Broken Kramers' degeneracy in altermagnetic MnTe
Suyoung Lee, Sangjae Lee, Saegyeol Jung +9
Altermagnetism is a newly identified fundamental class of magnetism with vanishing net magnetization and time-reversal symmetry broken electronic structure. Probing the unusual ele…
Mn(PtPd)P: Isovalent Tuning of Mn Sublattice Magnetic Order
Tyler J. Slade, Ranuri S. Dissanayaka Mudiyanselage, Nao Furukawa +12
We report the growth and characterization of MnPdP, a ferromagnet with T 295 K, and conduct a substitutional study with its antiferromagnetic analogue MnPtP.…
Dynamical mean-field theory study of a ferromagnetic CrI3 monolayer
Chang-Jong Kang, Jeonghoon Hong, Jeongwoo Kim
We have employed one of the well-known many-body techniques, density functional theory plus dynamical mean-field theory (DFT + DMFT), to investigate the electronic structure of fer…
Theory-guided investigation on magnetic evolution of MnPtPdP and discovery of anti-CeCoIn-type ferromagnetic MnPdP
Ranuri S. Dissanayaka Mudiyanselage, Chang-Jong Kang, Kaya Wei +5
We report the magnetic changes from canted antiferromagnetic to ferromagnetic orderings in anti-115-type MnPtPdP ( = 1, 2, 2.5, 3, 4, and 5) and the discovery of a n…
Vacancy defect control of colossal thermopower in FeSb2
Qianheng Du, Lijun Wu, Huibo Cao +9
Iron diantimonide is a material with the highest known thermoelectric power. By combining scanning transmission electron microscope study with electronic transport neutron, X-ray s…
Ultrafast triggering of insulator-metal transition in two-dimensional VSe
Deepnarayan Biswas, Alfred J. H. Jones, Paulina Majchrzak +24
Assembling transition metal dichalcogenides (TMDCs) at the two-dimensional (2D) limit is a promising approach for tailoring emerging states of matter such as superconductivity or c…
Strong interband interaction in the excitonic insulator phase of TaNiSe
Jinwon Lee, Chang-Jong Kang, Man Jin Eom +3
Excitonic insulator (EI) was proposed in 60's as a distinct insulating state originating from pure electronic interaction, but its material realization has been elusive with extrem…
Material design of indium based compounds: possible candidates for charge, valence, and bond disproportionation and superconductivity
Chang-Jong Kang, Gabriel Kotliar
We design and investigate the physical properties of new indium compounds AInX (A = alkali metals, X = F or Cl). We find nine new In based materials in their ground state and…
Study for material analogs of FeSb: material design for thermoelectric materials
Chang-Jong Kang, Gabriel Kotliar
Using the \emph{ab initio} evolutionary algorithm (implemented in USPEX) and electronic structure calculations we investigate the properties of a new thermoelectric material FeSbAs…
Temperature-dependent evolutions of excitonic superfluid plasma frequency in a srong excitonic insulator candidate, TaNiSe
Yu-Seong Seo, Man Jin Eom, Jun Sung Kim +3
We investigate an interesting anisotropic van der Waals material, TaNiSe, using optical spectroscopy. TaNiSe has been known as one of the few excitonic insu…
Pressure-induced Phonon Softenings and the Structural and Magnetic Transitions in CrO
Sooran Kim, Kyoo Kim, Chang-Jong Kang +1
To investigate the pressure-induced structural transitions of chromium dioxide (CrO), phonon dispersions and total energy band structures are calculated as a function of pres…
