Extracting Kinetic Information from Short-Time Trajectories: Relaxation and Disorder of Lossy Cavity Polaritons
Andrew Wu, Javier Cerrillo, Jianshu Cao
The emerging field of molecular cavity polaritons has stimulated a surge of experimental and theoretical activities and presents a unique opportunity to develop the many-body simul…
Low frequency signal detection via correlated Ramsey measurements
Santiago Oviedo-Casado, Javier Prior, Javier Cerrillo
The low frequency region of the spectrum is a challenging regime for quantum probes. We support the idea that, in this regime, performing Ramsey measurements carefully controlling…
Formation of Two-Ion Crystals by Injection from a Paul-Trap Source into a High-Magnetic-Field Penning Trap
Joaquín Berrocal, Emilio Altozano, Francisco Domínguez +6
Two-ion crystals constitute a platform for investigations of quantum nature that can be extended to any ion species or charged particle provided one of the ions in the crystal can…
Production of Fock Mixtures in Trapped Ions for Motional Metrology
Antonis Delakouras, Daniel Rodríguez, Javier Cerrillo
We present a protocol to produce a class of non-thermal Fock state mixtures in trapped ions. This class of states features a clear metrological advantage with respect to the ground…
Zero- and Low-Field Sensing with Nitrogen Vacancy Centers
Philipp J. Vetter, Alastair Marshall, Genko T. Genov +8
Over the years, an enormous effort has been made to establish nitrogen vacancy (NV) centers in diamond as easily accessible and precise magnetic field sensors. However, most of the…
Low field nano-NMR via three-level system control
Javier Cerrillo, Santiago Oviedo Casado, Javier Prior
Conventional control strategies for NV centers in quantum sensing are based on a two-level model of their triplet ground state. However, this approach fails in regimes of weak bias…
Electron pumping in the strong coupling and non-Markovian regime: A reaction coordinate mapping approach
Sebastian Restrepo, Sina Böhling, Javier Cerrillo +1
We study electron pumping in the strong coupling and non-Markovian regime. Our model is a single quantum dot with periodically modulated energy and tunnelling amplitudes. We identi…
From quantum heat engines to laser cooling: Floquet theory beyond the Born-Markov approximation
Sebastian Restrepo, Javier Cerrillo, Philipp Strasberg +1
We combine the formalisms of Floquet theory and full counting statistics with a Markovian embedding strategy to access the dynamics and thermodynamics of a periodically driven ther…
Multi-mode double-bright EIT cooling
Nils Scharnhorst, Javier Cerrillo, Johannes Kramer +4
We developed a multi-mode ground state cooling technique based on electromagnetically-induced transparency (EIT). By involving an additional ground and excited state, two individua…
Experimental and theoretical investigation of a multi-mode cooling scheme using multiple EIT resonances
Nils Scharnhorst, Javier Cerrillo, Johannes Kramer +4
We introduce and demonstrate double-bright electromagnetically induced transparency (D-EIT) cooling as a novel approach to EIT cooling. By involving an additional ground state, two…
Initial System-Environment Correlations via the Transfer Tensor Method
Maximilian Buser, Javier Cerrillo, Gernot Schaller +1
Open quantum systems exhibiting initial system-environment correlations are notoriously difficult to simulate. We point out that given a sufficiently long sample of the exact short…
Intensified antibunching via feedback-induced quantum interference
Yiping Lu, Nicolas L. Naumann, Javier Cerrillo +3
We numerically show that time delayed coherent feedback controls the statistical output characteristics of driven quantum emitters. Quantum feedback allows to enhance or suppress a…
Driven open quantum systems and Floquet stroboscopic dynamics
Sebastian Restrepo, Javier Cerrillo, Victor Manuel Bastidas +2
We provide an analytic solution to the problem of system-bath dynamics under the effect of high-frequency driving that has applications in a large class of settings, such as driven…
Non-equilibrium quantum transport coefficients and the transient dynamics of full counting statistics in the strong coupling and non-Markovian regimes
Javier Cerrillo, Maximilian Buser, Tobias Brandes
Non-equilibrium transport properties of quantum systems have recently become experimentally accessible in a number of platforms in so-called full-counting experiments that measure…
Efficient simulation of non-Markovian system-environment interaction
Robert Rosenbach, Javier Cerrillo, Susana F. Huelga +2
In this work, we combine an established method for open quantum systems -- the time evolving density matrix using orthogonal polynomials algorithm (TEDOPA) -- with the transfer ten…
Non-Markovian Dynamical Maps: Numerical Processing of Open Quantum Trajectories
Javier Cerrillo, Jianshu Cao
The initial stages of the evolution of an open quantum system encode the key information of its underlying dynamical correlations, which in turn can predict the trajectory at later…
Double-path dark-state laser cooling in a three-level system
Javier Cerrillo, Alex Retzker, Martin B. Plenio
We present a detailed analysis of a robust and fast laser cooling scheme [J. Cerrillo et al.,Phys. Rev. Lett. 104, 043003 (2010)] on a three-level system. A special laser configura…
Pulsed Laser Cooling for Cavity-Optomechanical Resonators
Shai Machnes, Javier Cerrillo, Markus Aspelmeyer +3
A pulsed cooling scheme for optomechanical systems is presented that is capable of cooling at much faster rates, shorter overall cooling times, and for a wider set of experimental…
Robust and optimal laser cooling of trapped ions
J. Cerrillo, A. Retzker, M. B. Plenio
We present a robust and fast laser cooling scheme suitable for trapped atoms and ions. Based on quantum interference, generated by a special laser configuration, it is able to rapi…
