Floquet solitons and dynamics of periodically driven matter waves with negative effective mass
Matthew Mitchell, Andrea Di Carli, German Sinuco Leon +3
We experimentally study the dynamics of weakly interacting Bose-Einstein condensates of cesium atoms in a 1D optical lattice with a periodic driving force. After a sudden start of…
Using graphene conductors to enhance the functionality of atom-chips
K. Wongcharoenbhorn, R. Crawford, N. Welch +6
We show that the performance and functionality of atom-chips can be transformed by using graphene-based van der Waals heterostructures to overcome present limitations on the lifeti…
Decoherence-free radiofrequency dressed subspaces
G. A. Sinuco-Leon, H. Mas, S. Pandey +3
We study the spectral signatures and coherence properties of radiofrequency dressed hyperfine Zeeman sub-levels of 87Rb. Experimentally, we engineer combinations of static and RF m…
Microwave spectroscopy of radio-frequency dressed Rb
G. A. Sinuco-Leon, B. M. Garraway, H. Mas +8
We study the hyperfine spectrum of atoms of Rb dressed by a radio-frequency field, and present experimental results in three different situations: freely falling atoms, atom…
Atom chips with free-standing two-dimensional electron gases: advantages and challenges
G. A. Sinuco-Leon, Peter Krueger, T. M. Fromhold
In this work we consider the advantages and challenges of using free-standing two-dimensional electron gases (2DEG) as active components in atom chips for manipulating ultracold en…
Inductively guided circuits for ultracold dressed atoms
German Sinuco-Leon, Kathryn Burrows, Aidan S. Arnold +1
We propose a flexible and robust scheme to create closed quasi-one dimensional guides for ultra-cold atoms through the dressing of hyperfine sub-levels of the atomic ground state.…
RF dressed atoms beyond the linear Zeeman effect
G. Sinuco-León, B. M. Garraway
We evaluate the impact that nonlinear Zeeman shifts have on resonant radio-frequency (RF) dressed traps in an atom-chip configuration. The degeneracy of the resonance between Zeema…
Atom chips with two-dimensional electron gases: theory of near surface trapping and ultracold-atom microscopy of quantum electronic systems
G. Sinuco-León, B. Kaczmarek, P. Krüger +1
We show that current in a two-dimensional electron gas (2DEG) can trap ultracold atoms m away with orders of magnitude less spatial noise than a metal trapping wire. This ena…
