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 ...
Bilinear approach to the quasi-periodic wave solutions of supersymmetric equations in superspace
quasi-periodic wave superspace supersymmetric equations
2010/4/1
We devise a lucid and straightforward way for explicitly constructing quasi-periodic wave solutions (also called multi-periodic wave solutions) of supersymmetric equations in superspace $\mathbb{R}_\L...
