Superfluid density and quasi-long-range order in the one-dimensional disordered Bose-Hubbard model
Matthias Gerster, Matteo Rizzi, Ferdinand Tschirsich +3
We study the equilibrium properties of the one-dimensional disordered Bose-Hubbard model by means of a gauge-adaptive tree tensor network variational method suitable for systems wi…
On the complexity of controlling quantum many-body dynamics
T. Caneva, A. Silva, R. Fazio +3
We demonstrate that arbitrary time evolutions of many-body quantum systems can be reversed even in cases when only part of the Hamiltonian can be controlled. The reversed dynamics…
Speeding up critical system dynamics through optimized evolution
T. Caneva, T. Calarco, R. Fazio +2
The number of defects which are generated on crossing a quantum phase transition can be minimized by choosing properly designed time-dependent pulses. In this work we determine wha…
Quantum Billiards in Optical Lattices
Simone Montangero, Diego Frustaglia, Tommaso Calarco +1
We study finite two dimensional spin lattices with definite geometry (spin billiards) demonstrating the display of collective integrable or chaotic dynamics depending on their shap…
Cloning transformations in spin networks without external control
G. De Chiara, R. Fazio, C. Macchiavello +2
In this paper we present an approach to quantum cloning with unmodulated spin networks. The cloner is realized by a proper design of the network and a choice of the coupling betwee…
Entanglement production by quantum error correction in the presence of correlated environment
G. De Chiara, R. Fazio, C. Macchiavello +1
We analyze the effect of a quantum error correcting code on the entanglement of encoded logical qubits in the presence of a dephasing interaction with a correlated environment. Suc…
