Tomographic flow regime vs even-odd effect for the magnetotransport in the Corbino geometry
Grigory A. Starkov
In two dimensions, the geometric constraints due to Pauli blocking and conservation laws lead to the even-odd effect exhibited by the electron-electron scattering lengths: electron…
Converting non-Hermitian degeneracies of any order: Hierarchies of exceptional points and degeneracy manifolds
Grigory A. Starkov, Sharareh Sayyad
The emergence of various types of degeneracies plays a crucial role in optimizing and engineering different physical phenomena in non-Hermitian physics. In our work, we focus on th…
Multi-block exceptional points in open quantum systems
Aysel Shiralieva, Grigory A. Starkov, Björn Trauzettel
Open quantum systems can be approximately described by non-Hermitian Hamiltonians (NHHs) and Liouvillian superoperators. The two approaches differ by quantum jump terms correspondi…
Anomalous Knudsen effect signaling long-lived modes in 2D electron gases
Grigory A. Starkov, Björn Trauzettel
Proper analysis of electron collisions in two spatial dimensions leads to the conclusion, that the odd harmonics of the electron distribution function decay much slower than the ev…
Slowly decaying real-time oscillations in instanton crystal
Grigory A. Starkov, Konstantin B. Efetov
Instanton crystal is a fascinating phase which is encountered when the minimum of the free energy corresponds to a configuration with an imaginary-time-dependent order parameter in…
Phase transition into Instanton Crystal
Grigory A. Starkov, Konstantin B. Efetov
We propose a class of models exhibiting instanton crystal phase. In this phase, the minimum of the free energy corresponds to a configuration with an imaginary-time-dependent order…
