'Fraternal-twin' ferroelectricity: competing polar states in hydrogen-doped samarium nickelate from first principles
In ferroelectric switching, an applied electric field switches the system between two polar symmetry-equivalent states. In this work, we use first-principles calculations to explore the polar states of hydrogen-doped samarium nickelate (SNO) at a concentra ...
Iop Publishing Ltd2024Polarization-Controlled Chromo-Encryption
Olivier Martin, Hsiang-Chu Wang
The response of simple plasmonic nanorods to polarized illumination is studied in detail. Depending on the orientation of that polarization with respect to the symmetry axes of the nanostructure, a chiral response can occur, which can be analyzed through a ...
WILEY-V C H VERLAG GMBH2023Dynamic nuclear polarisation of 1H in Gd-doped In(OH)3
David Lyndon Emsley, Michael Allan Hope, Yuxuan Zhang, Amrit Venkatesh
Dynamic nuclear polarisation (DNP) of solids doped with high-spin metal ions, such as Gd3+, is a useful strategy to enhance the nuclear magnetic resonance (NMR) sensitivity for these samples. Spin diffusion can relay polarisation throughout a sample, which ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2023Symmetry-Induced Singlet-Triplet Inversions in Non-Alternant Hydrocarbons
Marc Hamilton Folkmann Garner, Anne-Clémence Corminboeuf, Jacob Terence Blaskovits
Molecules with inversion of the singlet and triplet excited-state energies are highly promising for the development of organic light-emitting diodes (OLEDs). To date, azaphenalenes are the only class of molecules where these inversions have been identified ...
2023Quasi-symmetry-protected topology in a semi-metal
Philip Johannes Walter Moll, Matthias Carsten Putzke, Yi-Chiang Sun, Chunyu Guo, Xiangwei Huang, Jonas De Jesus Diaz Gomez
The concept of quasi-symmetry-a perturbatively small deviation from exact symmetry-is introduced and leads to topological materials with strong resilience to perturbations. The crystal symmetry of a material dictates the type of topological band structure ...
NATURE PORTFOLIO2022Geometric Percolation of Spherically Symmetric Fractal Aggregates
The connectedness percolation threshold (phi(c)) for spherically symmetric, randomly distributed fractal aggregates is investigated as a function of the fractal dimension (d(F)) of the aggregates through a mean-field approach. A pair of aggregates (each of ...
SPRINGER2022On the non-existence of stepped-pressure equilibria far from symmetry
The Stepped Pressure Equilibrium Code (SPEC) (Hudson et al 2012 Phys. Plasmas 19 112502) has been successful in the construction of equilibria in 3D configurations that contain a mixture of flux surfaces, islands and chaotic magnetic field lines. In this m ...
2021A note on the large charge expansion in 4d CFT
In this letter, we discuss certain universal predictions of the large charge expansion in conformal field theories with U (1) symmetry, mainly focusing on four-dimensional theories. We show that, while in three dimensions quantum fluctuations are responsib ...
