11 Dec 2019 - Likun and Jing's paper on "Gate tunable flatbands in van der Waals patterned dielectric superlattices" in published in 2D materials (Open-access). This work a simple strategy for creating gate tunable flat bands in materials such as WS2 without the need for a magic angle. Congratulations Likun and Jing!
21 Nov 2019 - Likun's paper "Shift vector as geometric origin of beam shifts" is published in Physical Review B (Rapid Communication). This work describes how the unusual displacement of a wave beam as it reflects off a boundary can be captured by the geometry of wavefunctions in the propagating media. Congratulations Likun!
18 October 2019 - Our group's theory-experiment collaboration with the Deshmukh group @TIFR on how a topologically trivial band can pick up a non-trivial quantum oscillation phase shift is published in Science Advances. This work showed a Berry phase "proximity effect" that arises from a filling induced coupling between trivial and non-trivial bands.
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" distilling out modern strategies for controlling 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!
