A diamond spin qubit scanning probe microscope
The properties of a physical system only exist in relation to its environment. This thesis presents the development of a novel spin qubit scanning probe microscope operating over a wide range of environmental conditions. The qubit, which sits at the heart ...
EPFL2023Large Orbital Moment of Two Coupled Spin-Half Co Ions in a Complex on Gold
Stefano Rusponi, Chao Li, Boris Sorokin
The magnetic propertiesof transition-metal ions aregenerallydescribed by the atomic spins of the ions and their exchange coupling.The orbital moment, usually largely quenched due the ligand field,is then seen as a perturbation. In such a scheme, S = 1/2 io ...
AMER CHEMICAL SOC2023Ultrafast control of emergent quantum matter probed by electron microscopy
Benoît Guilhem Michel Binh Truc
In the quest for controlling materials' properties, light as an external stimulus has a special place as it can create new states of matter and enable their ultrafast manipulation. In particular, spintronics, an exciting emergent field relying on the elect ...
EPFL2023Fermi energy determination for advanced smearing techniques
Nicola Marzari, Flaviano José Dos Santos
Smearing techniques are widely used in first-principles calculations of metallic and magnetic materials where they improve the accuracy of Brillouin-zone sampling and lessen the impact of level-crossing instabilities. Smearing introduces a fictitious elect ...
AMER PHYSICAL SOC2023Eight-vertex criticality in the interacting Kitaev chain
Frédéric Mila, Natalia Chepiga
We show that including pairing and repulsion into the description of one-dimensional spinless fermions, as in the domain wall theory of commensurate melting or the interacting Kitaev chain, leads, for strong enough repulsion, to a line of critical points i ...
AMER PHYSICAL SOC2023Possible 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 SOC2023Characterisation of detachment in the MAST-U Super-X divertor using multi-wavelength imaging of 2D atomic and molecular emission processes
Basil Duval, Artur Perek, Kevin Henricus Annemarie Verhaegh
In this work, we provide the first 2D spatially resolved description of radiative detachment in MAST-U Super-X L-mode divertor plasmas. The Super-X magnetic configuration was designed to achieve reduced heat- and particle loads at the divertor target compa ...
IOP Publishing Ltd2023Heteroclinic orbits for a system of amplitude equations for orthogonal domain walls
Using a variational method, we prove the existence of heteroclinic solutions for a 6-dimensional system of ordinary differential equations. We derive this system from the classical Benard-Rayleigh problem near the convective instability threshold. The cons ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2023Magnetic excitations in the topological semimetal YbMnSb2
We report neutron scattering measurements on YbMnSb2 which shed light on the nature of the magnetic moments and their interaction with Dirac fermions. Using half-polarized neutron diffraction we measured the field-induced magnetization distribution in the ...
AMER PHYSICAL SOC2023Quantum engineering and detection of advanced radiation beams
Controlling and shaping radiation beams is fundamental for a better understanding of radiation-matter interaction and advancing experimental techniques for material characterization at high spatial resolution.In particular, the current trend in the miniatu ...
