Observation of density-dependent gauge fields in a Bose-Einstein condensate based on micromotion control in a shaken two-dimensional lattice
Logan W. Clark, Brandon M. Anderson, Lei Feng +3
We demonstrate a density-dependent gauge field, induced by atomic interactions, for quantum gases. The gauge field results from the synchronous coupling between the interactions an…
Dynamics and interactions of particles in a thermophoretic trap
Benjamin Foster, Frankie Fung, Connor Fieweger +4
We investigate dynamics and interactions of particles levitated and trapped by the thermophoretic force in a vacuum cell. Our analysis is based on footage taken by orthogonal camer…
Collective emission of matter-wave jets from driven Bose-Einstein condensates
Logan W. Clark, Anita Gaj, Lei Feng +1
Scattering is an elementary probe for matter and its interactions in all areas of physics. Ultracold atomic gases provide a powerful platform in which control over pair-wise intera…
Coherent inflationary dynamics for Bose-Einstein condensates crossing a quantum critical point
Lei Feng, Logan W. Clark, Anita Gaj +1
Quantum phase transitions, transitions between many-body ground states, are of extensive interest in research ranging from condensed matter physics to cosmology. Key features of th…
Condensate losses and oscillations induced by Rydberg atoms
Tomasz Karpiuk, Mirosław Brewczyk, Kazimierz Rzążewski +5
We numerically analyze the impact of a single Rydberg electron onto a Bose-Einstein condensate. Both and Rydberg states are studied. The radial size of and state…
Controlling Rydberg atom excitations in dense background gases
Tara Cubel Liebisch, Michael Schlagmüller, Felix Engel +13
We discuss the density shift and broadening of Rydberg spectra measured in cold, dense atom clouds in the context of Rydberg atom spectroscopy done at room temperature, dating back…
Ultracold chemical reactions of a single Rydberg atom in a dense gas
Michael Schlagmüller, Tara Cubel Liebisch, Felix Engel +10
Within a dense environment (atoms/cm) at ultracold temperatures (), a single atom excited to a Rydberg state acts as a reaction center for…
Observation of mixed singlet-triplet Rb Rydberg molecules
Fabian Böttcher, Anita Gaj, Karl M. Westphal +6
We present high-resolution spectroscopy of Rb ultralong-range Rydberg molecules bound by mixed singlet-triplet electron-neutral atom scattering. The mixing of the scatte…
Hybridization of Rydberg electron orbitals by molecule formation
A. Gaj, A. T. Krupp, P. Ilzhöfer +3
The formation of ultralong-range Rydberg molecules is a result of the attractive interaction between Rydberg electron and polarizable ground state atom in an ultracold gas. In the…
Ultracold atom-electron interaction: from two to many-body physics
Anita Gaj, Alexander T. Krupp, Jonathan B. Balewski +3
The transition from a few-body system to a many-body system can result in new length scales, novel collective phenomena or even in a phase transition. Such a threshold behavior was…
Imaging single Rydberg electrons in a Bose-Einstein condensate
Tomasz Karpiuk, Mirosław Brewczyk, Kazimierz Rzążewski +7
The quantum mechanical states of electrons in atoms and molecules are distinct orbitals, which are fundamental for our understanding of atoms, molecules and solids. Electronic orbi…
Alignment of D-state Rydberg molecules
Alexander T. Krupp, Anita Gaj, Jonathan B. Balewski +6
We report on the formation of ultralong-range Rydberg D-state molecules via photoassociation in an ultracold cloud of rubidium atoms. By applying a magnetic offset field on the ord…
Rydberg dressing: Understanding of collective many-body effects and implications for experiments
Jonathan B. Balewski, Alexander T. Krupp, Anita Gaj +3
The strong interaction between Rydberg atoms can be used to control the strength and character of the interatomic interaction in ultracold gases by weakly dressing the atoms with a…
Coupling a single electron to a Bose-Einstein condensate
Jonathan B. Balewski, Alexander T. Krupp, Anita Gaj +5
The coupling of electrons to matter is at the heart of our understanding of material properties such as electrical conductivity. One of the most intriguing effects is that electron…
