TCIs are topological phases of matter that are protected by crystal symmetries, including the reflection, rotation, etc. We are delighted to introduce you a really nice review of this topic. Please find the article here.
In high-energy physics, Poincaré symmetry puts strong constraints on the standard model, leading to only three different types of fermions, i.e., Dirac, Weyl, and Majorana fermions. Although several kinds of particles (such as protons) are confirmed to be Dirac fermions, the signature of Weyl and Majorana fermions is still lacking in particle physics experiments. In […]

Two-dimensional (2D) materials exhibit enhanced physical, chemical, electronic, and optical properties when compared to those of bulk materials. Graphene demands significant attention due to its superior physical and electronic characteristics among different types of 2D materials. The bilayer graphene is fabricated by the stacking of the two monolayers of graphene. The twisted bilayer graphene (tBLG) […]
Nature Physics has an article writing about the emergence of Topology in Condensed Matter Physics. The understanding of the topological effects in the world of materials would push upwards advances in the realization of Quantum Computers. Please find the article via this link.
For your information, a short review of a special kind of 2D van der Waals heterostructures – Twisted Bilayer Graphene – is made by McDonald, find it at https://physics.aps.org/articles/v12/12
Semiconducting 2D materials such as transition metal dichalcogenides are beginning to generate a lot of interest as a candidate for ultra thin body electronics and optoelectronics. There have been significant advances in the last 2 to 3 years and a shift from papers reporting fundamental properties of these materials towards proof of concept devices and […]
