Cluster-Impact Fusion and Effective Deuteron Temperature
Y. E. Kim, J. -H. Yoon, R. A. Rice +1
Temperature and kinematic line broadening are the primary contributions to the width of the proton energy spectrum measured in cluster-impact fusion experiments. By ascertaining th…
Singlet Stripe Phases in the planar t-J Model
Hirokazu Tsunetsugu, Matthias Troyer, T. M. Rice
The energies of singlet stripe phases in which a plane is broken up into spin liquid ladders by lines of holes, is examined. If the holes were static then patterns containing spin…
Pairing and Excitation Spectrum in doped t-J Ladders
Hirokazu Tsunetsugu, Matthias Troyer, T. Maurice Rice
Exact diagonalization studies for a doped t-J ladder (or double chain) show hole pairing in the ground state. The excitation spectrum separates into a limited number of quasipartic…
Spin Gap and Superconductivity in the One-Dimensional t-J Model with Coulomb Repulsion
M. Troyer, H. Tsunetsugu, T. M. Rice +2
The one-dimensional t-J model with density-density repulsive interactions is investigated using exact diagonalization and quantum Monte Carlo methods. A short-range repulsion pushe…
