Quartic multifractality and finite-size corrections at the spin quantum Hall transition
Martin Puschmann, Daniel Hernangómez-Pérez, Bruno Lang +2
The spin quantum Hall (or class C) transition represents one of the few localization-delocalization transitions for which some of the critical exponents are known exactly. Not know…
Green's functions on a renormalized lattice: An improved method for the integer quantum Hall transition
Martin Puschmann, Thomas Vojta
We introduce a performance-optimized method to simulate localization problems on bipartite tight-binding lattices. It combines an exact renormalization group step to reduce the spa…
Inhomogeneous mean-field approach to collective excitations in disordered interacting bosons
Martin Puschmann, João C. Getelina, José A. Hoyos +1
We develop an inhomogeneous quantum mean-field approach to the behavior of collective excitations across the superfluid-Mott glass quantum phase transition in two dimensions, compl…
