Nonlinear nanomechanical resonators approaching the quantum ground state
C. Samanta, S. L. De Bonis, C. B. Møller +9
An open question in mechanics is whether mechanical resonators can be made nonlinear with vibrations approaching the quantum ground state. This requires engineering a mechanical no…
On-chip picosecond synchrotron pulse shaper
Jian Zhou, Jinxing Jiang, Donald A. Walko +4
Synchrotrons are powerful and productive in revealing the spatiotemporal complexities in matter. However, X-ray pulses produced by the synchrotrons are predetermined in specific pa…
Nanomechanical vibrational response from electrical mixing measurements
C. Samanta, D. A. Czaplewski, S. L. De Bonis +6
Driven nanomechanical resonators based on low-dimensional materials are routinely and efficiently detected with electrical mixing measurements. However, the measured signal is a no…
The effect of periodic spatial perturbations on the emission rates of quantum dots near graphene platforms
X. Miao, D. J. Gosztola, X. Ma +3
Quenching of fluorescence (FL) at the vicinity of conductive surfaces, and in particular, near a 2-D graphene layer has become an important biochemical sensing tool. The quenching…
Three-dimensional phonon population anisotropy in silicon nanomembranes
Kyle M. McElhinny, Gokul Gopalakrishnan, Martin V. Holt +2
Nanoscale single-crystals possess modified phonon dispersions due to the truncation of the crystal. The introduction of surfaces alters the population of phonons relative to the bu…
Width-dependent Photoluminescence and Anisotropic Raman Spectroscopy from Monolayer MoS Nanoribbons
Guohua Wei, Erik J. Lenferink, David A. Czaplewski +1
Single layers of transition metal dichalcogenides such as MoS are direct bandgap semiconductors with optical and electronic properties distinct from multilayers due to strong v…
Realization of a system with metastable states of a capacitively-shunted fluxonium
Nathan Earnest, Srivatsan Chakram, Yao Lu +9
We realize a system in a superconducting circuit, with metastable states exhibiting lifetimes up to 8\,ms. We exponentially suppress the tunneling matrix elements involved in s…
Self-sustained micromechanical oscillator with linear feedback
Changyao Chen, Damián H. Zanette, Jeffrey R. Guest +2
Autonomous oscillators, such as clocks and lasers, produce periodic signals \emph{without} any external frequency reference. In order to sustain stable periodic motions, there need…
Direct observation of coherent energy transfer in nonlinear micro-mechanical oscillators
Changyao Chen, Damián H. Zanette, David Czaplewski +2
Energy dissipation is an unavoidable phenomenon of physical systems that are directly coupled to an external environmental bath. The ability to engineer the processes responsible f…
Valley Polarization in Size-Tunable Monolayer Semiconductor Quantum Dots
Guohua Wei, David A. Czaplewski, Erik J. Lenferink +3
Three-dimensional confinement allows semiconductor quantum dots (QDs) to exhibit size-tunable electronic and optical properties that enable a wide range of opto-electronic applicat…
Coupling an ensemble of electrons on superfluid helium to a superconducting circuit
Ge Yang, A. Fragner, G. Koolstra +4
The quantized lateral motional states and the spin states of electrons trapped on the surface of superfluid helium have been proposed as basic building blocks of a scalable quantum…
Diffraction limited focusing and routing of gap plasmons by a metal-dielectric-metal lens
