Quantum Hall effect and Landau levels without spatial long-range correlations
Isac Sahlberg, Moein N. Ivaki, Kim Pöyhönen +1
The spectrum of charged particles in translation-invariant systems in a magnetic field is characterized by the Landau levels, which play a fundamental role in the thermodynamic and…
Quantum walks on random lattices: Diffusion, localization and the absence of parametric quantum speed-up
Rostislav Duda, Moein N. Ivaki, Isac Sahlberg +2
Discrete-time quantum walks, quantum generalizations of classical random walks, provide a framework for quantum information processing, quantum algorithms and quantum simulation of…
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…
Criticality in amorphous topological matter -- beyond the universal scaling paradigm
Moein N. Ivaki, Isac Sahlberg, Teemu Ojanen
We establish the theory of critical transport in amorphous Chern insulators and show that it lies beyond the current paradigm of topological criticality epitomized by the quantum H…
Topological phase transitions in glassy quantum matter
Isac Sahlberg, Alex Westström, Kim Pöyhönen +1
Amorphous systems have rapidly gained promise as novel platforms for topological matter. In this work we establish a scaling theory of amorphous topological phase transitions drive…
Amorphous topological superconductivity in a Shiba glass
Kim Pöyhönen, Isac Sahlberg, Alex Westström +1
Topological states of matter support quantized nondissipative responses and exotic quantum particles that cannot be accessed in common materials. The exceptional properties and app…
Engineering 1D topological phases on -wave superconductors
Isac Sahlberg, Alex Westström, Kim Pöyhönen +1
In this work, we study how, with the aid of impurity engineering, two-dimensional -wave superconductors can be employed as a platform for one-dimensional topological phases. We…
