Our previous " exotic " particle, together with the more recent anomalous anyon model (which has arbitrary gyromagnetic factor g) are reviewed. The non-relativistic limit of the anyon generalizes the exotic particle which has g = 0 to any g. When put into planar electric and magnetic fields, the Hall effect becomes mandatory for all g = 2, when the field takes some critical value.

The quantum Hall conductance of a disordered two-dimensional gas of non-interacting electrons is reexamined for its integrity against disorder in the limit of no mixing between different Landau levels. The exact one-electron eigenstates of the disordered system are shown to be current carrying, with exactly the same Hall current as in the absence of disorder. There are no localized states. Acco...

This paper presents a distance detector composed of two separated metal-oxide semiconductor field-effect transistors (MOSFETs), a differential polysilicon cross-shaped Hall plate (CSHP), and a readout circuit. The distance detector was fabricated using 0.18 μm 1P6M Complementary Metal-Oxide Semiconductor (CMOS) technology to sense the magnetic induction perpendicular to the chip surface. The di...

We have analyzedthe motion of a Hallprobe,which is rotatedabout an axis that is arbitrarily displacedand oriented with respect to the magnetic axis of a solenoid. We outline how the magnetic field measured by the rotating Hall probe can be calculated. We show how to compare theoretical results with actual measurements, to determine the displacementand orientation of the axis of rotation of the ...

— This paper reviews recent developments in the theory of the quantum Hall effect (QHE) in the magnetic-field-induced spin-density-wave (FISDW) state of the quasi-one-dimensional organic conductors (TMTSF)2X. The origin and the basic features of the FISDW are reviewed. The QHE in the pinned FISDW state is derived in several simple, transparent ways, including the edge states formulation of the ...

the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...

This paper introduces a new concept for the magnetic field in a Hall-effect thruster. The Magnetic Interference Hall Accelerator (MIHA) uses independent magnetic circuit elements to put its peak magnetic field outside its exit plane. As a result, the zone of minimum electron mobility is outside its exit plane, as well as its ion acceleration zone. Wall-effects are reduced, and ion bombardment o...

We present a theory of the thermal Hall effect in insulating quantum magnets, where the heat current is totally carried by charge-neutral objects such as magnons and spinons. Two distinct types of thermal Hall responses are identified. For ordered magnets, the intrinsic thermal Hall effect for magnons arises when certain conditions are satisfied for the lattice geometry and the underlying magne...

The effect of a tunable, externally coupled Fabry-Perot cavity to resonantly enhance the optical Hall effect signatures at terahertz frequencies produced by a traditional Drude-like two-dimensional electron gas is shown and discussed in this Letter. As a result, the detection of optical Hall effect signatures at conveniently obtainable magnetic fields, for example, by neodymium permanent magnet...
