![]() ![]() "Whenever there is an indication of time reversal symmetry breaking in a non-magnetic materialthere must be some exotic new mechanism behind it," says Thomale. In the compound KV3Sb5, they observed the simultaneous appearance of several intricate quantum phenomena, culminating in a superconducting phase with broken time reversal symmetry. Among other ambitions, one hope is to realize a new type of superconductor," explains Thomale who holds the chair for theoretical condensed matter physics at Julius-Maximilians-Universität Würzburg, JMU.Ī research team led by the Paul Scherrer Institute (Schweiz) has now achieved a new discoveryin kagome metals. In all dedicated research groups worldwide, the search has begun to look out for kagome metals with exotic properties. "From the moment of their experimental discovery, kagome metals have unleashed a tremendous amount of research activity. That kagome metals could likewise bring about fascinating quantum effects had already been predicted in 2012 by Ronny Thomale, scientific member of the Würzburg-Dresden Cluster of Excellence ct.qmat - Complexity and Topology in Quantum Matter. Until 2018, when FeSn as the first kagome metal was found, correlated electronic states in kagome materials had typically been conceived as being generically insulating, and triggered a predominant research focus on magnetic frustrations. In condensed matter physics, materials crystallizing in a kagome lattice have first gained significant attention in the early 90's. ![]() It is a common Japanese basket pattern which is where its name derives from. As a result, the kagome lattice is a regular pattern composed of stars of David. A kagome pattern is composed of three shifted regular triangular lattices. ![]()
