Excitonic diffusion length in complex quantum systems: The effects of disorder and environmental fluctuations on symmetry-enhanced supertransfer
Damian F. Abasto, Masoud Mohseni, Seth Lloyd +1
Symmetric couplings among aggregates of chromophores increase the transfer rate of excitons by a factor , a quantum mechanical phenomenon called "supertransfer." In this w…
Intrinsic geometry of quantum adiabatic evolution and quantum phase transitions
Ali T. Rezakhani, Damian F. Abasto, Daniel A. Lidar +1
We elucidate the geometry of quantum adiabatic evolution. By minimizing the deviation from adiabaticity we find a Riemannian metric tensor underlying adiabatic evolution. Equipped…
Fidelity in topological quantum phases of matter
Silvano Garnerone, Damian Abasto, Stephan Haas +1
Quantum phase transitions that take place between two distinct topological phases remain an unexplored area for the applicability of the fidelity approach. Here, we apply this meth…
Thermal states of the Kitaev honeycomb model: a Bures metric analysis
Damian F. Abasto, Paolo Zanardi
We analyze the Bures metric over the canonical thermal states for the Kitaev honeycomb mode. In this way the effects of finite temperature on topological phase transitions can be s…
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…
Quantum Chernoff Bound metric for the XY model at finite temperature
Damian F. Abasto, N. Tobias Jacobson, Paolo Zanardi
We explore the finite temperature phase diagram of the anisotropic XY spin chain using the Quantum Chernoff Bound metric on thermal states. The analysis of the metric elements allo…
