Physics – Golden Ticket to Stockholm
A bit of a no-brainer. With several experiments around the world searching for a sign of the elusive dark matter particle, it’s obvious that a successful “hit” would merit a Nobel Prize. “The dark matter problem is one of the most important in physics with many implications in its solution,” says quantum physicist Steve Girvin…

Pivotal Discovery Signals a Huge Leap Forward in Fusion Energy Reactor Progress
A team of researchers has introduced a method to mitigate damaging runaway electrons in tokamak fusion devices. The strategy harnesses Alfvén waves to disrupt the damaging cycle of runaway electrons. This discovery holds promise for the advancement of fusion energy, with potential implications for the ongoing ITER project in France. Researchers have utilized Alfvén waves…

Efficient magnetic switching in a correlated spin glass
Ferrimagnetic switching Figure 1 a shows XMCD spectra measured at 10 K in total electron yield (TEY) mode while applying magnetic fields up to ±6 T. As will be discussed later, the dichroic signal does not saturate at our maximum B-fields due to a paramagnetic spin-glass state, similar to the Cd1−xMnxTe DMS system23. The top-inset is…

NaRuO2: Kitaev-Heisenberg exchange in triangular-lattice setting
On-site multiplet structure and intersite couplings in NaRuO2 NaRuO2 is rather unique, a realization of jeff ≈ 1/2 \({t}_{2g}^{5}\) moments on a triangular network of edge-sharing RuO6 octahedra (see Fig. 2). The basic Ru3+ 4d5 multiplet structure in the specific delafossite crystalline setting of NaRuO2 is illustrated in Table 1, as obtained by quantum chemical8 complete-active-space self-consistent-field…

Defeating depolarizing fields with artificial flux closure in ultrathin ferroelectrics
Uncompensated bound charges at the surfaces of ferroelectric films trigger a depolarizing field1. It is oriented opposite to the spontaneous polarization and highest when this polarization is normal to the surface—the preferred orientation for ferroelectric devices. Thus, the ferroelectric properties are attenuated with decreasing thickness and completely disappear below about 5 unit cells (u.c.) in most…
