A dual-trap system for the study of charged rotating graphene nanoplatelets in high vacuum
Joyce E. Coppock, Pavel Nagornykh, Jacob P. J. Murphy +3
We discuss the design and implementation of a system for generating charged multilayer graphene nanoplatelets and introducing a nanoplatelet into a quadrupole ion trap in high vacu…
Optical and magnetic measurements of gyroscopically stabilized graphene nanoplatelets levitated in an ion trap
Pavel Nagornykh, Joyce E. Coppock, Jacob P. J. Murphy +1
Using optical measurements, we demonstrate that the rotation of micron-scale graphene nanoplatelets levitated in a quadrupole ion trap in high vacuum can be frequency locked to an…
Cooling of Levitated Graphene Nanoplatelets in High Vacuum
Pavel Nagornykh, Joyce E. Coppock, B. E. Kane
We demonstrate cooling of the center of mass motion of charged graphene nanoplatelets levitated in a quadrupole ion trap in high vacuum down to temperatures of 20 K. Parametric fee…
Frequency and temperature dependence of the anomalous Hall conductivity in a chiral px+ipy superconductor with impurities
Roman M. Lutchyn, Pavel Nagornykh, Victor M. Yakovenko
We calculate frequency and temperature dependence of the anomalous ac Hall conductivity induced by impurity scattering in a chiral px+ipy superconductor, such as Sr2RuO4, with spon…
Gauge-invariant electromagnetic response of a chiral px+ipy superconductor
Roman M. Lutchyn, Pavel Nagornykh, Victor M. Yakovenko
We present a gauge-invariant theory of the electromagnetic response of a chiral px+ipy superconductor in the clean limit. Due to the spontaneously broken time-reversal symmetry, th…
Expansion of a mesoscopic Fermi system from a harmonic trap
Pavel Nagornykh, Victor Galitski
We study quantum dynamics of an atomic Fermi system with a finite number of particles, N, after it is released from a harmonic trapping potential. We consider two different initial…
