Sergey Pershoguba

Sergey Pershoguba is a Visiting Assistant Professor in the Department of Physics & Astronomy at the University of New Hampshire. His research focuses on topological materials, skyrmion dynamics, superconductivity, and quantum phenomena in condensed matter systems. He teaches courses such as Mathematical Physics, Condensed Matter Physics, and Quantum Mechanics I. His work explores the interplay between topology, magnetism, and electronic behavior in materials like graphene and magnetic multilayers. Notably, he investigates optical control of topological memory, inertial effects in confined skyrmions, and nonlinear dynamics in helical lane systems. Pershoguba’s recent studies highlight experimental and theoretical advancements in understanding Dirac magnons, topological Hall effects, and energy spectra in impure graphene.

His research interests are driven by the exploration of novel quantum states and their applications in spintronics, topological computing, and nanoelectronics. He has contributed to foundational studies on current-induced dynamics in magnetic systems, quantum-well bound states at graphene interfaces, and the role of tilted magnetic fields in Dirac double layers. His work bridges theoretical models with experimental validations, advancing understanding of topological phases and their manipulation through external stimuli like light or electric fields.

Pershoguba’s articles emphasize the development of optical control mechanisms for topological memory, the study of skyrmion motion in one-dimensional geometries, and the analysis of topological effects in trivial magnetic systems. His findings contribute to both fundamental physics and potential applications in next-generation electronic and quantum technologies. While no formal awards or grants are listed, his publications reflect sustained engagement with cutting-edge topics in condensed matter physics.
