Gate-tunable quantum pathways of high harmonic generation in graphene
Nature Communications, 2022 Under strong laser fields, materials exhibit extreme non-linear optical response, such as high harmonic generation. These higher harmonics provide insights into electron behaviour in materials in sub-laser cycle timescale.

Polaritons in Van der Waals Heterostructures
Advanced Materials, 2023 Abstract2D monolayers supporting a wide variety of highly confined plasmons, phonon polaritons, and exciton polaritons can be vertically stacked in van der Waals heterostructures (vdWHs) with controlled constituent layers, stacking sequence, and even twist angles.

Van der Waals Spin Valves [PDF]
Physical Review Letters, 2018 We propose spin valves where a 2D non-magnetic conductor is intercalated between two ferromagnetic insulating layers. In this setup, the relative orientation of the magnetizations of the insulating layers can have a strong impact on the in-plane conductivity of the 2D conductor.

Two-Dimensional Six-Body van der Waals Interactions
Atoms, 2022 Van der Waals interactions, primarily attractive van der Waals interactions, have been studied over one and half centuries. However, repulsive van der Waals interactions are less widely studied than attractive van der Waals interactions. In this article,

Ultrathin van der Waals Metalenses [PDF]
Nano Letters, 2018 Ultrathin and flat optical lenses are essential for modern optical imaging, spectroscopy, and energy harvesting. Dielectric metasurfaces comprising nanoscale quasi-periodic resonator arrays are promising for such applications, as they can tailor the phase, amplitude, and polarization of light at subwavelength resolution, enabling multi-functional ...

Analytical and numerical computations of the van der Waals force in complex geometries: Application to the filtration of colloidal particles. [PDF]
, 2012 Particle capture during the filtration of colloidal dispersions depends on a complex balance between repulsive forces, such as hydrodynamic or electrostatic effects, and attractive forces, amongst them the van der Waals interaction forces.
