Enhanced quantum sensitivity and coherence of symmetric magnetic clusters Open
Searching for highly coherent degrees of freedom in noisy solid-state environments is a major challenge in condensed matter. In disordered dipolar systems, such as magnetically doped insulators, compact clusters of two-level systems (TLS) …

Emergence of highly coherent quantum subsystems of a noisy and dense spin system Open
Quantum sensors and qubits are usually two-level systems (TLS), the quantum analogs of classical bits which assume binary values '0' or '1'. They are useful to the extent to which they can persist in quantum superpositions of '0' and '1' i…

Universal Quantum Computing Using Electronuclear Wavefunctions of Rare-Earth Ions Open
We propose a scheme for universal quantum computing based on Kramers rare-earth ions. Their nuclear spins in the presence of a Zeeman-split electronic crystal field ground state act as "passive" qubits that store quantum information. The "…

Precise determination of low energy electronuclear Hamiltonian for LiY$_{1-x}$Ho$_{x}$F$_{4}$ Open
We use complementary optical spectroscopy methods to directly measure the lowest crystal-field energies of the rare-earth quantum magnet LiY$_{1-x}$Ho$_{x}$F$_{4}$, including their hyperfine splittings, with more than 10 times higher resol…

Algorithms and image formation in orbital tomography Open
Orbital tomography has recently been established as a technique to\nreconstruct molecular orbitals directly from photoemission data using iterative\nphase retrieval algorithms. In this work, we present a detailed description of\nsteps for …

Degeneracy Lifting of Adsorbate Orbitals Imaged by High-Resolution Momentum Microscopy Open
On the topical example of the symmetry splitting of degenerate orbitals due to adsorption we drive the technique of orbital imaging by momentum microscopy (k-PEEM) ahead, demonstrating the potential of the method when performed with high a…

Optomechanical self-oscillations in an anharmonic potential: engineering a nonclassical steady state Open
We study self-oscillations of an optomechanical system, where coherent\nmechanical oscillations are induced by a driven optical or microwave cavity,\nfor the case of an anharmonic mechanical oscillator potential. A semiclassical\nanalytica…
