Anisotropic Fermi Superfluid via p-wave Feshbach Resonance
Chi-Ho Cheng, S. -K. Yip
We investigate theoretically Fermionic superfluidity induced by Feshbach resonance in the orbital p-wave channel. We show that, due to the dipole interaction, the pairing is extrem…
Conformational Properties of an Adsorbed Charged Polymer
Chi-Ho Cheng, Pik-Yin Lai
The behavior of a strongly charged polymer adsorbed on an oppositely charged surface of low-dielectric constant is formulated by the functional integral method. By separating the t…
Adsorption Transition of a Polyelectrolyte on a High-dielectric Charged Substrate
Chi-Ho Cheng, Pik-Yin Lai
The behavior of a polyelectrolyte adsorbed on a charged surface of high-dielectric constant is studied by both Monte-Carlo simulation and analytical methods. It is found that in a…
Polyelectrolyte Adsorption on Charged Substrate
Chi-Ho Cheng, Pik-Yin Lai
The behavior of a polyelectrolyte adsorbed on a charged substrate of high-dielectric constant is studied by both Monte-Carlo simulation and analytical methods. It is found that in…
Supersymmetric Mean-Field Theory of t-J Model
Chi-Ho Cheng, T. K. Ng
The supersymmetric formulation of t-J model is studied in this paper at the mean-field level where -T phase diagram is computed. We find that slave-fermion-like spiral phase is…
Supersymmetry in models with strong on-site Coulomb repulsion - application to t-J model
T. K. Ng, Chi-Ho Cheng
A supersymmetric way of imposing the constraint of no double occupancy in models with strong on-site Coulomb repulsion is presented in this paper. In this formulation the physical…
