In this talk we introduce some recent developments of Heisenberg-Pauli-Weyl uncertainty principle in the different settings.
We consider the mean-field classical Heisenberg model and obtain detailed information about the magnetization by studying the model on a complete graph and sending the number of vertices to infinity. ...
The zero-temperature properties of the SO(5) bilinear-biquadratic Heisenberg spin chain are investigated by means of a low-energy approach and large scale numerical calculations. In sharp contrast to ...
The 2-d spin 1 2 Heisenberg antiferromagnet with exchange coupling J is investigated on a periodic square lattice of spacing a at very small temperatures using the loop-cluster algorithm. Monte Carlo ...
We investigate anisotropic $XXZ$ Heisenberg spin-1/2 chains with control fields acting on one of the end spins, with the aim of exploring local quantum control in arrays of interacting qubits. In this...
The E2 algebra has three elements, J, u, and v, which satisfy the commutation relations [u; J] = iv, [v; J] = 􀀀iu, [u; v] = 0. We can construct the Hamiltonian H = J2 +gu, where g is a real p...
The thermal quantum discord (QD) is studied in a two-qubit Heisenberg XXZ system with Dzyaloshinskii-Moriya (DM) interaction. We compare the thermal QD with thermal entanglement in this system and fin...
The Nobel Prize in Physics 1932, Werner Karl Heisenberg, for the creation of quantum mechanics, the application of which has, inter alia, led to the discovery of the allotropic forms of hydrogen.
本文给出了二维Heisenberg反铁磁系统中的正则变换.在此变换下发现二维Heisenberg反铁磁模型在连续极限下是具有拓扑项的O(3)非线性σ模型.由于在选取正则变量时有很大的不确定性,因此还不能判定此系统是否确有拓扑项存在.最后对正则变换的物理意义进行了研究,发现它体现了系统自旋的集体激发,表明存在着一种自旋波.
从独立算符和的Heisenberg表示的本征值方程出发,利用其乘法规则,由简到繁,由公式到实例,给出了两个任意有限维独立算符和的Heisenberg矩阵表达式,它可作为相关问题研究直接可用的公式,也为本科量子力学教材的扩充提供了素材。
