Alternative mathematical explorations in quantum computing can be of great scientific interest, especially if they come with penetrating physical insights. In this paper, we present a critical revisitation of our application of geometric (Clifford) algebras (GAs) in quantum computing as originally presented in [C. Cafaro and S. Mancini, Adv. Appl. Clifford Algebras 21, 493 (2011)]. Our focus is on testing the usefulness of geometric algebras (GAs) techniques in two quantum computing applications. First, making use of the geometric algebra of a relativistic configuration space (namely multiparticle spacetime algebra or MSTA), we offer an explicit algebraic characterization of one- and two-qubit quantum states together with a MSTA description of one- and two-qubit quantum computational gates. In this first application, we devote special attention to the concept of entanglement, focusing on entangled quantum states and two-qubit entangling quantum gates.

Special Issue open for submission!
Title: Symmetry and Asymmetry in Nondestructive Testing
Editor: Dr. Gaofeng Sha and Prof. Dr. Yang Li
Details: https://www.mdpi.com/si/251610

Symmetry and asymmetry are ubiquitous phenomena in nondestructive testing (NDT). The following are examples: a metal test object may have a certain crystalline symmetry; a composite test object may have a symmetric/asymmetric layup; the ultrasonic testing method may use symmetric/asymmetric wave modes in physics; and the electromagnetic testing may use symmetric/asymmetric coil arrangements. There are too many examples of symmetry and asymmetry in nondestructive testing to name all of them. Therefore, this abundance would inspire new research in NDT from the perspective of symmetry and asymmetry. We are pleased to invite you to submit your manuscripts about symmetry/asymmetry phenomena in nondestructive testing to this Special Issue. In this Special Issue, original research articles and review articles are welcome.

The Genus of a Graph: A Survey
✏️Liangxia Wan

The problem of determining the genus for a graph can be dated to the Map Color Conjecture proposed by Heawood in 1890. This was implied to be a Thread Problem by Hilbert and Cohn-Vossen. The conjecture was finally established by Ringel, Youngs, and many other mathematicians. Subsequently, the genera of some special graphs with symmetry were determined. The study of genus embeddings of graphs is closely related to other invariants of a graph. Specifically, the computational complexity is dependent on the genus of the underlying graph for certain well-known NP-hard problems. In this survey, main construction techniques and certain criteria are stated in the topic of the genus of a graph. Most graphs with a known genus are listed.

We are glad to announce the closure of the Special Issue:
Title: Symmetry in Geometric Theory of Analytic Functions
Editor: Dr. Daciana Alina Alb Lupas
Details: https://brnw.ch/21wXCzn

The aim of the present Special Issue is to exchange ideas among eminent mathematicians globally as a tribute to the geometric function theory. We hope that this Special Issue will boost cooperation among mathematicians working on a broad variety of pure and applied mathematical areas. In this Special Issue made up of ideas and mathematical methods, we aim to include a wide area of applications in which the geometric function theory plays an important role, resulting in having an extreme influence on everyday life, as the development of new tools means revolutionary research results have been obtained, bringing scientists even closer to exact science and encouraging the emergence of new approaches, techniques, and perspectives in complex analysis.

Pulsar Kick: Status and Perspective

🔗https://www.mdpi.com/3086994
Viewed: 1211; Cited: 4

The high speeds seen in rapidly rotating pulsars after supernova explosions present a longstanding puzzle in astrophysics. Numerous theories have been suggested over the years to explain this sudden “kick” imparted to the neutron star, yet each comes with its own set of challenges and limitations. Key explanations for pulsar kicks include hydrodynamic instabilities in supernovae, anisotropic neutrino emission, asymmetries in the magnetic field, binary system disruption, and physics beyond the Standard Model. Unraveling the origins of pulsar kicks not only enhances our understanding of supernova mechanisms but also opens up possibilities for exploring new physics. In this brief review, we will introduce pulsar kicks, examine the leading hypotheses, and explore future directions for this intriguing phenomenon.
