Nonlinear sigma model of a spin ladder containing a static single hole
نویسنده
چکیده
In this letter we extend the nonlinear σ model describing pure spin ladders with an arbitrary number of legs to the case of ladders containing a single static hole. A simple immediate application of this approach to classical ladders is worked out. PACS numbers: 75.50.Ee; 75.10.Jm; 75.10.Hk; 75.30.Ds

Static holes in the geometrically frustrated bow-tie ladder
We investigate the doping of a geometrically frustrated spin ladder with static holes by a complementary approach using exact diagonalization and quantum dimers. Results for thermodynamic properties, the singlet density of states, the hole-binding energy and the spin correlations will be presented. For the undoped systems the ground state is non-degenerate, with translationally invariant neares...

We utilize the path-integral technique to derive the non-linear Sigma model (NLsM) for generalized antiferromagnetic spin-ladder systems on the square lattice with diagonal (next-nearest neighbor) interactions in addition to the nearest neighbor interaction. The model Hamiltonian is:H 1⁄4 Pnl a1⁄41 P i JaSaðiÞ Saði þ 1Þ þ J 0 a;aþ1SaðiÞ Saþ1ðiÞ þ Ka;aþ1SaðiÞ Saþ1ði þ 1Þ þMa;aþ1Saði þ 1Þ SaðiÞ: ...
متن کاملSuperconductivity versus Tunneling in a Doped Antiferromagnetic Ladder
The low-energy charge excitations of a doped antiferromagnetic ladder are modeled by a system of interacting spinless fermions that live on the same ladder. A relatively large spin gap is assumed to “freeze out” all spin fluctuations. We find that the formation of rung hole pairs coincides with the opening of a single-particle gap for charge excitations along chains and with the absence of cohe...

متن کاملThe Non-Linear Sigma Model and Spin Ladders
The well known Haldane map from spin chains into the O(3) non linear sigma model is generalized to the case of spin ladders. This map allows us to explain the different qualitative behaviour between even and odd ladders, exactly in the same way it explains the difference between integer and half-integer spin chains. Namely, for even ladders the topological term in the sigma model action is abse...
