Simulating moving cavities in superconducting circuits
Stefano Bosco, Joel Lindkvist, Göran Johansson
We theoretically investigate the simulation of moving cavities in a superconducting circuit setup. In particular, we consider a recently proposed experimental scenario where the ph…
Dynamical response of Bose-Einstein condensates to oscillating gravitational fields
Dennis Rätzel, Richard Howl, Joel Lindkvist +1
A description of the dynamical response of uniformly trapped Bose-Einstein condensates (BECs) to oscillating external gravitational fields is developed, with the inclusion of dampi…
Motion and gravity effects in the precision of quantum clocks
Joel Lindkvist, Carlos Sabín, Göran Johansson +1
We show that motion and gravity affect the precision of quantum clocks. We consider a localised quantum field as a fundamental model of a quantum clock moving in spacetime and show…
Scattering of coherent pulses on a two-level system - single-photon generation
Joel Lindkvist, Göran Johansson
In this work, we consider a two-level system (TLS) coupled to a one-dimensional continuum of bosonic modes in a transmission line. Using the master equation approach, a method for…
Twin paradox with macroscopic clocks in superconducting circuits
Joel Lindkvist, Carlos Sabín, Ivette Fuentes +4
We propose an implementation of a twin paradox scenario in superconducting circuits, with velocities as large as a few percent of the speed of light. Ultrafast modulation of the bo…
Microwave Quantum Optics with an Artificial Atom
Io-Chun Hoi, C. M. Wilson, Göran Johansson +4
We address the recent advances on microwave quantum optics with artificial atoms. This field relies on the fact that the coupling between a superconducting artificial atom and prop…
Scattering of coherent states on a single artificial atom
B. Peropadre, J. Lindkvist, I. -C. Hoi +4
In this work we theoretically analyze a circuit QED design where propagating quantum microwaves interact with a single artificial atom, a single Cooper pair box. In particular, we…
Generation of nonclassical microwave states using an artificial atom in 1D open space
Io-Chun Hoi, Tauno Palomaki, Göran Johansson +3
We have embedded an artificial atom, a superconducting transmon qubit, in a 1D open space and investigated the scattering properties of an incident microwave coherent state. By stu…
