In this talk we introduce some recent developments of Heisenberg-Pauli-Weyl uncertainty principle in the different settings.
Quantum criticality in the SO(5) bilinear-biquadratic Heisenberg chain
Quantum criticality SO(5) bilinear-biquadratic Heisenberg chain
2010/11/18
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 ...
Very High Precision Determination of Low-Energy Parameters: The 2-d Heisenberg Quantum Antiferromagnet as a Test Case
Very High Precision Determination of Low-Energy Paraameters 2-d Heisenberg Quantum Antiferromagnet Test Case
2011/1/14
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 ...
Controlling qubit arrays with anisotropic XXZ Heisenberg interaction by acting on a single qubit
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...
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.
