Pressure-Dependent Polymorphism and Band-Gap Tuning of Methylammonium Lead Iodide Perovskite by Jiang, Shaojie, Fang, Yanan, Li, Ruipeng, Xiao, Hai, Crowley, Jason, Wang, Chenyu, White, Timothy John, Goddard III, William A., Wang, Zhongwu, Baikie, Tom, Fang, Jiye

Published 2017

“…We report the pressure-induced crystallographic transitions and optical behavior of MAPbI3 (MA=methylammonium) using in situ synchrotron X-ray diffraction and laser-excited photoluminescence spectroscopy, supported by density functional theory (DFT) calculations using the hybrid functional B3PW91 with spin-orbit coupling. The tetragonal polymorph determined at ambient pressure transforms to a ReO3-type cubic phase at 0.3 GPa. …”

Bondi mass with a cosmological constant by Saw, Vee-Liem

Published 2018

“…Furthermore, with MΛ=MB, we show that for purely quadrupole gravitational waves given off by the isolated system (i.e., when the “Bondi news” σo comprises only the l=2 components of the spherical harmonics with spin-weight 2) the energy carried away is manifestly positive definite for the Λ>0 case. …”

Non-Abelian adiabatic geometric transformations in a cold strontium gas by Leroux, Frederic, Miniatura, Christian, Grémaud, Benoît, Wilkowski, David, Rebhi, Riadh, Pandey, K., Chevy, F.

Published 2018

“…Topology, geometry, and gauge fields play key roles in quantum physics as exemplified by fundamental phenomena such as the Aharonov–Bohm effect, the integer quantum Hall effect, the spin Hall, and topological insulators. The concept of topological protection has also become a salient ingredient in many schemes for quantum information processing and fault-tolerant quantum computation. …”

Electric field modulation of the tetragonal domain orientation revealed in the magnetic ground state of quantum paraelectric EuTiO3 by Kato, Y., Sunku, S. S., Ito, T., Spalek, L., Shimuta, M., Katsufuji, T., Saxena, S. S., Batista, Cristian D., Petrovic, A. P., Sengupta, Pinaki, Panagopoulos, Christos

Published 2013

“…Our experimentally determined magnetic phase diagram is accurately reproduced by a three-dimensional (3D) anisotropic Heisenberg spin model. Furthermore, we demonstrate that electric field cooling acts to suppress this orientational disorder by realigning the domains due to the strong coupling between electric fields and lattice dipoles characteristic of paraelectric materials.…”
