Quantum theory of structured monochromatic light
Alexander Punnoose, Jiufeng J. Tu
Applications that envisage utilizing the orbital angular momentum (OAM) at the single photon level assume that the OAM degrees of freedom that the photons inherit from the classica…
A broadband silicon quarter-wave retarder for far-infrared spectroscopic circular dichroism
Xiaoxiang Xi, R. J. Smith, T. N. Stanislavchuk +4
The high brightness, broad spectral coverage and pulsed characteristics of infrared synchrotron radiation enable time-resolved spectroscopy under throughput-limited optical systems…
Decomposition of direct product at an arbitrary Brillouin zone point:
Jian Li, Jiufeng J. Tu, Joseph L. Birman
A general rule is presented for the decomposition of the direct product of irreducible representation at arbitrary Brillouin zone point with its negative: the number of th…
One dimensional zone center phonons in space group
Jian Li, Jiufeng J. Tu, Joseph L. Birman
Motivated by experiments, we performed a systematic study on the one dimensional zone center phonons in space groups. All the one dimensional phonon modes for different Wyc…
Optical selection rules in topological insulators BiSb, BiSe, BiTe and SbTe
Jian Li, Jiufeng J. Tu, Joseph L. Birman
We performed group theoretical investigation of symmetries of excitations in topological insulators \ce{Bi2Sb3}, \ce{Bi2Te3}, \ce{Bi2Se3} and \ce{Sb2Te3}, focusing on selection rul…
Local Structure of Thermoelectric Ca3Co4O9
T. A. Tyson, Z. Chen, Q. Jie +2
We have combined temperature dependent local structural measurements with first principles density functional calculations to develop a three dimensional local structure model of t…
