PEG-Grafted Silver Nanoparticles:Implications for Plasmonics and Photonics

ML-guided discovery of ternary compounds involving immiscible elements

Adaptive quantum circuit construction for ground state preparation of multiorbital impurity models

Different variational quantum eigensolvers for ground state preparation of multiorbital embedding impurity models were benchmarked in the presence of hardware noise.

Tuning electronic coupling in bilayer graphenevis-á-vis metal intercalation

Gd intercalation introduces an exceptionally large transverse displacement field acting on the overlying Bernal - stacked bilayer graphene (BLG).

Imaging exciton-plasmon polaritons in WSe2/Au heterostructures

Exciton-plasmon polaritons in WSe2/Au heterostructures are imaged, which show a strong coupling between excitons in WSe2 and surface plasmons on gold.

Accelerating the discovery of novel materials using a machine learning guided framework

Novel low-energy La-Si-P ternary compounds are efficiently predicted by an ML-guided framework which dramatically (~100 times) accelerates the pace of materials discovery.

Terahertz nano-imaging of a perovskite solar cell

Photo-carrier transport is mapped and visualized at the sub-grain level on a perovskite solar cell material with nanometer spatial resolution and terahertz frequency scales.

New family of materials hosting magnetic Fermi arcs

Fermi arcs were so far found only in superconducting cuprates and certain class of semimetals, where they span pairs of Weyl fermions of opposite chirality. We recently discovered Fermi arcs that emerge in a simple cubic compound, NdBi, when the sample orders antiferromagnetically.

Weak itinerant magnetic phases of La2Ni7

This is the first successful measurement of the magnetic structures of this well studied compound whose chemical structure was solved circa 1969.
