[1802.04673] Magnetic

2018/2/13When very high magnetic fields suppress the superconductivity in underdoped cuprates, an exceptional new electronic phase appears. It supports remarkable and unexplained quantum oscillations and exhibits an unidentified density wave (DW) state. Although generally referred to as a charge density wave (CDW) because of the observed charge density modulations, theory indicates that this

Electromagnetic radiation

A linearly polarized sinusoidal electromagnetic wave, propagating in the direction +z through a homogeneous, isotropic, dissipationless medium, such as vacuum. The electric field (blue arrows) oscillates in the x-direction, and the orthogonal magnetic field (red arrows) oscillates in phase with the electric field, but in the y-direction.

Field induced spin density waves in a tilted magnetic

1989/3/21In general the field induced spin density wave (FISDW) state is characterized by a set of intergers (n,m), though in the high field region (H 5T) the FISDW is dominated by the state with m = 0. We find a dip in T c ( H, φ ) at φ = φ c = tan −1 ( b / c )≅30 for the even n state, which should be readily observable experimentally.

Effect of High Magnetic Fields on the

We present a systematic study on a large magnetoresistance in NbSe 3 as a function of temperature under various pressures. The large magnetoresistance below T c2 is observed as long as the T c2-CDW phase exists.However, when the T c2-CDW phase is suppressed totally by high pressure and the superconducting phase is induced at the same time, no anomaly, including the large

Orbital quantization in the high magnetic field state of a charge

A superposition of the Pauli and orbital coupling of a high magnetic field to charge carriers in a charge-density-wave (CDW) system is proposed to give rise to transitions between subphases with quantized values of the CDW wavevector. By contrast to the pu

Graphite is a semimetal that consists of carbon atoms, and is known to undergo magnetic-field-induced phase transitions at low temperatures and high magnetic fields along the c-axis. These transitions are observed as abrupt resistance changes, and are interpreted as the occurrence of a spin- or charge- density wave along the c-axis. Besides, it has been well believed that the density wave

Magnetic field–induced pair density wave state in the

2019/6/7Magnetic fields can cause the formation of vortices in a superconductor. In cuprate superconductors, the vortex cores are surrounded by "halos," where the density of electronic states exhibits a checkerboard pattern. Edkins et al. used scanning tunneling spectroscopy to take a closer look into the halos. The results revealed that the patterns correspond to an exotic state called the pair

Magnetic field

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents,: ch1 and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.: ch13 A permanent magnet′s magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets.

The main panel shows the folded dispersion in the presence of a CDW, which gaps out part of the Landau levels, with the lower branch ( b ) shifted by Q C D W .

Chiral singlet superconductivity in the weakly correlated

Chiral superconductors are novel topological materials with finite angular momentum Cooper pairs circulating around a unique chiral axis, thereby spontaneously breaking time-reversal symmetry. They are rather scarce and usually feature triplet pairing: a canonical example is the chiral p-wave state realized in the A-phase of superfluid He3. Chiral triplet superconductors are, however

2009/8/1Whilst the realization of graphene, probably one of the best two-dimensional carrier systems to study, has attracted much research interest recently, graphite, which may be regarded as multi-layered graphene, has also been known to exhibit very interesting phenomena at high magnetic fields and low temperatures. The electron-hole system in the compensated semimetal graphite undergoes a magnetic

Although routinely labeled a charge density wave (CDW), this DW state could actually be an electron-pair density wave (PDW). To search for evidence of a field-induced PDW, we visualized modulations in the density of electronic states N(r) within the halo surrounding Bi2Sr2CaCu2O8 vortex cores.

Moreover, we study, within a mean field theory, the effect of the anion gap on the field induced spin density wave (FISDW) phases at high magnetic field. By analyzing the behavior of these phases, we conclude that the anion gap has to be small compared to the interchain hopping parameter.
