Bose-Einstein condensation of a two-magnon bound state in a spin-one triangular lattice
Jieming Sheng, Jia-Wei Mei, Le Wang +31
In ordered magnets, the elementary excitations are spin waves (magnons), which obey Bose-Einstein statistics. Similarly to Cooper pairs in superconductors, magnons can be paired in…
Emerging quantum critical phase in a cluster spin-glass
Fang Zhang, Tao Feng, Yurong Ruan +11
Magnetic frustration has been recognized as pivotal to investigating new phases of matter in correlation-driven Kondo breakdown quantum phase transitions that are not clearly assoc…
Unraveling structural, electronic, and magnetic ambiguities in Pb1-δCrO3 with an insulating charge-transfer band structure
Jian Chen, Guozhu Song, Han Ge +4
As a recently-identified Mott system, PbCrO3 remains largely unexplored, especially for its band structure, leading to many contentious issues on its structural, electronic, and ma…
Evidence for field induced quantum spin liquid behavior in a spin-1/2 honeycomb magnet
Gaoting Lin, Mingfang Shu, Qirong Zhao +16
One of the most important issues in modern condensed matter physics is the realization of fractionalized excitations, such as the Majorana excitations in the Kitaev quantum spin li…
Local excitation of kagome spin ice magnetism in HoAgGe seen by scanning tunneling microscopy
Hanbin Deng, Tianyu Yang, Guowei Liu +20
The kagome spin ice can host frustrated magnetic excitations by flipping its local spin. Under an inelastic tunneling condition, the tip in a scanning tunneling microscope can flip…
Continuum of spin excitations in an ordered magnet
Jieming Sheng, Le Wang, Wenrui Jiang +9
Continuum of spin excitations observed in inelastic neutron scattering experiments are often considered as a strong evidence of quantum spin liquid formation. When quantum spin liq…
