In "Magnetism, Frustration and Disorder" group, our research interests are centered around the physics of ‘Complex Matters’. Currently, our research activities focus on the glass transitions and associated out-of-equilibrium dynamics in frustrated magnetic systems and structural glasses. In both cases, the individual elements (magnetic moments, molecular configurations)  cannot simultaneously minimize their respective energies globally, therefore the system as a whole will continues to "age" indefinitely searching for its true ground state.

Frustrated magnetic systems can either be disordered as in spin- and superspin- glasses (magnetic nano-object assemblies) or ordered as in the Kagome lattices. In addition, we study low temperature magnetic properties in a variety of materials such as superconductors and carbon nanotubes.

Within the "magnetism" branch of our group, we are currently investigating the following topics:

• The FDT (Fluctutation and Dissipation Theorem) Violation in the Superspin Glass state of Frozen Ferrofluids

• The Dynamical Correlation Length Growth in Superspin Glass State and Anisotropy Effects
• Emergence of Collective Magnetic State in Supercrystals of Co Nanoparticles
• Direct observation of magnetization reversal in magnetic nano-pillars (soon)
