Scaling of excitations in dimerized and frustrated spin-1/2 chains
D. Controzzi, C. Degli Esposti Boschi, F. Ortolani +1
We study the finite-size behavior of the low-lying excitations of spin-1/2 Heisenberg chains with dimerization and next-to-nearest neighbors interaction, J_2. The numerical analysi…

Dynamical Properties of one dimensional Mott Insulators
Davide Controzzi, Fabian H. L. Essler, Alexei M. Tsvelik
At low energies the charge sector of one dimensional Mott insulators can be described in terms of a quantum Sine-Gordon model. Using exact results derived from integrability it is…
