Impurity dephasing in a Bose-Hubbard model
Fabio Caleffi, Massimo Capone, Inés de Vega +1
We study the dynamics of a two-level impurity embedded in a two-dimensional Bose-Hubbard model at zero temperature from an open quantum system perspective. Results for the decohere…
The quantum dynamical map of the spin boson model
Inés de Vega
One of the main frameworks to analyze the effects of the environment in a quantum computer is that of pure dephasing, where the dynamics of qubits can be characterised in terms of…
Nonreciprocal Quantum Transport at Junctions of Structured Leads
Eduardo Mascarenhas, François Damanet, Stuart Flannigan +4
We propose and analyze a mechanism for rectification of spin transport through a small junction between two spin baths or leads. For interacting baths we show that transport is con…
Quantum Critical Probing and Simulation of Colored Quantum Noise
Eduardo Mascarenhas, Ines de Vega
We propose a protocol to simulate the evolution of a non-Markovian open quantum system by considering a collisional process with a many-body system, which plays the role of an envi…
Collective dynamics of accelerated atoms
Benedikt Richter, Hugo Terças, Yasser Omar +1
We study the collective dynamics of accelerated atoms interacting with a massless field via an Unruh-deWitt-type interaction. We first derive a general Hamiltonian describing such…
State Transfer in Highly Connected Networks and a Quantum Babinet Principle
D. I. Tsomokos, M. B. Plenio, I. de Vega +1
The transfer of a quantum state between distant nodes in two-dimensional networks, is considered. The fidelity of state transfer is calculated as a function of the number of intera…
