Supersolid phases in the extended boson hubbard model
Kwai-Kong Ng, Y. C. Chen
We present a comprehensive numerical study on the ground state phase diagram of the two-dimensional hardcore boson extended Hubbard model with nearest () and next nearest neig…
Quantum Phase Transitions and the Hidden Order in a Two-Chain Extended Boson Hubbard Model at Half-Odd-Integer Fillings
Yu-Wen Lee
We study the phase diagram of two weakly coupled one-dimensional dipolar boson chains at half-odd-integer fillings. We find that the system contains a rich phase diagram. Four diff…
Scaling Properties of Fidelity in Spin-one Anisotropic Model
Yu-Chin Tzeng, Min-Fong Yang
By means of the density matrix renormalization group technique, the scaling relation of the fidelity susceptibility proposed recently is verified for the spin-one XXZ spin chain wi…
Point Mutations Effects on Charge Transport Properties of the Tumor-Suppressor Gene p53
Chi-Tin Shih, Stephan Roche, Rudolf A. Römer
We report on a theoretical study of point mutations effects on charge transfer properties in the DNA sequence of the tumor-suppressor p53 gene. On the basis of effective single-str…
Commensurate lock-in and incommensurate supersolid phases of hardcore bosons on anisotropic triangular lattices
Sergei V. Isakov, Hong-Chi Chien, Jian-Jheng Wu +4
We investigate the interplay between commensurate lock-in and incommensurate supersolid phases of the hardcore bosons at half-filling with anisotropic nearest-neighbor hopping and…
Ground-state fidelity in one-dimensional gapless model
Min-Fong Yang
A general relation between quantum phase transitions and the second derivative of the fidelity (or the "fidelity susceptibility") is proposed. The validity and the limitation of th…
