Synthetic gauge fields for phonon transport in a nano-optomechanical system
John P. Mathew, Javier del Pino, Ewold Verhagen
Gauge fields play important roles in condensed matter, explaining for example nonreciprocal and topological transport phenomena. Establishing gauge potentials for phonon transport…
Tension mediated nonlinear coupling between orthogonal mechanical modes of nanowire resonators
John P. Mathew, Anand Bhushan, Mandar M. Deshmukh
We study the nonlinear coupling between orthogonal flexural modes of doubly clamped InAs nanowire resonators. The two orthogonal modes are formed by the symmetry breaking and lifti…
Optical circulation in a multimode optomechanical resonator
Freek Ruesink, John P. Mathew, Mohammad-Ali Miri +2
Optical circulators are important components of modern day communication technology. With their ability to route photons directionally, these nonreciprocal elements provide useful…
Nanoscale electromechanics to measure thermal conductivity, expansion and interfacial losses
John P. Mathew, Raj Patel, Abhinandan Borah +3
We study the effect of localized Joule heating on the mechanical properties of doubly clamped nanowires under tensile stress. Local heating results in systematic variation of the r…
Dynamical strong coupling and parametric amplification in mechanical modes of graphene drums
John P. Mathew, Raj N. Patel, Abhinandan Borah +2
Mechanical resonators are ubiquitous in modern information technology. With the ability to couple them to electromagnetic and plasmonic modes, they hold the promise to be the key b…
Wide bandwidth nanowire electromechanics on insulating substrates at room temperature
T. S. Abhilash, John P Mathew, Shamashis Sengupta +3
We study InAs nanowire resonators fabricated on sapphire substrate with a local gate configuration. The key advantage of using an insulating sapphire substrate is that it results i…
