Jaime Díez Mérida

Dr. Jaime Díez Mérida is a Postdoctoral Researcher at the Institute of Photonic Sciences (ICFO), focusing on quantum materials and nanodevices. His research group specializes in studying 2D Quantum Materials, particularly magic-angle twisted bilayer graphene (MATBG), exploring superconductivity, Josephson junctions, and electronic phase transitions. He holds a PhD in Photonics from the Universitat Politècnica de Catalunya (Spain).

His work emphasizes understanding emergent phenomena in twisted bilayer systems, including heavy electron behavior, quantum criticality, and topological states. Recent studies investigate ultrafast electron-phonon cooling mechanisms and symmetry-breaking effects in MATBG-based devices. His experimental methods include advanced fabrication techniques for high-homogeneity devices and gate-defined structures.

Key contributions include pioneering work on many-body ground states in MATBG and probing superconducting proximity effects via Josephson junctions. His research bridges condensed matter physics and nanotechnology, addressing fundamental questions about electronic correlations and quantum transport in 2D systems.

He collaborates on projects involving thermoelectric responses in pn-junctions and topological fractional charge phenomena in Josephson arrays. His work has implications for quantum technologies and understanding 'strange metal' behavior in correlated systems.
