• Title: Transmon in a semi-infinite high-impedance transmission line -- appearance of cavity modes and Rabi oscillations
• Authors: Emely Wiegand, Benjamin Rousseaux and G\"oran Johansson
• Abstract summary: In this letter, we investigate the dynamics of a single superconducting artificial atom capacitively coupled to a transmission line. Adding a single mirror in the transmission line then creates cavity modes between the atom and the mirror. Investigating the spontaneous emission from the atom, we then find Rabi oscillations, where the energy oscillates between the atom and one of the cavity modes.

• Abstract: In this letter, we investigate the dynamics of a single superconducting artificial atom capacitively coupled to a transmission line with a characteristic impedance comparable or larger than the quantum resistance. In this regime, microwaves are reflected from the atom also at frequencies far from the atom's transition frequency. Adding a single mirror in the transmission line then creates cavity modes between the atom and the mirror. Investigating the spontaneous emission from the atom, we then find Rabi oscillations, where the energy oscillates between the atom and one of the cavity modes.

  We investigate the amplification of a microwave probe signal by a superconducting artificial atom. Due to the weak anharmonicity of the artificial atom, a strong pump field creates excitations among the dressed states. We obtain a maximum amplitude of about 18 %, higher than in any previous experiment with a single artificial atom.

  We consider the cooperative spontaneous emission of a system of two identical atoms, interacting with the electromagnetic field in the vacuum state.

We show that it is modulated in time, and that the presence of the oscillating mirror can enhance or inhibit the decay rate.
