Damping-dependent 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…
Noncontact friction in ultracoherent nanomechanical resonators near dielectric materials
Amirali Arabmoheghi, Alessio Zicoschi, Guillermo Arregui +4
Micro- and nanomechanical resonators are emerging as promising platforms for quantum technologies, precision sensors and fundamental science experiments. To utilize these devices f…
Realization of tilted Dirac-like microwave cone in superconducting circuit lattices
Amir Youssefi, Ahmad Motavassal, Shingo Kono +2
Dirac-like band crossings are paradigms in condensed matter systems to emulate high-energy physics phenomena. They are associated with two aspects: gap and tilting. The ability to…
Dissipation engineering of high-stress silicon nitride nanobeams
A. H. Ghadimi, D. J. Wilson, T. J. Kippenberg
High-stress SiN nanoresonators have become an attractive choice for electro- and optomechanical devices. Membrane resonators can achieve quality factor () - frequency ($…
