Long-range doublon transfer in a dimer chain induced by topology and ac fields

M Bello, CE Creffield, G Platero - Scientific Reports, 2016 - nature.com
The controlled transfer of particles from one site of a spatial lattice to another is essential for
many tasks in quantum information processing and quantum communication. In this work we …

State-recycling and time-resolved imaging in topological photonic lattices

S Mukherjee, HK Chandrasekharan, P Öhberg… - Nature …, 2018 - nature.com
Photonic lattices—arrays of optical waveguides—are powerful platforms for simulating a
range of phenomena, including topological phases. While probing dynamics is possible in …

Quantum control and entanglement using periodic driving fields

CE Creffield - Physical review letters, 2007 - APS
We propose a scheme for producing directed motion in a lattice system by applying a
periodic driving potential. By controlling the dynamics by means of the effect known as …

Observation of pair tunneling and coherent destruction of tunneling in arrays of optical waveguides

S Mukherjee, M Valiente, N Goldman, A Spracklen… - Physical Review A, 2016 - APS
We report on the experimental realization of a photonic system that simulates the one-
dimensional two-particle Hubbard model. This analogy is realized by means of two …

Topological bound states in interacting Su–Schrieffer–Heeger rings

AM Marques, RG Dias - Journal of Physics: Condensed Matter, 2018 - iopscience.iop.org
We study two-particle states in a Su–Schrieffer–Heeger (SSH) chain with periodic boundary
conditions and nearest-neighbor (NN) interactions. The system is mapped into a problem of …

Simulation of 1d topological phases in driven quantum dot arrays

B Pérez-González, M Bello, G Platero… - Physical Review Letters, 2019 - APS
We propose a driving protocol which allows us to use quantum dot arrays as quantum
simulators for 1D topological phases. We show that by driving the system out of equilibrium …

Correlated super-Bloch oscillations

The coherent dynamics of two strongly interacting electrons hopping on a one-dimensional
lattice and driven by combined dc-ac fields is theoretically investigated in the framework of …

Coherent control of interacting particles using dynamical and Aharonov-Bohm Phases

CE Creffield, G Platero - Physical review letters, 2010 - APS
A powerful method of manipulating the dynamics of quantum coherent particles is to control
the phase of their tunneling. We consider a system of two electrons hopping on a quasi-one …

Floquet engineering of long-range -wave superconductivity: Beyond the high-frequency limit
