Nb2CBr2 MXene Monolayer as a Novel Material: A First Principle Study

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 2, February 2026.
Illustration of the monolayer cell, cell replicated in directions a and b, graph of optical absorption and thermodynamic potentials as a function of temperature. Abstract Niobium‐based MXenes show promising properties and applications, but have not yet been sufficiently investigated, especially with halogen surface terminations. This study investigates

Mass radius relation of compact stars in the braneworld

open access: yes, 2014
The braneworld scenario, based on the fact that the four dimension space-time is a hyper-surface of a five dimensional manifold, was shown to deal in a satisfactory way with the hierarchy problem.

Screw‐Dislocation‐Engineered Quantum Dot: Geometry‐Tunable Nonlinear Optics, Orbital Qubit Addressability, and Torsion Metrology

open access: yesAnnalen der Physik, Volume 538, Issue 2, February 2026.
A uniform torsion field—representing a controlled density of parallel screw dislocations—confines a single electron into a geometry‐defined quantum dot. In a perpendicular magnetic field, an Aharonov–Bohm flux breaks the m↔−m$m \leftrightarrow -m$ symmetry and yields a flux‐ and torsion‐tunable angular pseudospin (m=±1)$(m = \pm 1)$ with asymmetric ...

Quantum dynamics of a spin-1/2 charged particle in the presence of magnetic field with scalar and vector couplings

open access: yes, 2015
The quantum dynamics of a spin-1/2 charged particle in the presence of magnetic field is analyzed for the general case where scalar and vector couplings are considered. The energy spectra are explicitly computed for different physical situations, as well
