Lieb-Robinson bounds and the speed of light from topological order
Alioscia Hamma, Fotini Markopoulou, Isabeau Premont-Schwarz +1
We apply the Lieb-Robinson bounds technique to find the maximum speed of interaction in a spin model with topological order whose low-energy effective theory describes light [see X…
Adiabatic approximation with exponential accuracy for many-body systems and quantum computation
D. A. Lidar, A. T. Rezakhani, A. Hamma
We derive a version of the adiabatic theorem that is especially suited for applications in adiabatic quantum computation, where it is reasonable to assume that the adiabatic interp…

Fidelity analysis of topological quantum phase transitions
Damian F. Abasto, Alioscia Hamma, Paolo Zanardi
We apply the fidelity metric approach to analyze two recently introduced models that exhibit a quantum phase transition to a topologically ordered phase. These quantum models have…
