Twisted chiral superconductivity in photodoped frustrated Mott insulators
Recent advances in ultrafast pump-probe spectroscopy provide access to hidden phases of correlated matter, including light-induced superconducting states. The theoretical understanding of these nonequilibrium phases remains limited, particularly for correl ...
AMER PHYSICAL SOC2023Linear and nonlinear magnetization dynamics in permalloy thin films grown on DNA origami and nanopatterned permalloy/YIG hybrid structures
Spin waves (SWs) are collective excitations of the spin ensemble in systems with magnetic order. In quantum mechanics, a SW is known as a magnon, which is the quasiparticle describing the quantized nature of these wave-like excitations. Magnonics is the re ...
EPFL2023Small-angle neutron scattering study of mesoscale magnetic disordering and skyrmion phase suppression in the frustrated chiral magnet Co6.75Zn6.75Mn6.51
Henrik Moodysson Rønnow, Jonathan White
Co-Zn-Mn chiral cubic magnets display versatile magnetic skyrmion phases, including equilibrium phases stable far above and far below room temperature, and the facile creation of robust far-from-equilibrium skyrmion states. In this system, compositional di ...
INT UNION CRYSTALLOGRAPHY2022Magnetic structure of the topological semimetal Co3Sn2S2
Henrik Moodysson Rønnow, Ivica Zivkovic, Jian Rui Soh
Co3Sn2S2 has recently been predicted to be a Weyl semimetal in which magnetic order is key to its behavior as a topological material. Here, we report unpolarized neutron diffraction and spherical neutron polarimetry measurements, supported by magnetization ...
AMER PHYSICAL SOC2022Planted XY model: Thermodynamics and inference
Lenka Zdeborová, Guanhao Huang, Giovanni Piccioli, Siyu Chen
In this paper we study a fully connected planted spin glass named the planted XY model. Motivation for studying this system comes both from the spin glass field and the one of statistical inference where it models the angular synchronization problem. We d ...
2022Order parameters for antiferromagnetic structures: A first-principles study of iridium manganese
We use density-functional theory to study the ordered states of iridium manganese, demonstrating a simple but powerful method for describing magnetic structures and the transitions among them. As an illustrative example, the coupling of magnetism and cryst ...
