Revealing Rotational Symmetry Breaking Charge-density Wave Order in Kagome Superconductor (Rb, K)VSb by Ultrafast Pump-probe Experiments
Qinwen Deng, Hengxin Tan, Brenden R. Ortiz +3
The recently discovered Kagome superconductor AVSb (where A refers to K, Rb, Cs) has stimulated widespread research interest due to its interplay of non-trivial topology an…
Interplay of - and -states in RbTiBi and CsTiBi flat-band kagome metals
M. Wenzel, E. Uykur, A. A. Tsirlin +4
Shifting the Fermi level of the celebrated (135) compounds into proximity of flat bands strongly enhances electronic correlations and severely affects the formation of de…
Interleaved bond frustration in a triangular lattice antiferromagnet
S. J. Gomez Alvarado, J. R. Chamorro, D. Rout +14
Frustration of long-range order via lattice geometries serves to amplify fluctuations of the order parameter and generate unconventional ground states that are highly sensitive to…
Stability frontiers in the AMX kagome metals: The LnNbSn (Ln:Ce-Lu,Y) family and density-wave transition in LuNbSn
Brenden R. Ortiz, William R. Meier, Ganesh Pokharel +16
The kagome motif is a versatile platform for condensed matter physics, hosting rich interactions between magnetic, electronic, and structural degrees of freedom. In recent years, t…
Pomeranchuk instability from electronic correlations in CsTiBi kagome metal
Chiara Bigi, Matteo Dürrnagel, Lennart Klebl +19
Among many-body instabilities in correlated quantum systems, electronic nematicity, defined by the spontaneous breaking of rotational symmetry, has emerged as a critical phenomenon…
Frustrated Ising charge correlations in the kagome metal ScVSn
S. J. Gomez Alvarado, G. Pokharel, B. R. Ortiz +4
Here we resolve the real-space nature of the high-temperature, short-range charge correlations in the kagome metal ScVSn. Diffuse scattering appears along a frustrated wave…
Pressure tuning of intrinsic and extrinsic sources to the anomalous Hall effect in CrGeTe
Gili Scharf, Daniel Guterding, Bar Hen +7
The integrated Berry curvature is a geometric property that has dramatic implications for material properties. This study investigates the integrated Berry curvature and other cont…
Revisiting spin ice physics in the ferromagnetic Ising pyrochlore PrSnO
Brenden R. Ortiz, Paul M. Sarte, Ganesh Pokharel +12
Pyrochlore materials are characterized by their hallmark network of corner-sharing rare-earth tetrahedra, which can produce a wide array of complex magnetic ground states. Ferromag…
Evidence for an odd-parity nematic phase above the charge density wave transition in kagome metal CsVSb
T. Asaba, A. Onishi, Y. Kageyama +16
The quest for fascinating quantum states arising from the interplay between correlation, frustration, and topology is at the forefront of condensed-matter physics. Recently discove…
Geometry of the charge density wave in kagom metal AVSb
H. Miao, H. X. Li, W. R. Meier +10
Kagom lattice is a fertile platform for topological and intertwined electronic excitations. Recently, experimental evidence of an unconventional charge density wave (CDW) is o…
