Broken-Symmetry Ground States of the Heisenberg Model on the Pyrochlore Lattice

Giuseppe Carleo, Ao Chen

The spin-1/2 Heisenberg model on the pyrochlore lattice is an iconic frustrated three-dimensional spin system with a rich phase diagram. Besides hosting several ordered phases, the model is debated to possess a spin-liquid ground state when only nearest-ne ...

Microfluidics of binary liquid mixtures with temperature-dependent miscibility

Esther Amstad, Stefan Guldin

Liquid-liquid microfluidic systems rely on the intricate control over the fluid properties of either miscible or immiscible mixtures. Herein, we report on the use of partially miscible binary liquid mixtures that lend their microfluidic properties from a h ...

Why choosing the right partner is important: stabilization of ternary Cs(y)GUA(x)FA((1-y-x))PbI(3)perovskites

Michael Graetzel, Ursula Röthlisberger, Marko Mladenovic, Ariadni Boziki

Lead halide perovskites with mixtures of monovalent cations have attracted wide attention due to the possibility of preferentially stabilizing the perovskite phase with respect to photovoltaically less suitable competing phases. Here, we present a theoreti ...
