Speeding Up Squeezing with a Periodically Driven Dicke Model
Jarrod T. Reilly, Simon B. Jäger, John Drew Wilson +3
We present a simple and effective method to create highly entangled spin states on a faster timescale than that of the commonly employed one-axis twisting (OAT) model. We demonstra…
Dissipative Dicke time crystals: an atoms' point of view
Simon B. Jäger, Jan Mathis Giesen, Imke Schneider +1
We develop and study an atom-only description of the Dicke model with time-periodic couplings between atoms and a dissipative cavity mode. The cavity mode is eliminated giving rise…
Coherence Properties of the Repulsive Anyon-Hubbard Dimer
Martin Bonkhoff, Simon B. Jäger, Imke Schneider +2
One-dimensional anyonic models of the Hubbard type show intriguing ground-state properties, effectively transmuting between Bose-Einstein and Fermi-Dirac statistics. The simplest m…
Optimal Generators for Quantum Sensing
Jarrod T. Reilly, John Drew Wilson, Simon B. Jäger +2
We propose a computationally efficient method to derive the unitary evolution that a quantum state is most sensitive to. This allows one to determine the optimal use of an entangle…
Effective description of cooling and thermal shifts in quantum systems coupled to bosonic modes
Simon B. Jäger, Ralf Betzholz
Recently, an effective Lindblad master equation for quantum systems whose dynamics are coupled to dissipative bosonic modes has been introduced [Phys. Rev. Lett. 129, 063601 (2022)…
Measuring the environment of a Cs qubit with dynamical decoupling sequences
Sabrina Burgardt, Simon B. Jäger, Julian Feß +3
We report the experimental implementation of dynamical decoupling on a small, non-interacting ensemble of up to 25 optically trapped, neutral Cs atoms. The qubit consists of the tw…
Study of the long-range transverse field Ising model with fermionic Gaussian states
Michael P. Kaicher, Davide Vodola, Simon B. Jäger
We numerically study the one-dimensional long-range Transverse Field Ising Model (TFIM) in the antiferromagnetic (AFM) regime at zero temperature using Generalized Hartree-Fock (GH…
