Interplay of Valley, Orbital, Spin, and Layer Degrees of Freedom in Ta $_{2}$ CS $_{2}$ MXene

Kunal Dutta, Anupam Mondal, Sayantika Bhowal +2

We show that the MXene Ta $_{2}$ CS $_{2}$ provides an excellent platform for hosting multiple coupled degrees of freedom, viz., valley, spin, orbital, and layer. The interplay among thes…

Novel Quantum Spin Liquid States in the $S = \frac{1}{2}$ Three-Dimensional Compound Y $_{3}$ Cu $_{2}$ Sb $_{3}$ O $_{14}$

Saikat Nandi, Rounak Das, M. Hemmida +10

The three-dimensional $S = \frac{1}{2}$ system Y $_{3}$ Cu $_{2}$ Sb $_{3}$ O $_{14}$ consists of two inequivalent Cu $^{2 +}$ sites, each forming an edge shared triangular lattice. Our m…

Gapless Edge-Modes and Topology in the Qi-Wu-Zhang Model: A Real-Space Analysis

Arjo Dasgupta, Indra Dasgupta

The topological phase transition in the Qi-Wu-Zhang model is studied using a real-space approach. An effective Hamiltonian for the topologically protected edge-modes in a finite-si…

The Anatomy of a Topological Phase Transition in a 2D Chern Insulator

Arjo Dasgupta, Indra Dasgupta

The onset of the topological phase transition in a two-dimensional model for a Chern Insulator, namely the Qi-Wu-Zhang(QWZ) model, is illustrated, with particular emphasis on the a…
