SCN)_4 | Recent experiments indicate that the spin-density waves (SDWs) in
(TMTTF)_2Br, (TMTSF)_2PF_6 and alpha-(BEDT-TTF)_2MHg(SCN)_4 are highly
unconventional and coexist with charge-density waves (CDWs). We present a

is odd in frequency, so that the order parameter vanishes at zero frequency and
there is a conventional Fermi surface. Such states break translational symmetry
and, therefore, are not conventional Fermi liquids. In the odd-frequency

(SDW) in p-wave, d-wave and f-wave superconductors. To describe the low-energy
quasiparticle excitation of p-wave case, we introduce a two- (one for time and
one for space) dimensional massless Dirac model. After the non-Abelian

fermionic atoms with attractive three-dimensional p-wave interactions in a
hard-wall trap. This is possible since the one-dimensional fermion system can

2009-07-07 | Multiband Superconductivity in Spin Density Wave Metals | We study the emergence of multiband superconductivity with $s$- and $d-$wave
symmetry on the background of spin density wave (SDW). We show that the SDW

long-range order even when all symmetries are preserved in the wave function.
This fact is mainly related to the presence of a sufficiently strong Jastrow
