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…
Self-sustained optomechanical state destruction triggered by the Kerr nonlinearity
A. Delattre, I. Golokolenov, R. Pedurand +3
Cavity optomechanics implements a unique platform where moving objects can be probed by quantum fields, either laser light or microwave signals. With a pump tone driving at a frequ…
Progress toward detection of individual TLS in nanomechanical resonators
Richard Pedurand, Ilya Golokolenov, Mika Sillanpää +3
The low temperature properties of amorphous solids are usually explained in terms of atomic-scale tunneling two level systems (TLS). For almost 20 years, individual TLS have been p…
Nano-beam clamping revisited
Ilya Golokolenov, Sumit Kumar, Baptiste Alperin +3
Within recent years, the field of nano-mechanics has diversified in a variety of applications, ranging from quantum information processing to biological molecules recognition. Amon…
Thermodynamics of a Single Mesoscopic Phononic Mode
Ilya Golokolenov, Arpit Ranadive, Luca Planat +5
In recent decades, the laws of thermodynamics have been pushed down to smaller and smaller scales, within the field of stochastic thermodynamics and state-of-art experiments perfor…
Fully suspended nano-beams for quantum fluids
Ilya Golokolenov, Baptiste Alperin, Bruno Fernandez +2
Non-invasive probes are keystones of fundamental research. Their size, and maneuverability (in terms of e.g. speed, dissipated power) define their applicability range for a specifi…
Microwave optomechanical measurement of non-metallized SiN strings at mK temperatures
Sumit Kumar, Yannick Klaß, Baptiste Alperin +5
The mechanical properties of amorphous materials (glasses) at low temperatures are dominated by effects of low energy excitations that are thought to be atomic-scale tunneling two…
Microwave single-tone optomechanics in the classical regime
Ilya Golokolenov, Dylan Cattiaux, Sumit Kumar +4
We report on the quantitative experimental illustration of elementary optomechanics within the classical regime. All measurements are performed in a commercial dilution refrigerato…
Nanomechanical damping via electron-assisted relaxation of two-level systems
Olivier Maillet, Dylan Cattiaux, Xin Zhou +4
We report on measurements of dissipation and frequency noise at millikelvin temperatures of nanomechanical devices covered with aluminum. A clear excess damping is observed after s…

We explore the nonlinear dynamics of a cavity optomechanical system. Our realization consisting of a drumhead nano-electro-mechanical resonator (NEMS) coupled to a microwave cavity…
Geometrical Nonlinearity of Circular Plates and Membranes: an Alternative Method
D. Cattiaux, S. Kumar, X. Zhou +2
We apply the well-established theoretical method developed for geometrical nonlinearities of micro/nano-mechanical clamped beams to circular drums. The calculation is performed und…

Advances in nanomechanics within recent years have demonstrated an always expanding range of devices, from top-down structures to appealing bottom-up MoS and graphene membranes…
The Universality of Thermal Transport in Amorphous Nanowires at Low Temperatures
Adib Tavakoli, Christophe Blanc, Hossein Ftouni +4
Thermal transport properties of amorphous materials at low temperatures are governed by the interaction between phonons and localized excitations referred to as tunneling two level…
Elastic measurements of amorphous silicon films at mK temperatures
Andrew Fefferman, Ana Maldonado, Eddy Collin +3
The low temperature properties of glass are distinct from those of crystals due to the presence of poorly understood low-energy excitations. The tunneling model proposes that these…
Classical decoherence in a nanomechanical resonator
Olivier Maillet, Frantisek Vavrek, Andrew D. Fefferman +2
Decoherence is an essential mechanism that defines the boundary between classical and quantum behaviours, while imposing technological bounds for quantum devices. Little is known a…
The thermal conductivity of silicon nitride membranes is not sensitive to stress
