Exploring the implications of the laws and principles of quantum physics in the field of talent (quantum theory of talent)
The issue of talent-discovering is one of the most important issues in the field of education and research that has always been a concern for educational systems. Studying the issues of identifying and guiding talented students can illuminate a large part of the activities of the executors and practitioners in order to accomplish their mission effectively. On the other hand, quantum physics has...
متن کاملTheory of taro - dimensional quantum Heisenberg antiferromagnets arith a nearly critical ground state
%'e present the general theory of clean, two-dimensional, quantum Heisenberg antiferromagnets which are close to the zero-temperature quantum transition between ground states with and without long-range Neel order. While some of our discussion is more general, the bulk of our theory will be restricted to antiferromagnets in which the Neel order is described by a three-vector order parameter. Fo...
متن کاملTheory of two-dimensional quantum Heisenberg antiferromagnets with a nearly critical ground state.
We present the general theory of clean, two-dimensional, quantum Heisenberg antiferromagnets which are close to the zero-temperature quantum transition between ground states with and without long-range Néel order. While some of our discussion is more general, the bulk of our theory will be restricted to antiferromagnets in which the Néel order is described by a 3-vector order parameter. For Née...
متن کاملCombined effects of pressure, temperature, and magnetic field on the ground state of donor impurities in a GaAs/AlGaAs quantum heterostructure
In the present work, the exact diagonalization method had been implemented to calculate the ground state energy of shallow donor impurity located at finite distance along the growth axis in GaAs/AlGaAs heterostructure in the presence of a magnetic field taken to be along z direction. The impurity binding energy of the ground state had been calculated as a function of confining frequency and mag...
متن کاملEfficient Algorithm for Optimal Control of Mixed-State Quantum Systems
Much work has recently been done on control of pure-state quantum systems using the traditional wavefunction formalism [?,?,?]. This work is most important; however many physical systems, such as systems initially in thermal equilibrium or otherwise described by an ensemble of states, or systems where dissipative processes are significant, can not be treated using this approach. Therefore, a de...
