such as topological insulators and symmetry-protected topological phases such as topological crystalline insulators and Dirac/Weyl semimetals. Mobile impurities can be useful probes of quantum states.

Unique Weyl semimetal delivers largest intrinsic conversion of light to electricity, an international team led by Boston College researchers reports IMAGE ABOVE: The Weyl semimetal Tantalum Arsenide ...

Abstract: The development of ultrafast laser pulses is enabling unprecedented studies of the electronic dynamics of Dirac-Weyl materials subjected to intense fields. In particular, the generation of ...

From (1) and (2) one obtains the Euler equations: with the 4-current for which the equation of continuity follows from (4) and independently from (3). Nature - Dirac's New Electrodynamics Skip to ...

Abstract: Problems involving the classical linear partial differential equations of mathematical physics can be reduced to algebraic ones of a very much simpler structure by replacing the ...

It is shown that a simple continuity condition in the algebra of split octonions suffices to formulate a system of differential equations that are equivalent to the standard Dirac equations. In our ...

We develop a systematic method to derive the Majorana representation of the Dirac equation in (1+3)-dimensions. We compare with similar approach in (2+2)-dimensions. We argue that our formalism can ...
