Abstract
Based on the one-dimensional extended Hubbard model ( t - U - V ), we study the ground state characteristics of the one-dimensional t - U - V - P model by adding a diagonal three-body interaction ( P ). Using the bosonization approach and renormalization group theory, we obtain a ground-state phase diagram of the model at half-filling. The result shows that the three-body interaction modifies the struc-*
期刊介绍:
Advances in Condensed Matter Physics publishes articles on the experimental and theoretical study of the physics of materials in solid, liquid, amorphous, and exotic states. Papers consider the quantum, classical, and statistical mechanics of materials; their structure, dynamics, and phase transitions; and their magnetic, electronic, thermal, and optical properties.
Submission of original research, and focused review articles, is welcomed from researchers from across the entire condensed matter physics community.
