$\kappa$-deformed Dirac Equation

, 2009
We construct a Dirac equation in $\kappa$-Minkowski spacetime and analyse its implications. This $\kappa$-deformed Dirac equation is expanded as a power series involving derivatives with respect to commutative coordinates and the deformation parameter, $a$.

Mapping of Physiological Signals From Wireless Battery‐Free Implants With Plane‐Wave Ultrasound Imaging

Advanced Materials Technologies, EarlyView.
Combined approach of electromagnetic (Power) and ultrasound (data harvesting) waves is proposed to address the miniaturized ultrasonic implants. Electromagnetic waves trigger the piezoelectric element to generate the acoustic pulse which is modulated by the variations in the sensor's impedance.

Ultrabroadband Excitation of Hot Carriers in Plasmonic Nanorods Revealed by Two‐Dimensional Electronic Spectroscopy

Advanced Optical Materials, EarlyView.
This work dissects the ultrafast response of polydisperse plasmonic nanorods using two‐dimensional electronic spectroscopy, uniquely combining temporal and spectral resolution. Our ultrabroadband pulses cover both transverse and longitudinal nanorods’ resonances, revealing sub‐200‐fs dynamics and distinct broadening mechanisms.

Quasi-exact solvable Dirac equation for the generalized Cornell potential plus a novel angle-dependent potential

Journal of Innovative Applied Mathematics and Computational Sciences
In this paper, we present the exact analytical solution of the Dirac equation with equal scalar and vector generalized Cornell potential plus a novel angle-dependent potential in the framework of quasi-exactly solvable problems.

A Covalent 3D CNT@rGO Nano‐Hybrid for High‐Efficiency Conductivity in Lithium‐Ion Batteries

Advanced Science, EarlyView.
A facile one‐step CVD strategy achieves high‐yield (7692.31%) growth of CNTs on rGO, forming a covalently bonded 3D CNT@rGO hybrid. This structure enables multidirectional conductive networks in LiFePO4 cathodes, delivering superior rate performance, high ICE (99.88%), and 96.32% capacity retention after 300 cycles at 1 C.

On Huygens' principle for Dirac operators associated to electromagnetic fields

Anais da Academia Brasileira de Ciências, 2001
We study the behavior of massless Dirac particles, i.e., solutions of the Dirac equation with m = 0 in the presence of an electromagnetic field. Our main result (Theorem 1) is that for purely real or imaginary fields any Huygens type (in Hadamard's sense)

Dirac Equation in the Presence of Hartmann and Ring-Shaped Oscillator Potentials

Advances in High Energy Physics, 2018
The importance of the energy spectrum of bound states and their restrictions in quantum mechanics due to the different methods have been used for calculating and determining the limit of them.
