Nonclassical microwave radiation from the parametric dynamical Casimir effect in the reversed-dissipation regime of circuit optomechanics
H. Solki, Ali Motazedifard, M. H. Naderi +2
We propose an experimentally feasible optomechanical system (OMS) that is dispersively driven and operates in the reversed dissipation regime (RDR), where the mechanical damping ra…

Compact superconducting vacuum-gap capacitors with low microwave loss and high mechanical coherence for scalable quantum circuits
Amir Youssefi, Mahdi Chegnizadeh, Marco Scigliuzzo +1
Vacuum-gap capacitors have recently attracted significant interest in superconducting circuit platforms due to their compact design and exceptionally low dielectric losses in the m…

Quantum collective motion of macroscopic mechanical oscillators
Mahdi Chegnizadeh, Marco Scigliuzzo, Amir Youssefi +3
Collective phenomena arise from interactions within complex systems, leading to behaviors absent in individual components. Observing quantum collective phenomena with macroscopic m…
