Magnetism of Single Surface Adsorbed Atoms Studied with Radio-Frequency STM
This thesis investigates the magnetic properties of single atoms and molecules adsorbed on thin magnesium oxide decoupling layers, grown on a silver single crystal. To address these systems experimentally, we use a low temperature scanning tunneling micros ...
EPFL2024Possible restoration of particle-hole symmetry in the 5/2-quantized Hall state at small magnetic field
Frédéric Mila, Loïc Jean Pierre Herviou
Motivated by the experimental observation of a quantized 5/2 thermal conductance at filling nu = 5/2, a result incompatible with both the Pfaffian and the anti-Pfaffian states, we have pushed the expansion of the effective Hamiltonian of the 5/2-quantized ...
AMER PHYSICAL SOC2023Spin Textures in 2D Magnets
The continuous reduction of the structural size in nanotechnology slowed down over the last decade, approaching the natural limit of single atoms as building blocks of matter. Therefore, intensive research is directed toward exploring new frontiers, in par ...
EPFL2023Intercalant-mediated Kitaev exchange in Ag3LiIr2O6
The recently synthesized Ag3LiIr2O6 has been proposed as a Kitaev magnet in proximity to the quantum spin liquid phase. We explore its microscopic Hamiltonian and magnetic ground state using many-body quantum chemistry methods and exact diagonalization tec ...
AMER PHYSICAL SOC2022Nonequilibrium quasistationary spin disordered state in ?-RuCl3
We photoexcite high-energy holon-doublon pairs as a way to alter the magnetic free energy landscape and resulting phase diagram of the frustrated honeycomb magnet ??-RuCl3. The pair recombination through multimagnon emission is tracked through the time evo ...
AMER PHYSICAL SOC2022A quantum magnetic analogue to the critical point of water
Henrik Moodysson Rønnow, Frédéric Mila, Bruce Normand, Ellen Fogh, Ludger Weber, Mohamed Zayed, Julio Antonio Larrea Jiménez, Kazimierz Conder
At the liquid-gas phase transition in water, the density has a discontinuity at atmospheric pressure; however, the line of these first-order transitions defined by increasing the applied pressure terminates at the critical point(1), a concept ubiquitous in ...
2021Dipolar-stabilized first and second-order antiskyrmions in ferrimagnetic multilayers
Skyrmions and antiskyrmions are topologically protected spin structures with opposite vorticities. Particularly in coexisting phases, these two types of magnetic quasi-particles may show fascinating physics and potential for spintronic devices. While skyrm ...
2021Order and dynamics in Kagome like compound Cu2OSO4 and other quantum magnets
This thesis presents results of studies of novel compounds modeling complex fundamental physics phenomena. Cu2OSO4 is a copper based magnetic Mott Insulator system, where spin half magnetic moments form a new type of lattice. These intrinsically quantum pi ...
EPFL2021The Solution of the Deep Boltzmann Machine on the Nishimori Line
Emanuele Mingione, Diego Alberici
The deep Boltzmann machine on the Nishimori line with a finite number of layers is exactly solved by a theorem that expresses its pressure through a finite dimensional variational problem of min-max type. In the absence of magnetic fields the order paramet ...
SPRINGER2021Tunable cooperativity in coupled spin-cavity systems
We experimentally study the tunability of the cooperativity in coupled spin-cavity systems by changing the magnetic state of the spin system via an external control parameter. As a model system, we use the skyrmion host material Cu2OSeO3 coupled to a micro ...
