Moreover the Dirac Speaker Sound, the slim design and large Full HD+ display of 6.2' provides users an immersive display that truly upgrades the entertainment experience.
After a general introduction to topological semi-metals, he examines the phenomenon in such specimens as Dirac semi-metals, Weyl semi-metals, antimony and antimonides, bismuthides, carbon and carbides, metals and alloys, oxides, and phosphorus and phosphides.
HOT 7,an upgraded smartphone designed specifically for optimized performance, has set entertainment as the brand tone for the HOT series, boasting a 6.2' largescreen, a large battery with a power of 4000 mAh and Dirac mode speakers.
He published his research on the "Extended Dirac Equation for Elementary Fermions based on Applying 8-Dimensional Spinors." DOI: 10.13140/RG.2.2.23994.90569
[1-5], the Dirac 4 x 4 [gamma]-matrices ([[gamma].sup.[mu]]) are usually presented as objects that undergo a transformation during a Lorentz transformation of the Dirac [6.7] equation.
Also, there are a lot of investigations that show how methods used to obtain analytical solutions of the Schroodinger equation can be extended to Dirac case [11-15].
Concerning fermion fields, and in particular Dirac spinors, a consistent framework to deal with the corresponding quantum field theory in a cosmological context was put forward several years ago by D'Eath and Halliwell [2] (see also [3] for a more general discussion).
It is also worth noting that there is no significant shift in the Dirac point which is the minimum conductance point in the device transfer curve, which indicates that the n- or p-type property of the graphene does not change with IgE [22].
For example, it was recently realised that isolated touching points of these bands can be stabilised by certain crystalline symmetries, creating so-called Dirac fermions in the bulk electronic structure.
In 1926, Breit (2) discussed this problem using the correspondence principle in the old quantum theory, and obtained the same result as what Dirac (3) and subsequently Gordon (4) obtained independently, using quantum mechanics.
Investing further in the build-out of its senior management team, Dirac Research appointed Lars Isaksson business director of AR/VR.
