Angle-dependent electron spin resonance of YbRhSi measured with planar microwave resonators and in-situ rotation
Linda Bondorf, Manfred Beutel, Markus Thiemann +6
We present a new experimental approach to investigate the magnetic properties of the anisotropic heavy-fermion system YbRhSi as a function of crystallographic orientation.…
The nature of the Lamb shift in weakly-anharmonic atoms: from normal mode splitting to quantum fluctuations
Mario F. Gely, Gary A. Steele, Daniel Bothner
When a two level system (TLS) is coupled to an electromagnetic resonator, its transition frequency changes in response to the quantum vacuum fluctuations of the electromagnetic fie…
Coupling ultracold atoms to a superconducting coplanar waveguide resonator
H. Hattermann, D. Bothner, L. Y. Ley +6
We demonstrate coupling of magnetically trapped ultracold Rb ground state atoms to a coherently driven superconducting coplanar resonator on an integrated atom chip. We measur…
Improving superconducting resonators in magnetic fields by reduced field-focussing and engineered flux screening
Daniel Bothner, Dominik Wiedmaier, Benedikt Ferdinand +2
We experimentally investigate superconducting coplanar waveguide resonators in external magnetic fields and present two strategies to reduce field-induced dissipation channels and…
Multi-mode ultra-strong coupling in circuit quantum electrodynamics
Sal J. Bosman, Mario F. Gely, Vibhor Singh +3
With the introduction of superconducting circuits into the field of quantum optics, many novel experimental demonstrations of the quantum physics of an artificial atom coupled to a…
Approaching ultra-strong coupling in Transmon circuit-QED using a high-impedance resonator
Sal J. Bosman, Mario F. Gely, Vibhor Singh +3
In this experiment, we couple a superconducting Transmon qubit to a high-impedance microwave resonator. Doing so leads to a large qubit-resonator coupling rate , measur…
Convergence of the multimode quantum Rabi model of circuit quantum electrodynamics
Mario F. Gely, Adrian Parra-Rodriguez, Daniel Bothner +4
Circuit quantum electrodynamics (QED) studies the interaction of artificial atoms, open transmission lines and electromagnetic resonators fabricated from superconducting electronic…
