Thermalization of neighboring nanomechanical resonators below 1 mK
Amir Youssefi, Mahdi Chegnizadeh, Francis Bettsworth +4
The position noise spectra of six drums on a single chip were measured on a single cooldown below 1.3 kelvin. Cryostat temperatures as low as 0.7 mK were achieved. The temperature…

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…
