Richard L. Greene Dissertation Award recognizes doctoral thesis research of exceptional quality and importance in experimental condensed matter or experimental materials physics. Sean’s excellent dissertation, “Collective excitations in the antisymmetric channel of Raman spectroscopy”, is an outstanding contribution to the physics society.
Multipolar interactions and related ordering phenomena have attracted great interest. Multipoles are related to exotic phases including possible multipole-fluctuation induced superconductivity and hidden-order phase. For a systematic investigation of the collective behaviors of multipole moments, f-electron systems are suitable choices since the interplay of spin and orbital degrees of freedom of f-electrons facilitates multipole formation. …
We are exceptionally proud to announce that Mai Ye has won the Peter Lindenfeld Graduate Fellowship. The fellowship, established to honor Professor Emeritus Lindenfeld, supports a Physics and Astronomy graduate student who exemplifies the teacher-scholar model of learning pioneered by Prof. Lindenfeld. We want to celebrate Mai for his excellence in both scholarship and mentorship!
We are proud to announce that Alex’s poster, “Resonant Raman Scattering in the Giant Rashba System BiTeI“, won the Leszek Wielunski Award for Best Poster Presentation at the 33rd Annual Symposium of the Laboratory for Surface Modification (LSM). Congrats to Alex for winning this prestigious award!
We are proud to announce that Sean Kung’s dissertation, “Collective excitations in the antisymmetric channel of Raman spectroscopy”, is the recipient of the 2019 Northeast Association of Graduate Schools Outstanding Doctoral Dissertation Award. His story is highlighted in the Rutgers Physics News. Congrats to Sean for winning this prestigious award!
We observe composite particles — chiral excitons — residing on the surface of a topological insulator (TI), Bi2Se3. Unlike other known excitons composed of massive quasiparticles, chiral excitons are the bound states of surface massless electrons and surface massive holes, both subject to strong spin–orbit coupling which locks their spins and momenta into chiral textures. …
Long-range order of multipoles, namely high-rank electric or magnetic moments, has been attracting great interest. For example, second-rank quadrupolar moments could lead to novel phenomena including quadrupolar Kondo effect and quadrupole-fluctuation-mediated superconductivity. f-electron systems are suitable choices to study multipolar interactions and ordering phenomena by virtue of the interplay of the spin and orbital degrees …

We are exceptionally proud to announce that our Dr. Hesiang-Hsi (Sean) Kung has been selected to become the Rutgers nominee for the Northeastern Association of Graduate Schools 2019 Doctoral Dissertation Award! His story is highlighted in the School of Graduate Studies (SGS) Grad News.
Authors: W.-L. Zhang, Y. Song, W.-Y. Wang, C.-D. Cao, P.-C. Dai, C.-Q. Jin, and G. Blumberg Abstract: We use polarization-resolved Raman scattering to study lattice dynamics in NaFe0.53Cu0.47As single crystals. We identify four A1g phonon modes, at 126, 172, 183, and 197 cm-1, and four B3g phonon modes at 101, 139, 173, and 226 cm-1(D2h point group). The phonon spectra are consistent …

Authors: M.Ye, H.-S.Kim, J.-W.Kim, C.-J.Won, K.Haule, D.Vanderbilt, S.-W.Cheong and G. Blumberg Abstract: We report ab-initio density functional theory calculation and Raman scattering results to explore the electronic structure of Ba5CuIr3O12 single crystals. This insulating iridate, consisting of face-sharing IrO6 octahedra forming quasi-one-dimensional chains, cannot be described by the local jeff = 1/2 moment picture commonly …
