Dynamics of quantum discommensurations in the Frenkel-Kontorova chain
Oksana Chelpanova, Shane P. Kelly, Ferdinand Schmidt-Kaler +2
The ability for real-time control of topological defects can open up prospects for dynamical manipulation of macroscopic properties of solids. A sub-category of these defects, form…
Injection and nucleation of topological defects in the quench dynamics of the Frenkel-Kontorova model
Oksana Chelpanova, Shane P. Kelly, Giovanna Morigi +2
Topological defects have strong impact on both elastic and inelastic properties of materials. In this article, we investigate the possibility to controllably inject topological def…
Zeno crossovers in the entanglement speed of spin chains with noisy impurities
Abhijit P. Chaudhari, Shane P. Kelly, Riccardo J. Valencia-Tortora +1
We use a noisy signal with finite correlation time to drive a spin (dissipative impurity) in the quantum XY spin chain and calculate the dynamics of entanglement entropy of a bipar…
