12 August 2019 -  Hasdeo's paper on "Cyclotron motion without magnetic field" (open access) is published in the New Journal of Physics. This work describes how the familiar circulating motion of that electrons experience in a magnetic field (called cyclotron motion) can be achieved in special materials even without magnetic field. Congratulations Hasdeo!

9 July 2019 -  Our group's new proposal on "Self-induced Berry flux and out-of-equilibrium plasmonic magnetism" is published in Nature Physics. This work shows that collective modes can take on a life of their own and exhibit symmetry breaking distinct from the ground state they emerged from. See also Nature Physics news and views feature "A sudden twist".  

21 Jan 2019 -  Our group's experiment-theory collaboration with the Chia group@NTU on giant spin injection from a Ferromagnet (Co) into a semiconductor (MoS2) is published in Nature Physics. See also feature in Asian Scientist "Injecting fresh hope into spintronics".  

2 Jan 2019 -  Likun's paper on controlling quantum geometry in monolayer WTe2 is published in Physical Review B. 

5 Nov 2018 -  Our group's article on "Electron quantum metamaterials in van der Waals heterostructures" that distills out modern strategies and articulates a detailed toolbox for rationally controlling and engineering quantum materials is published in Nature Nanotechnology.

15 Aug 2018 - We welcome new group members, Jing Ma, Xiong Ying, and Arpit Arora.

9 July 2018 -  Justin is interviewed by Asian Scientist Magazine, see interview here

23 May 2018 -  Justin gives a commentary on recent developments in 2D plasmonics "Plasmon propagation pushed to the limit" published in Nature. 

17 April 2018 -  Likun's article "Plasmon geometric phase and plasmon Hall shift" is published in Physical Review X. It is also featured in Physics News and Commentary. Congratulations Likun!

Who we are and what we do:
We are a theoretical group that focuses on unveiling the inner workings and physics of quantum materials. These include 
gical materials such as Dirac/Weyl semimetals, topological insulators, and 2D van der Waals materials, amongst many others. While focussing on theory, our group has
 an unusually close rapport with experimental groups. The unique interactions arising from these often lead to new scientific discovery.
