A New Moiré Platform Based on M-Point Twisting
Dumitru Călugăru, Yi Jiang, Haoyu Hu +9
We introduce a new class of moiré systems and materials based on monolayers with triangular lattices and low-energy states at the M points of the Brillouin zone. These M-point moir…
2D Theoretically Twistable Material Database
Yi Jiang, Urko Petralanda, Grigorii Skorupskii +30
The study of twisted two-dimensional (2D) materials, where twisting layers create moiré superlattices, has created opportunities for investigating topological phases and strongly c…
Spin Hall and Edelstein Effects in Novel Chiral Noncollinear Altermagnets
Mengli Hu, Oleg Janson, Claudia Felser +3
Altermagnets are a newly discovered class of magnetic phases that combine the spin polarization behavior of ferromagnetic band structures with the vanishing net magnetization chara…
Atomic-scale mapping of superconductivity in the incoherent CDW mosaic phase of a transition metal dichalcogenide
Sandra Sajan, Haojie Guo, Tarushi Agarwal +6
The emergence of superconductivity in the octahedrally coordinated (1T) phase of TaS2 is preceded by the intriguing loss of long-range order in the charge density wave (CDW). Such…
Interlayer charge transfer induced by electronic instabilities in the natural van der Waals hetrostructure 4H-TaS
R. Mathew Roy, X. Feng, M. Wenzel +6
The natural van der Waals heterostructure 4H-TaS composed of alternating 1T- and 1H-TaS layers serves as a platform for investigating the electronic correlations and la…
Catalogue of Phonon Instabilities in Symmetry Group 191 Kagome MTZ Materials
X. Feng, Y. Jiang, H. Hu +6
Kagome materials manifest rich physical properties due to the emergence of abundant electronic phases. Here, we carry out a high-throughput first-principles study of the kagome 1:6…
Recognizing molecular chirality via twisted 2D materials
Lorenzo Cavicchi, Mayra Peralta, Álvaro Moreno +6
Chirality pervades natural processes from the atomic to the cosmic scales, crucially impacting molecular chemistry and pharmaceutics. Traditional chirality sensing methods face cha…
Twisted bilayer graphene for enantiomeric sensing of chiral molecules
Álvaro Moreno, Lorenzo Cavicchi, Xia Wang +8
Selective sensing of chiral molecules is a key aspect in fields spanning biology, chemistry, and pharmacology. However, conventional optical methods, such as circular dichroism (CD…
Directionally Locked Heteroepitaxy with a Structurally Modulated van der Waals Material
Nitish Mathur, Guangming Cheng, Francesc Ballester +17
Precise orientation of symmetry-mismatched epilayers on van der Waals (vdW) substrates via heteroepitaxy has commonly been achieved through surface treatment processes to accommoda…
New magnetic topological materials from high-throughput search
Iñigo Robredo, Yuanfeng Xu, Yi Jiang +5
We conducted a high-throughput search for topological magnetic materials on 522 new, experimentally reported commensurate magnetic structures from MAGNDATA, doubling the number of…
Charge transfer in T/H heterostructures of transition metal dichalcogenides
Irián Sánchez-Ramírez, Maia G. Vergniory, Fernando de Juan
The charge density wave state of the T polytype of MX (M=Nb,Ta, X=S, Se) is known to host a half-filled flat band, which electronic correlations driv…
Magnetic Weyl-Kondo semimetals induced by quantum fluctuations
Yuan Fang, Lei Chen, Andrey Prokofiev +5
Weyl-Kondo semimetals are strongly correlated topological semimetals that develop through the cooperation of the Kondo effect with space group symmetries. The Kondo effect, capturi…
