Investigating metastability in the bandstructure of correlated matter by ultrafast photoemission spectroscopy

Advancements of laser technologies and material science have revolutionized the ability to manipulate matter through irradiation with ultrafast light pulses. This progress enables not only the study of out-of-equilibrium dynamics but also allows for the se ...

Multinode quantum spin liquids in extended Kitaev honeycomb models

Bruce Normand

Variational Monte Carlo (VMC) studies of extended Kitaev honeycomb models reveal a series of multinode quantum spin liquids (QSLs). They have an emergent Z2 gauge structure, a discrete number of symmetry-protected Majorana cones, and form Abelian or non-Ab ...

Induced polarization imparts piezoelectricity in noncrystalline polymer films

Dragan Damjanovic

Piezoelectric materials produce a linear deformation in response to an applied electric field and are essential for precision-control devices. The conventional view is that polymers must be crystalline and possess remanent polarization after artificial pol ...

Analytical Model for Calculating Gain Pattern of Antennas Implanted in Large Host Bodies

Anja Skrivervik, Mingxiang Gao, Sujith Raman

This communication presents a method for the fast and accurate estimation of the gain pattern and maximum gain of an implanted antenna including the effect of the host body, under the assumption that the latter is electrically large. The estimation procedu ...

Microwave Spectroscopy of the Low-Temperature Skyrmion State in Cu2OSeO3

Helmuth Berger

In the cubic chiral magnet Cu2OSeO3 a low-temperature skyrmion state (LTS) and a concomitant tilted conical state are observed for magnetic fields parallel to h100i. Here, we report on the dynamic resonances of these novel magnetic states. After promoting ...

Energetics of turbulence generated by chiral MHD dynamos

Salim Bennouna

An asymmetry in the number density of left- and right-handed fermions is known to give rise to a new term in the induction equation that can result in a dynamo instability. At high temperatures, when a chiral asymmetry can survive for long enough, this chi ...
