• #### Macroscopic Ensembles of Aligned Carbon Nanotubes in Bubble Imprints Studied by Polarized Raman Microscopy ﻿

(2014)
We study the alignment of single-wall carbon nanotubes (SWCNTs) in bubble imprints through polarized Raman microscopy. A hemispherical bubble containing SWCNTs is pressed against a glass substrate, resulting in an imprint ...
• #### Magnesium Fluctuations Modulate RNA Dynamics in the SAM-I Riboswitch ﻿

(2012)
Experiments demonstrate that Mg2+ is crucial for structure and function of RNA systems, yet the detailed molecular mechanism of Mg2+ action on RNA is not well understood. We investigate the interplay between RNA and Mg2+ ...
• #### Magnetic and Ising quantum phase transitions in a model for isoelectronically tuned iron pnictides ﻿

(2016)
Considerations of the observed bad-metal behavior in Fe-based superconductors led to an early proposal for quantum criticality induced by isoelectronic P for As doping in iron arsenides, which has since been experimentally ...

We present high spectral resolution (R ≈ 108,000) Stokes V polarimetry of the classical T Tauri stars (CTTSs) GQ Lup and TW Hya obtained with the polarimetric upgrade to the HARPS spectrometer on the ESO 3.6 m telescope. ...
• #### Magnetism, chemical spots, and stratification in the HgMn star ϕ Phoenicis ﻿

(2012)
Context. Mercury-manganese (HgMn) stars have been considered as non-magnetic and non-variable chemically peculiar (CP) stars for a long time. However, recent discoveries of the variability in spectral line profiles have ...
