Impact
The NHSUPER project contributes to the development of non-Hermitian physics by formulating a general theory of non-Hermitian superconductivity in fermionic systems. By treating superconductors as open quantum systems and using the Lindblad formalism, the project’s results clarify the role of dissipation, impurities, Coulomb interactions, and electron–phonon coupling in the dynamics of non-Hermitian superconductors.
The cognitive impact lies in generating new concepts and physical models relevant for non-Hermitian superconductors, publishing results in high-impact scientific journals, presenting them at international conferences, and developing advanced skills for young researchers and PhD students. These achievements strengthen Romania’s position in frontier fundamental research in condensed matter physics.
Although the project is focused on fundamental physics, it has medium- and long-term socio-economic potential through contributions to quantum technologies. The results may support the development of quantum architectures based on multi-level superconducting qubits, where dissipation is exploited as a resource. Simulating non-Hermitian systems in circuit quantum electrodynamics can open new directions for controlling and manipulating quantum systems, with applications in quantum computing, quantum sensors, and advanced quantum devices. The project also supports the development of advanced expertise in quantum research, reinforcing innovation capacity in high-tech domains.
