Research Theme 01

Anisotropic Fluids, Gauge Theory, and Orientation

We investigate orientational order, anisotropic interactions, and gauge-theoretic descriptions of soft matter structure, linking theory, simulation, and mesoscale organization.

Research Theme 02

Colloidal Self-Assembly and Soft Matter

We study colloidal dumbbells, droplet-mediated assembly, patchy particles, and emergent crystalline order to understand how anisotropy drives self-organization in confined and evaporative settings.

Plasmonics, Metamaterials, and Functional Absorbers

Our work combines simulation, nanostructure design, and optical characterization to create plasmonic assemblies, SERS substrates, coding absorbers, and tunable metamaterial architectures.

Research Theme 04

Functional Oxides, Photocatalysis, and Solid-State Materials

We investigate oxide nanomaterials, defect engineering, photocatalytic performance, and structure–property relationships using both experimental synthesis and computational materials approaches.

Welcome to the research website of Hai Pham-Van

Research in the group centers on condensed matter physics, soft matter, nanomaterials, and computational materials science. Led by Hai Pham-Van, Associate Professor of Physics and Head of the Department of Solid State Physics and Electronics at Hanoi National University of Education, the group combines theoretical insight, computer simulation, and experimental materials studies. Current directions include gauge-theoretic descriptions of orientational order and anisotropic fluids in statistical physics, colloidal self-assembly and patchy-particle assembly, plasmonic and SERS-active nanostructures, metamaterial absorbers, and photocatalytic functional materials.
