غزواتِ نبویہ ﷺ میں اہلِ کتاب کے ساتھ اخلاقِ حسنہ کے مظاہر Manifestations of Akhlaq-e-Hasanah (good manners) with the People of the Book (Ehl-e-Kitab) in Ghazwat-e-Nabawiyyah ﷺ

When we study about the life of Holy Prophet (ﷺ), his life demand from Muslims to protect the dignity and honour of their Muslim brothers. They not only protect or care the right of their Muslim brothers in their life but also protect their dignity after their death. In the light of Holy Prophet Life the circle of human rights is so vast. In this, his life teaches us the turidicul, rights, marriage, settlement different between good or evil, isonomy and the verses of martyr and the noble behaviour with Jews and Christians. There is a big role of ethics on the human personality. The ethics is the tester of good or bad person Human with the noble ethics the Muslims. To be remembered as staying up all the night and to fast. The ethics play important role in the life of Human. In the life of Prophet (ﷺ) we know about his good deeds and noble behavior with non Muslims. The success of the Holy Prophet preaching is only because of his ethics and truthness. Islam Universal Religion. It’s Teachings and pregnative system is the everlasting. In this modern period there is no way except Islam to get Rid the unsolved problems of the age. The beloved Prophet (ﷺ) “Sira Mubarak” the way of light only. There is aspect of the life without the real pregnative system. Peace and the War both are in the teaching of the Holy Prophet (ﷺ). Peace, progress contentment, satisfaction, true, unity, brotherhood in the lightment of the “Uswa Hasna”. Let’s seek the real way in our beloved Prophet (ﷺ). Key Words: Holy Prophet, Ghazwa, Akhlaq-e-Hasanah, Ehl-e-Kitab, War, Ethics.

Spatio-Temporal Wave Packet Dynamics in Fermi-Ulam Accelerator

The idea of wave packet, that clarified many conceptual difficulties, has more recently been revisited to address interferometric and dynamical issues. Present work focuses on the spatio-temporal dynamics of the quantum wave packets in the Fermi-Ulam Accelerator Model. The specific system considered here is a one-dimensional box under periodic oscillations at one boundary. Such a seemingly simple system can be mapped to non-trivial problems like BEC trapped in an oscillating cavity or dynamics of atomic wave packet in different potential in presence or absence of gravitational field. The system is shown to display rich dynamical features including transitions from regular to stochastic and further to chaotic domain in classical phase space. We have obtained the approximated eigen-value solutions of the problem through time dependent Schrodinger’s equation under rescaling transformations that effectively replace moving boundary with a static one. Consequently the running time becomes a nonlinear function of the continuously changing boundary. Based on these solutions, revivals or the resurrection of the original wave packet, in the driven and un-driven Fermi-Ulam model are presented. Such revivals correspond to the constructive interference whereas the wave packet’s collapse owes to destructive interference. Furthermore, interplay of constructive and destructive interferences also readily mimics the fractional revivals. It is further demonstrated that initial position and momentum play a highly crucial role in the emergent revival and fractional revival patterns. It is shown that the symmetries exhibited by such structures in un-driven systems are usually lost under driven conditions and the revival/fractional revival times can only be predicted through a transcendental equation whose solution mainly depends on the strength of the external driving force. In present thesis we have proposed a comprehensive mathematical technique to calculate these hitherto unpredictable times. In addition, a graphical method is also suggested to observe these asymmetric revival/fractional revival times. This apparent asymmetry, do display an overall periodicity over a comparatively long span covering many times of revivals. It is found that whenever the ratio between the period of wall oscillation and quantum revival time `α/β'' is a rational number then the revivals time shows a periodicity after β viinumber of revival times over α wall oscillation. Standard tools of autocorrelation and quantum carpets, a consequence of quantum interference, have been employed for visual manifestation of these revivals. These carpets amply demonstrate the explicit asymmetric shifting of revival times for the driven case. These micro changes exhibited in quantum carpet morphologies consequently yield amended phase velocities associated with the canals and ridges in the driven framework. Furthermore, to grasp the quantum phase space dynamics in its entirety, we have also utilized the more sophisticated techniques of the Wigner function and information entropy. It is demonstrated mathematically that revivals not apparent via autocorrelation become prominent in the Wigner phase space description along with the appearance of smooth mini wave packets in the fractional revivals. These interference patterns emerge due to the state vector formed through the linear combination of Gaussians with different positions and momenta having pure Gaussian as well as oscillatory terms. Moreover, the information entropy, like the Wigner function also predicts the revivals when and where they happen. Thus a rich pattern of fractional revivals, including some altogether new ones, are observed through this tool in both driven and un-driven situations. Finally we have elucidated various scenarios including cold atoms in magneto-optical traps where such a system can be experimentally realized along with the suggestions for future work in this specific domain.
