In this talk we introduce some recent developments of Heisenberg-Pauli-Weyl uncertainty principle in the different settings.
Asymptotics of the mean-field Heisenberg model
Asymptotics the mean-field Heisenberg model Mathematical Physics
2012/4/16
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. ...

Controlling qubit arrays anisotropic XXZ Heisenberg interaction acting single qubit
2010/11/9
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...
Extending PT symmetry from Heisenberg algebra to E2 algebra
Extending PT symmetry Heisenberg algebra E2 algebra
2010/10/27
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...
Thermal quantum discord in the anisotropic Heisenberg XXZ model with the Dzyaloshinskii-Moriya interaction
quantum discord Dzyaloshinskii-Moriya anisotropic Heisenberg XXZ
2010/3/10
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.
二维Heisenberg反铁磁系统中的正则变换和自旋波
自旋波 正则变换 反铁磁 二维Heisenberg
2009/7/7
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.
