Pseudogap and strange metal states in the square-lattice Hubbard model: A comprehensive study
Arata Tanaka
To clarify the origin of the pseudogap and strange metal states as well as their mutual relationship in cuprate superconductors, a comprehensive study on the spectral function, Fer…
Diagnosing energy gap in quantum spin liquids via polarization amplitude
Takayuki Yokoyama, Yasuhiro Tada
Identifying whether a many-body ground state is gapped or gapless is a fundamental yet challenging problem, especially in quantum spin liquids. In this work, we develop a gap-diagn…
Ferromagnetic Order of Reduced Magnetic Moments in a Frustrated Sawtooth Chain of the Magnetic Semiconductor ZnYbS
Shinji Okada, Hiroto Suzuki, Nonoka Higa +3
In a sawtooth spin chain, competing nearest- and next-nearest-neighbor interactions suppress long-range order, yielding novel quantum states such as a spin-dimer singlet, 1/2 magne…
Polarization-based indices in quantum many-body systems: validity and extension beyond one dimension
Yasuhiro Tada
The expectation value of the twist operator has been widely used as a polarization-based index for gapped and gapless phases in interacting quantum many-body systems. Although nume…
Highly fluctuating double- magnetic order in the van der Waals metal CeTe
Ryutaro Okuma, Yuita Fujisawa, Natsumi Maekawa +5
CeTe is a van der Waals antiferromagnet composed of magnetic [CeTe] layers coupled to highly conducting Te square nets. Its simple quasi-two-dimensional electronic…
Piezomagnetic effect of a rare-earth-based altermagnet TbPt6Al3
Ryohei Oishi, Kazunori Umeo, Takuya Aoyama +2
We have investigated the piezomagnetic (PZM) effect of the rare-earth-based g-wave altermagnet TbPt6Al3 by magnetization measurements of single-crystalline samples under uniaxial s…
