Topological materials discovery has evolved at a rapid pace over the past 15 years following
the identification of the first nonmagnetic topological insulators (TIs), topological crystalline …

Transition metal dichalcogenides are layered materials which are composed of transition
metals and chalcogens of the group VIA in a 1: 2 ratio. These layered materials have been …

Two-dimensional triangular-lattice antiferromagnets are predicted under some conditions to
exhibit a quantum spin liquid ground state with no energy barrier to create emergent …

This review addresses the method of explicit calculations of interatomic exchange
interactions of magnetic materials. This involves exchange mechanisms normally referred to …

Abstract 1 T-TaS2 undergoes successive phase transitions upon cooling and eventually
enters an insulating state of mysterious origin. Some consider this state to be a band …

Strong electron correlation can induce Mott insulating behaviour and produce intriguing
states of matter such as unconventional superconductivity and quantum spin liquids. Recent …

Using density functional theory calculations, we investigate the origin of the insulating phase
and metal-insulator transition (MIT) in octahedral tantalum disulfide (1 T-TaS 2), a layered …

Combination of low-dimensionality and electron correlation is vital for exotic quantum
phenomena such as the Mott-insulating phase and high-temperature superconductivity …

Understanding microscopic processes in materials and devices that can be switched by light
requires experimental access to dynamics on nanometer length and femtosecond time …

Scaling down materials to an atomic-layer level produces rich physical and chemical
properties as exemplified in various two-dimensional (2D) crystals including graphene …
