Low temperature dynamics of nonlinear Luttinger liquids
C. Karrasch, R. G. Pereira, J. Sirker
We generalize nonlinear Luttinger liquid theory to describe the dynamics of one-dimensional quantum critical systems at low temperatures. Analyzing density-matrix renormalization g…

Boundary Fidelity and Entanglement in the symmetry protected topological phase of the SSH model
J. Sirker, M. Maiti, N. P. Konstantinidis +1
We present a detailed study of the fidelity, the entanglement entropy, and the entanglement spectrum, for a dimerized chain of spinless fermions---a simplified Su-Schrieffer-Heeger…
