Interaction-induced topological states of photon pairs
Andrei A. Stepanenko, Maxim A. Gorlach
To date, the concept of topological order relies heavily on the properties of single-particle bands. Only recently it has been realized that interactions can have a dramatic impact…
Topological edge states of interacting photon pairs emulated in a topolectrical circuit
Nikita A. Olekhno, Egor I. Kretov, Andrei A. Stepanenko +7
Topological physics opens up a plethora of exciting phenomena allowing to engineer disorder-robust unidirectional flows of light. Recent advances in topological protection of elect…
Kohn anomalies in momentum dependence of magnetic susceptibility of some three-dimensional systems
A. A. Stepanenko, D. O. Volkova, P. A. Igoshev +1
We study a question of presence of Kohn points, yielding at low temperatures non-analytic momentum dependence of magnetic susceptibility near its maximum, in electronic spectum of…
