From chessboard of bipolarons of size 4a in cubic La7/8Sr1/8MnO3 to stripes of the same bipolarons in layered high Tc cuprates
Martine Hennion, Alexandre Ivanov, Claudine Lacroix +1
The compound La1-xSrxMnO3 exhibits a charge order (CO) state at and , which recalls the CO state with a decrease in the temperature of the superconducting…
Thermodynamical study of N clathrate hydrate from DFT calculations
L. Martin-Gondre, V. Meko Fotso, C. Métais +3
Thermodynamic stability of N clathrate hydrates in the sI and sII structures is investigated using density functional theory with several exchange-correlation functionals, expl…
Altermagnetism revealed by polarized neutrons in MnF
Quentin Faure, Dalila Bounoua, Victor Balédent +6
Motivated by possible spintronics applications in antiferromagnets, it was recently observed that symmetry admits magnets that combine attractive features of both ferromagnets and…
Hollow Lattice Tensor Gauge Theories with Bosonic Matter
José M. Cruz, Masafumi Udagawa, Pedro Bicudo +2
Higher rank gauge theories are generalizations of electromagnetism where, in addition to overall charge conservation, there is also conservation of higher rank multipoles such as t…
Spin liquid state in a three-dimensional pyrochlore-like frustrated magnet
U. Jena, S. Kundu, Suheon Lee +7
The three-dimensional frustrated spin lattice in MgCrGaO4, where Cr3+ ions occupy a pyrochlore-like network, exemplifies a quantum magnet with competing interactions, macroscopic d…
Geometrically Frustrated Quadrupoles on the Pyrochlore Lattice and Generalized Spin Liquids
Kristian Tyn Kai Chung, Sylvain Petit, Julien Robert +1
As an instance of geometrical frustration with non-magnetic degrees of freedom, we explore the physics of local spin moments on the pyrochlore lattice that interact via p…
