Ground state and excitation of an asymmetric spin ladder model
Shu Chen, H. Büttner, J. Voit
We perform a systematic investigation of an asymmetric zig-zag spin ladder with inter-leg exchange and different exchange integrals on both legs. In the weak limi…
Phase diagram of an asymmetric spin ladder
Shu Chen, H. Buettner, J. Voit
We investigate an asymmetric zig-zag spin ladder with different exchange integrals on both legs using bosonization and renormalization group. When the leg exchange integrals and fr…
Lattice Twisting Operators and Vertex Operators in Sine-Gordon Theory in One Dimension
Masaaki Nakamura, Johannes Voit
In one dimension, the exponential position operators introduced in a theory of polarization are identified with the twisting operators appearing in the Lieb-Schultz-Mattis argument…
A brief introduction to Luttinger liquids
Johannes Voit
I give a brief introduction to Luttinger liquids. Luttinger liquids are paramagnetic one-dimensional metals without Landau quasi-particle excitations. The elementary excitations ar…
Bounded Luttinger liquids as a universality class of quantum critical behavior
Johannes Voit, Yupeng Wang, Marco Grioni
We show that one-dimensional quantum systems with gapless degrees of freedom and open boundary conditions form a new universality class of quantum critical behavior, which we propo…
Dynamical correlation functions of one-dimensional superconductors and Peierls and Mott insulators
Johannes Voit
I construct the spectral function of the Luther-Emery model which describes one-dimensional fermions with one gapless and one gapped degree of freedom, i.e. superconductors and Pei…
