We propose to exploit currently available tunnel ferromagnetic Josephson junctions to
realize a hybrid superconducting qubit. We show that the characteristic hysteretic behavior …

The manipulation of the anomalous Hall effect (AHE) by controlling magnetization is of great
interest in condensed matter physics due to its potential application for the practical design …

Direct detection of spontaneous spin fluctuations, or “magnetization noise,” is emerging as a
powerful means of revealing and studying magnetic excitations in both natural and artificial …

We present general quantum mechanical expressions for higher-order moments, cumulants,
and spectra of continuously measured quantum systems with applications in spin noise …

Artificial spin ices (ASIs) are interacting arrays of lithographically defined nanomagnets in
which novel, frustrated magnetic phases can be intentionally designed. A key emergent …

The analysis of a continuous measurement record z (t) poses a fundamental challenge in
quantum measurement theory. Different approaches were used in the past as records can …

The coexistence between ferromagnetic ordering and superconducting transport in tunnel
ferromagnetic Josephson junctions (SFS JJs) accounts for a wide range of unconventional …

Combining wide-field magneto-optical Kerr microscopy with a time-lapse analysis scheme
allows investigating magnetization fluctuations with high spatial as well as temporal …

Applied magnetic fields are an important tuning parameter for artificial spin ice (ASI)
systems, as they can drive phase transitions between different magnetic ground states or …

Fundamental properties of the spin-noise signal formation in a quantum-dot microcavity are
studied by measuring the angular characteristics of the scattered light intensity. A distributed …
