Space-resolved Chemical Information from Infrared Extinction Spectra
Kalpa de Silva, Proity Akbar, Reinhold Blümel
Based on the classical Lorentz model of the index of refraction, a new method is presented for the extraction of the complex index of refraction from the extinction efficiency of h…
Measurement of charge-exchange between Na and \ce{Ca+} in a hybrid trap
J. M. Kwolek, D. S. Goodman, B. Slayton +4
We present measurements of the charge-exchange reaction rate between neutral sodium (Na) and ionized calcium (\ce{Ca+}) in a hybrid atom-ion trap, which is comprised of a Na magnet…
Loading a linear Paul trap to saturation from a magneto-optical trap
J. E. Wells, R. Blümel, J. M. Kwolek +2
We present experimental measurements of the steady-state ion number in a linear Paul trap (LPT) as a function of the ion-loading rate. These measurements, taken with (a) constant P…
Infrared refractive index dispersion of PMMA spheres from synchrotron extinction spectra
R. Blümel, M. Bağcıoğlu, R. Lukacs +1
We performed high-resolution Fourier-transform infrared (FTIR) spectroscopy of a polymethyl methacrylate (PMMA) sphere of unknown size in the Mie scattering region. Apart from a sl…
Critical exponents for the cloud-crystal phase transition of charged particles in a Paul Trap
D. K. Weiss, Y. S. Nam, R. Blümel
It is well known that charged particles stored in a Paul trap, one of the most versatile tools in atomic and molecular physics, may undergo a phase transition from a disordered clo…
Conceptually new mechanism for trapping neutral, polar particles
R. Blümel
It is shown that a superposition of static and rapidly oscillating electric {\it monopole} (source) fields is capable of trapping particles with a permanent electric dipole moment.…
