Research Interests:

• Nanomagnetism
• Magnetic metamaterials, especially Artificial Spin Ice Systems
• Optical and magneto-optical metamaterials (metaoptics)
• Classical frustrated spin models
• Polarimetry and optical sensing

Dr. Chioar鈥檚 research group focuses on studying magnetic and optical metamaterials, both from a fundamental science standpoint and for potential applications in computing and sensing technologies. These nanoarchitectures offer a bountiful playground to design, visualize, control, and harness collective many-body phenomena at the forefront of nanomagnetism and nanooptics. The research employs various magnetic and optical characterization techniques and can also be complemented by numerical/theoretical undertakings. Current research projects focus on artificial spin ice systems and the investigation of new magneto-optical metamaterial designs.
