Move aside, electrons; it's time to make way for the trion.

Analogous to the unique spectral fingerprint of any atom or molecule, researchers have measured the spectrum of optical excitations in monolayer tungsten diselenide (WSe2), which is a member of a new family of ultrathin semiconductors that are just one atomic layer thick.

Scientists discovered how to tune the optical properties of atomically-thin semiconductors, which will aid the design of future microscopic light sensors.

With a sufficiently high magnetic field, scientists can manipulate certain phase transitions in some molecules, a discovery that hints at future technological applications.

A scientist combines high magnetic fields with ultra short laser pulses to probe the mysteries of photosynthesis.

Giti Khodaparast.Giti Khodaparast.Giti Khodaparast, a Virginia Tech physicist who has conducted experiments at the National MagLab using magneto-optics measurement techniques, has been recognized by the American Physical Society as its Woman Physicist of the Month for March 2016. Khodaparast was lauded for research using magneto-optical spectroscopy, her international and interdisciplinary collaboration and the development of modern experimental techniques. She was also recognized for training young scientists through mentorship and curriculum development and for advancing women in the field of physics.

Scientists begin to fill in the blanks on transition metal dichalcogenides.

Utilizing the sensitivity of the NHMFL optics facility, a team of scientists from Georgia Tech, Sandia National Laboratories, Institut Néel, Université Paris-Sud and the NHMFL were able to observe collective oscillations of Dirac Fermions in graphene nanoribbons. The observed effect is tunable by varying the width of the graphene nanoribbons and the applied magnetic field. This observation raises the possibility of graphene based tunable THz devices.

This magnet is dedicated for optics research. SCM3 is a cold bore system capable of measurements from 4 K to 300 K.

Superfluorescence, historically, is the spontaneous emission of light from a collection of excited atoms. Scientists visiting the MagLab recently discovered superfluorescence for the first time in a solid material, by shining an extremely brief pulse of light on a layered semiconductor located in an intense magnetic field. In response, superfluorescent light of a different color was emitted thirty trillionths of a second later. Superfluorescence can be used to produce light of any desired color and could be enhanced to occur at room temperature and without magnetic fields. Superfluorescent devices would be powerful tools for optical communications.
