A continuous confinement-deconfinement transition in a triangular quantum magnet
Suguru Hosoi, Sejun Park, Michihiro Hirata +13
A continuous transition between phases hosting distinct excitations---bosonic magnons versus fermionic spinons---is a long-sought phenomenon in quantum magnetism, analogous to the…
High-field fate of the Kitaev quantum spin liquid in -RuCl
K. Imamura, R. Ohno, Y. C. Tsuzuki +15
Kitaev quantum spin liquids (KQSLs) host fractionalized excitations described by itinerant Majorana quasiparticles and gapped fluxes (visons), providing a platform for emerge…
Revealing nonvolatile behaviors in magneto-thermal switching using microstructure-controlled superconducting composites
Keigo Ito, Yui Sakamoto, Hossein Sepehri-Amin +12
Thermal conductivity in a conductor changes by the application of an external magnetic field, which functions as a magneto-thermal switch. For superconductors, a large magneto-ther…
Microscopic evidence for imaginary charge density wave in a kagome metal
S. Suetsugu, F. Hori, M. Shibata +9
Dissipationless charge transport without any energy loss is one of the most fascinating phenomena in condensed matter physics. This extraordinary state manifests in two well-establ…
Energy-Resolved Real-Space Imaging of Orbital Nematicity in an Fe-Based Superconductor
Asato Onishi, Zifan Xu, Cédric Bareille +7
Electronic nematicity in Fe-based superconductors is manifested by spontaneous rotational symmetry breaking and the formation of nematic domains with mutually orthogonal directions…
Impact of charge-density-wave pattern on the superconducting gap in V-based kagome superconductors
T. Nagashima, K. Ishihara, Y. Yamakawa +12
Kagome metals VSb ( K, Rb, Cs) provide a compelling platform to explore the interplay between superconductivity (SC) and charge-density-wave (CDW) orders. While dist…
Topology meets time-reversal symmetry breaking in FeSeTe superconductor
M. Roppongi, Y. Cai, K. Ogawa +21
Time-reversal symmetry breaking (TRSB) in magnetic topological insulators induces a Dirac gap in the topological surface state (TSS), leading to exotic phenomena such as the quantu…
Lifting of gap nodes by disorder in ultranodal superconductor candidate FeSe1-xSx
T. Nagashima, K. Ishihara, K. Imamura +8
The observation of time-reversal symmetry breaking and large residual density of states in tetragonal FeSeS suggests a novel type of ultranodal superconducting state wi…
Ultrafast nematic-orbital excitation in FeSe
T. Shimojima, Y. Suzuki, A. Nakamura +7
The electronic nematic phase is an unconventional state of matter that spontaneously breaks the rotational symmetry of electrons. In iron-pnictides/chalcogenides and cuprates, the…
Full-gap superconductivity robust against disorder in heavy-fermion CeCu2Si2
T. Takenaka, Y. Mizukami, J. A. Wilcox +9
A key aspect of unconventional pairing by the antiferromagnetic spin-fluctuation mechanism is that the superconducting energy gap must have opposite sign on different parts of the…
High-Tc superconductivity in FeSe at high pressure: Dominant hole carriers and enhanced spin fluctuations
J. P. Sun, G. Z. Ye, P. Shahi +10
The importance of electron-hole interband interactions is widely acknowledged for iron-pnictide superconductors with high transition temperatures (Tc). However, high-Tc superconduc…
Giant superconducting fluctuations in the compensated semimetal FeSe at the BCS-BEC crossover
S. Kasahara, T. Yamashita, A. Shi +12
The physics of the crossover between weak-coupling Bardeen-Cooper-Schrieffer (BCS) and strong-coupling Bose-Einstein-condensate (BEC) limits gives a unified framework of quantum bo…
Dome-shaped magnetic order competing with high-temperature superconductivity at high pressures in FeSe
J. P. Sun, K. Matsuura, G. Z. Ye +12
The coexistence and competition between superconductivity and electronic orders, such as spin or charge density waves, have been a central issue in high transition-temperature (${T…
