Photoinduced long-lived state in FeSe0.4Te0.6

Alberto Crepaldi

Fe(Sex)Te(1-)x compounds display a rich phase diagram, ranging from the nematicity of FeSe to the (pi, pi) magnetism of FeTe. We focus on FeSe0.4Te0.6, and exploit tr-ARPES to study its ultrafast electron dynamics following photoexcitation by near-infrared ...

Control of a polar order via magnetic field in a vector-chiral magnet

Helmuth Berger

Vector-chiral (VC) antiferromagnetism is a spiral-like ordering of spins which may allow ferroelectricity to occur due to loss of space inversion symmetry. In this Letter we report direct experimental observation of ferroelectricity in the VC phase of beta ...

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

Giuseppe Carleo

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 ...

Multiple-q noncollinear magnetism in an itinerant hexagonal magnet

Henrik Moodysson Rønnow, Jonathan White

Multiple-q spin order, i.e., a spin texture characterized by a multiple number of coexisting magnetic modulation vectors q, has recently attracted attention as a source of nontrivial magnetic topology and associated emergent phenomena. One typical example ...

Chains of mean-field models

Rüdiger Urbanke, Nicolas Macris, Seyed Hamed Hassani

We consider a collection of Curie-Weiss (CW) spin systems, possibly with a random field, each of which is placed along the positions of a one-dimensional chain. The CW systems are coupled together by a Kac-type interaction in the longitudinal direction of ...

Decomposition of copper concentrates at high-temperatures: An efficient method to remove volatile impurities

Christian Ludwig

The thermal decomposition of three synthetic copper sulfides (chalcocite (Cu2S), chalcopyrite (CuFeS2), and enargite (Cu3AsS4)) and two commercial copper concentrates has been studied on a thermobalance (T = 1173-1773 K) and an imaging furnace (T approxima ...

Quantum and Thermal Transitions Out of the Supersolid Phase of a 2D Quantum Antiferromagnet

Frédéric Mila

We investigate the thermodynamic properties of a field-induced supersolid phase in a 2D quantum antiferromagnet model. Using quantum Monte Carlo simulations, a very rich phase diagram is mapped out in the temperature—magnetic-field plane, with an extended ...
