Transmon in a semi-infinite high-impedance transmission line -- appearance of cavity modes and Rabi oscillations
Emely Wiegand, Benjamin Rousseaux, Göran Johansson
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 la…
Ultrastrong coupling between nanoparticle plasmons and cavity photons at ambient conditions
Denis G. Baranov, Battulga Munkhbat, Elena Zhukova +6
Ultrastrong coupling is a distinct regime of electromagnetic interaction that enables a rich variety of intriguing physical phenomena. Traditionally, this regime has been reached b…
A semiclassical analysis of dark state transient dynamics in waveguide circuit QED
E. Wiegand, B. Rousseaux, G. Johansson
The interaction between superconducting qubits and one-dimensional microwave transmission lines has been studied experimentally and theoretically in the past two decades. In this w…
Non-hermitian Hamiltonian description for quantum plasmonics: from dissipative dressed atom picture to Fano states
H. Varguet, B. Rousseaux, D. Dzsotjan +3
We derive effective Hamiltonians for a single dipolar emitter coupled to a metal nanoparticle (MNP) with particular attention devoted to the role of losses. For small particles siz…
Comparative study of plasmonic antennas for strong coupling and quantum nonlinearities with single emitters
Benjamin Rousseaux, Denis G. Baranov, Mikael Käll +2
Realizing strong coupling between a single quantum emitter (QE) and an optical cavity is of crucial importance in the context of various quantum optical applications. While Rabi sp…
Mode-selective quantization and multimodal effective models for spherically layered systems
D. Dzsotjan, B. Rousseaux, H. R. Jauslin +3
We propose a geometry-specific, mode-selective quantization scheme in coupled field-emitter systems which makes it easy to include material and geometrical properties, intrinsic lo…
