Tunable Fano Resonance and Frequency Locking in a Graphene-SiNx Hybrid Nanomechanical Resonator
Ateesh K. Rathi, Javed A. Mondal, Rajan Singh +3
Fano resonances, arising from the interference between discrete and continuum states, are observed across a wide range of quantum and classical systems. Here, we report the experim…
Tunable Nonlinear Landscapes in Graphene Nanoelectromechanical Systems
Ateesh K. Rathi, Rajan Singh, Javed A. Mondal +4
Nonlinear nanomechanical resonators give convenient solid-state access to classical analogs of extreme nonlinear optics and to phononic signal processing. Here we report integer hi…
Observation of tunable discrete time crystalline phases
Arnab Sarkar, Anurag, Javed A. Mondal +7
Discrete time crystals (DTCs) are emergent non-equilibrium phases of periodically driven many-body systems, with potential applications ranging from quantum computing to sensing an…
Giant Tunable Mechanical Nonlinearity in Graphene-Silicon Nitride Hybrid Resonator
Rajan Singh, Arnab Sarkar, Chitres Guria +4
High quality factor mechanical resonators have shown great promise in developing classical or quantum technologies. Simultaneously, progress has been made in developing controlled…
Motion transduction with thermo-mechanically squeezed graphene resonator modes
Rajan Singh, Ryan J. T. Nicholl, Kirill Bolotin +1
There is a recent surge of interest in amplification and detection of tiny motion in the growing field of opto and electro mechanics. Here, we demonstrate widely tunable, broad ban…
Hidden area and mechanical nonlinearities in freestanding graphene
Ryan J. T. Nicholl, Nickolay V. Lavrik, Ivan Vlassiouk +2
We investigated the effect of out-of-plane crumpling on the mechanical response of graphene membranes. In our experiments, stress was applied to graphene membranes using pressurize…
The Effect of Intrinsic Crumpling on the Mechanics of Free-Standing Graphene
Ryan J. T. Nicholl, Hiram J. Conley, Nickolay V. Lavrik +5
Free-standing graphene is inherently crumpled in the out-of-plane direction due to dynamic flexural phonons and static wrinkling. We explore the consequences of this crumpling on t…
