Microscopic dynamics and an effective Landau-Zener transition in the quasi-adiabatic preparation of spatially ordered states of Rydberg excitations
A. F. Tzortzakakis, D. Petrosyan, M. Fleischhauer +1
We examine the adiabatic preparation of spatially-ordered Rydberg excitations of atoms in finite one-dimensional lattices by frequency-chirped laser pulses, as realized in a number…
Cavity Quantum Electrodynamics Effects with Nitrogen Vacancy Center Spins in Diamond and Microwave Resonators at Room Temperature
Yuan Zhang, Qilong Wu, Shi-Lei Su +3
Cavity quantum electrodynamics (C-QED) effects, such as Rabi splitting, Rabi oscillations and superradiance, have been demonstrated with nitrogen vacancy center spins in diamond in…
Quantum batteries at the verge of a phase transition
Felipe Barra, Karen V. Hovhannisyan, Alberto Imparato
Starting from the observation that the reduced state of a system strongly coupled to a bath is, in general, an athermal state, we introduce and study a cyclic battery-charger quant…
Self-Ordering of Individual Photons in Waveguide QED and Rydberg-Atom Arrays
Ole A. Iversen, Thomas Pohl
The scattering between light and individual saturable quantum emitters can induce strong optical nonlinearities and correlations between individual light quanta. Typically, this le…
Fast, high precision dynamics in quantum optimal control theory
Mogens Dalgaard, Felix Motzoi
Quantum optimal control theory is becoming increasingly crucial as quantum devices become more precise, but the need to quickly optimize these systems classically remains a signifi…
Topological phases in interacting spin-1 systems
A. Alnor, T. Bækkegaard, N. T. Zinner
Different topological phases of quantum systems has become areas of increased focus in recent decades. In particular, the question of how to realize and manipulate systems with non…
Strong laser fields and their power to generate controllable high-photon-number coherent-state superpositions
Javier Rivera-Dean, Theocharis Lamprou, Emilio Pisanty +5
Recently, intensely driven laser-matter interactions have been used to connect the fields of strong laser field physics with quantum optics by generating non-classical states of li…
Reinforcement Learning vs. Gradient-Based Optimisation for Robust Energy Landscape Control of Spin-1/2 Quantum Networks
I. Khalid, C. A. Weidner, E. A. Jonckheere +2
We explore the use of policy gradient methods in reinforcement learning for quantum control via energy landscape shaping of XX-Heisenberg spin chains in a model agnostic fashion. T…
Free-Fermion Multiply Excited Eigenstates and Their Experimental Signatures in 1D Arrays of Two-Level Atoms
Yu-Xiang Zhang, Klaus Mølmer
One-dimensional (1D) subwavelength atom arrays display multiply excited subradiant eigenstates which are reminiscent of free fermions. So far, these states have been associated wit…
Open Quantum Rotors: Connecting Correlations and Physical Currents
Ricardo Puebla, Alberto Imparato, Alessio Belenchia +1
We consider a finite one-dimensional chain of quantum rotors interacting with a set of thermal baths at different temperatures. When the interaction between the rotors is made chir…
Quantum Wheatstone Bridge
Kasper Poulsen, Alan C. Santos, Nikolaj T. Zinner
We propose a quantum Wheatstone bridge as a fully quantum analogue to the classical version. The bridge is a few-body boundary-driven spin chain exploiting quantum effects to gain…
Quantum Maxwell's Demon Assisted by Non-Markovian Effects
Kasper Poulsen, Marco Majland, Seth Lloyd +2
Maxwell's demon is the quintessential example of information control, which is necessary for designing quantum devices. In thermodynamics, the demon is an intelligent being who uti…
A quantum fluctuation theorem for any Lindblad master equation
Gabriele De Chiara, Alberto Imparato
We present a general quantum fluctuation theorem for the entropy production of an open quantum system coupled to multiple environments, not necessarily at equilibrium. Such a gener…
Dynamical uncertainty propagation with noisy quantum parameters
Mogens Dalgaard, Carrie A. Weidner, Felix Motzoi
Many quantum technologies rely on high-precision dynamics, which raises the question of how these are influenced by the experimental uncertainties that are always present in real-l…
Predicting quantum dynamical cost landscapes with deep learning
Mogens Dalgaard, Felix Motzoi, Jacob Sherson
State-of-the-art quantum algorithms routinely tune dynamically parametrized cost functionals for combinatorics, machine learning, equation-solving, or energy minimization. However,…

Lars Bojer Madsen
The strong-field approximation for high-harmonic generation in near-infrared and infrared laser pulses is formulated in the accelerated Kramers-Henneberger frame. The accompanying…
Active Frequency Measurement on Superradiant Strontium Clock Transitions
Yuan Zhang, Chongxin Shan, Klaus Mølmer
We develop a stochastic mean-field theory to describe active frequency measurements of pulsed superradiant emission, studied in recent experiments with strontium-87 atoms trapped i…
Efimov effect evaporation after confinement
E. Garrido, A. S. Jensen
The continuous confinement of quantum systems can be described by means of the -method, where the dimension is taken as a continuous parameter. In this work we describe in d…
Time periodicity from randomness in quantum systems
Giacomo Guarnieri, Mark T. Mitchison, Archak Purkayastha +3
Many complex systems can spontaneously oscillate under non-periodic forcing. Such self-oscillators are commonplace in biological and technological assemblies where temporal periodi…
Energy conservation and fluctuation theorem are incompatible for quantum work
Karen V. Hovhannisyan, Alberto Imparato
Characterizing fluctuations of work in coherent quantum systems is notoriously problematic. Here we reveal the ultimate source of the problem by proving that () energ…
How well can we guess the outcome of measurements of non-commuting observables?
Maryam Khanahmadi, Klaus Mølmer
According to Heisenberg's uncertainty relation, there is an ultimate limit to how precisely we may predict the outcome of position and momentum measurements on a quantum system. We…
