Transition metal dichalcogenides display a high technological potential due to their wide range of electronic ground states. Here, we unveil that by tuning hydrostatic pressure P, a cascade of electronic phase transitions can be induced in the few-layer transition metal dichalcogenide 1T'-WS. As P increases, we observe the suppression of superconductivity with the concomitant emergence of an anomalous Hall effect (AHE) at GPa.

Home Treatment (HT) in child and adolescent psychiatry is an increasingly important topic in the current context of global crises and strained mental health systems. We implemented a HT program provided by a multiprofessional treatment team and compared long-term outcomes of 27 patients (48% female, Ø15.15 ± 2.

Results of magnetotransport measurements are reported on KVSb thin flakes under pressure. The zero-field electrical resistance reveals an additional anomaly emerging under pressure (p), marking a previously unidentified phase boundary T*(p). Together with the established T(p) and T(p), denoting the charge-density-wave transition and a superconducting transition, respectively, the temperature-pressure phase diagram of KVSb features a rich interplay among multiple phases.

Spin moiré superlattices (SMSs) have been proposed as a magnetic analog of crystallographic moiré systems and a source of electron minibands offering vector-field moiré tunability and Berry curvature effects. However, it has proven challenging to realize an SMS in which a large exchange coupling is transmitted between conduction electrons and localized spins. Furthermore, most systems have carrier mean free paths shorter than their spin moiré lattice constant , inhibiting miniband formation.
