Bogdan OSTAHIE

Bogdan OSTAHIE is a Scientific Researcher III at the National Institute of Materials Physics (NIMP), Romania, affiliated with the Laboratory of Theoretical Physics and Computational Modeling. His primary research focuses on topological quantum phenomena in condensed matter systems.

Education:

• PhD in Theoretical Physics, University of Bucharest (2018)
• Master Degree in Condensed Matter Physics, University of Bucharest (2010-2012)
• Graduate studies, Faculty of Physics, University of Bucharest (2007-2010)

OSTAHIE's research centers on quantum transport in topological and low-dimensional quantum structures. His work spans Floquet topological insulators, non-Hermitian quantum systems, edge state engineering, and quantum Hall phenomena. He employs analytical and numerical methods to study spectral properties, transport characteristics, and topological phase transitions in systems ranging from 2D lattices to heterostructures. His recent work demonstrates how symmetry breaking, disorder, and external fields manipulate topological states for potential quantum device applications.

Analysis of his publications reveals three dominant research thrusts: (1) Floquet engineering of topological phases (2023-2025), particularly second-order corner states and light-induced topological transitions; (2) Non-Hermitian extensions of topological systems (2021-2022), exploring exceptional points and chiral disorder effects; (3) Foundational work on graphene and phosphorene topological systems (2014-2018), establishing edge state mechanisms for quantum Hall effects. His publications consistently bridge theoretical predictions with experimental signatures like quantum transport measurements.

Scientific Recognition:

• Radu Grigorovici Prize of the Romanian Academy (2016)

OSTAHIE leads the project 'Edge states manifestation in non-Hermitian topological systems' (PD-type, 2020-2022), demonstrating active grant funding. His collaborations span international institutions including University of Granada (Spain) and Budapest University of Technology (Hungary). While no formal students are listed, his work appears in premier journals like Physical Review B and New Journal of Physics, indicating significant contributions to theoretical condensed matter physics. His laboratory focuses on computational modeling of quantum structures using tight-binding approaches and non-Hermitian quantum transport formalisms.
