Ashkin-Teller formalism for elastic response of DNA molecule to external force and torque
Zhe Chang, Ping Wang, Ying-Hong Zheng
We propose an Ashkin-Teller like model for elastic response of DNA molecule to external force and torque. The base-stacking interaction is described in a simple and uniform way. We…

Topology Changes and Quantum Phase Transition in Spin-Chain System
Zhe Chang, Ping Wang
The standard Landau-Ginzburg scenario of phase transition is broken down for quantum phase transition. It is difficult to find an order parameter to indicate different phases for q…
