Topological Random Fractals
Moein N. Ivaki, Isac Sahlberg, Kim Pöyhönen +1
We introduce the notion of topological electronic states on random lattices in non-integer dimensions. By considering a class model on critical percolation clusters embedded in…
Identifying Chern numbers of superconductors from local measurements
Paul Baireuther, Marcin Płodzień, Teemu Ojanen +2
Fascination in topological materials originates from their remarkable response properties and exotic quasiparticles which can be utilized in quantum technologies. In particular, la…
Many-body entanglement and topology from uncertainties and measurement-induced modes
Kim Pöyhönen, Ali G. Moghaddam, Teemu Ojanen
We present universal characteristics of quantum entanglement and topology through virtual entanglement modes that fluctuate into existence in subsystem measurements. For generic in…
Entanglement echo and dynamical entanglement transitions
Kim Pöyhönen, Teemu Ojanen
We formulate dynamical phase transitions in subsystems embedded in larger quantum systems. Introducing the entanglement echo as an overlap of the initial and instantaneous entangle…
