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.

“…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

“…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.…”

Induction of z-conformation in ribosomal RNA by Z-DNA binding domain Zα of the human double-stranded RNA deaminase I (ADAR1) by Zhao, Jing
