Bond-density-wave orders induced by geometric frustration in the kagome metal CeRu3Si2
Ryo Misawa, Shunsuke Kitou, Rinsuke Yamada +9
Geometric frustration gives rise to vast manifolds of degenerate ground states and competing orders in spin and charge systems. Typically, classical ground states are governed by a…
Polar, checkerboard charge order in bilayer nickelate La3Ni2O7
Ryo Misawa, Shunsuke Kitou, Jian-Ping Sun +6
Competing charge and spin orders are central to uncovering the nature of unconventional superconductivity. Here we utilize synchrotron X-ray diffraction on a high-quality single cr…
Stripe antiferromagnetism in van der Waals metal HoTe3 decoupled from charge density wave order
Weiyi Yun, Ryota Nakano, Ryo Misawa +10
The () family of layered van der Waals (vdW) compounds hosts coexisting magnetic and charge density wave (CDW) orders, yet the interplay bet…
Bulk superconductivity in the kagome metal YRu3B2
Tobi Gaggl, Ryo Misawa, Markus Kriener +3
Materials with a kagome sublattice have been heavily studied recently for their exotic electronic band structure, structural frustration, high-temperature charge order transitions,…
Successive orthorhombic distortions in kagome metals by molecular orbital formation
Ryo Misawa, Shunsuke Kitou, Rinsuke Yamada +12
The kagome lattice, with its inherent frustration, hosts a plethora of exotic phenomena, including the emergence of charge density wave order. The high rotational sym…
Chemical enhancement of superconductivity in LaRu3Si2 with mode-selective coupling between kagome phonons and flat bands
Ryo Misawa, Markus Kriener, Rinsuke Yamada +4
In kagome metals, flat electronic bands induced by frustrated hopping are a platform for strong electron correlations. In particular, a selective coupling of flat band states to ce…
