A Classification of Lie Algebras of Pseudo-Unitary Groups in the Techniques of Clifford Algebras [PDF]

open access: greenAdvances in Applied Clifford Algebras, 2009
In this paper we present new formulas, which represent commutators and anticommutators of Clifford algebra elements as sums of elements of different ranks. Using these formulas we consider subalgebras of Lie algebras of pseudounitary groups. Our main techniques are Clifford algebras. We have find 12 types of subalgebras of Lie algebras of pseudounitary

Classification of Extended Clifford Algebras [PDF]

open access: greenRussian Mathematics, 2018
Considering tensor products of special commutative algebras and general real Clifford algebras, we arrive at extended Clifford algebras. We have found that there are five types of extended Clifford algebras. The class of extended Clifford algebras is closed with respect to the tensor product.

Classification of 7-dimensional subalgebras of 8-dimensional Clifford algebra [PDF]

open access: green, 2018
All 7-dimensional subalgebras of the 8-dimensional Clifford algebra over the field C of complex numbers are found. Canonical bases are used throughout the determination. It is found that the 8-dimensional Clifford algebra over C has exactly eight 7-dimensional subalgebras and each of these eight is over the complex numbers.

Hyperquaternions and physics

open access: yesSciPost Physics Proceedings, 2023
The paper develops, within a new representation of Clifford algebras in terms of tensor products of quaternions called hyperquaternions, several applications.

Fault-Tolerant Logical Gates in Holographic Stabilizer Codes Are Severely Restricted

open access: yesPRX Quantum, 2021
We evaluate the usefulness of holographic stabilizer codes for fault-tolerant quantum computing by studying their allowed sets of fault-tolerantly implementable gates.

BPS black hole entropy and attractors in very special geometry. Cubic forms, gradient maps and their inversion

open access: yesJournal of High Energy Physics, 2021
We consider Bekenstein-Hawking entropy and attractors in extremal BPS black holes of N $$ \mathcal{N} $$ = 2, D = 4 ungauged supergravity obtained as reduction of minimal, matter-coupled D = 5 supergravity.

Subliminal aspects concerning the Lounesto’s classification

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
In the present communication we employ a split programme applied to spinors belonging to the regular and singular sectors of the Lounesto’s classification (Clifford algebras and spinors, Cambridge University Press, Cambridge), looking towards unveil how ...
