Floquet-heating-induced Bose condensation in a scarlike mode of an open driven optical-lattice system

A Schnell, LN Wu, A Widera, A Eckardt - Physical Review A, 2023 - APS
The combination of driving and dissipation guides a quantum system into a nonequilibrium
steady state (NESS). It is an intriguing question, in how far this principle can be exploited for …

Dissipative preparation of a Floquet topological insulator in an optical lattice via bath engineering

A Schnell, C Weitenberg, A Eckardt - SciPost Physics, 2024 - scipost.org
Floquet engineering is an important tool for realizing topologically nontrivial band structures
for charge-neutral atoms in optical lattices. However, the preparation of a topological-band …

In situ observation of chemistry in Rydberg molecules within a Bose-Einstein-condensate

F Engel, SK Tiwari, T Pfau, S Wüster, F Meinert - Physical Review Research, 2024 - APS
We often infer the state of systems in nature indirectly, for example, in high-energy physics
by the interaction of particles with an ambient medium. We adapt this principle to energies 9 …

In situ observation of chemistry in Rydberg molecules within a coherent solvent

F Engel, SK Tiwari, T Pfau, S Wüster… - arXiv preprint arXiv …, 2023 - arxiv.org
We often infer the state of systems in nature indirectly, for example in high energy physics by
recording the tracks particles leave behind in an ambient medium. We adapt this principle to …

Imaging the interface of a qubit and its quantum-many-body environment

S Rammohan, S Tiwari, A Mishra, A Pendse… - Physical Review A, 2021 - APS
Decoherence affects all quantum systems, natural or artificial, and is the primary obstacle
impeding quantum technologies. We show theoretically that for a Rydberg qubit in a Bose …

Micro–micro and micro–macro entanglement witnessing via the geometric phase in an impurity-doped Bose–Einstein condensate

We propose a theoretical proposal to witness micro–micro and micro–macro entanglement
in terms of the geometric phase based on a micro–macro hybrid quantum system, the …

Einstein-Podolsky-Rosen steering of quantum phases in a cavity Bose-Einstein condensate with a single impurity

SP Jia, B Li, YF Jiao, H Jing, LM Kuang - arXiv preprint arXiv:2205.13938, 2022 - arxiv.org
We study Einstein-Podolsky-Rosen (EPR) steering properties of quantum phases in the
generalized Dicke model (GDM) generated by a cavity Bose-Einstein condensate (BEC) …

Dynamics of atoms within atoms

Abstract Recent experiments with Bose–Einstein condensates have entered a regime in
which thousands of ground-state condensate atoms fill the Rydberg-electron orbit. After the …

Collective Excitations of Bose–Einstein Condensate in a Rydberg Atom

A Banerjee, D Majumder - Journal of Low Temperature Physics, 2024 - Springer
In this work, we investigated a Bose–Einstein condensate (BEC) inside a Rydberg atom. We
first observed the system's density profile using the Gross–Pitaevskii equation, and then we …
