Condensed matter realization of the axial magnetic effect

Model for a quantum Hall effect without Landau levels: Condensed-matter realization of the "parity anomaly"

The quantum Hall effect' (QHE) in two-dimensional (2D) electron systems is usually associated with the presence of a uniform externally generated magnetic field, which splits the spectrum of electron energy levels into Landau levels. In this Letter I show how, in principle, a QHE may also result from breaking of time-reversal symmetry (i.e., magnetic ordering) without any net magnetic fiux thro...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Condensed matter

Foreword Physics and physicists play a vital role in underpinning our way of life, improving its quality and contributing in a major way to wealth creation. Innovations as powerful and diverse as the World Wide Web and magnetic resonance imaging (MRI) have emerged from studies in basic physics, becoming everyday technologies in just two decades. It is, therefore, a worthwhile challenge to specu...
