Query: Strong-Coupling Behavior of Two $t-J$ Chains with Interchain Single
  Electron Hopping   Using the fermion-spin transformation to implement spin-charge separation of
constrained electrons, a model of two $t-J$ chains with interchain
single-electron hopping is studied by abelian bosonization. After spin-charge
decoupling the charge dynamics can be trivially solved, while the spin dynamics
is determined by a strong-coupling fixed point where the correlation functions
can be calculated explicitly. This is a generalization of the Luther-Emery line
for two-coupled $t-J$ chains. The interchain single-electron hopping changes
the asymptotic behavior of the interchain spin-spin correlation functions and
the electron Green function, but their exponents are independent of the
coupling strength.
