Confined and deconfined spinon excitations in the rectangular-lattice quantum antiferromagnet
N. E. Shaik, E. Fogh, B. Dalla Piazza +3
Fractionalization remains one of the most fascinating manifestations of strong interactions in quantum many-body systems. In quantum magnetism, the existence of spinons -- collecti…
Dielectric response of Anderson and pseudogapped insulators
M. V. Feigel'man, D. A. Ivanov, E. Cuevas
Using a combination of analytic and numerical methods, we study the polarizability of a (non-interacting) Anderson insulator in one, two, and three dimensions and demonstrate that,…
Low-energy dynamical response of an Anderson insulator with local attraction
D. A. Ivanov, M. V. Feigel'man
The low-frequency dynamical response of an Anderson insulator is dominated by so-called Mott resonances: hybridization of pairs of states close in energy, but separated spatially.…
Anderson localization of a Majorana fermion
D. A. Ivanov, P. M. Ostrovsky, M. A. Skvortsov
Isolated Majorana fermion states can be produced at the boundary of a topological superconductor in a quasi-one-dimensional geometry. If such a superconductor is connected to a dis…
Hybridization of wave functions in one-dimensional localization
D. A. Ivanov, M. A. Skvortsov, P. M. Ostrovsky +1
A quantum particle can be localized in a disordered potential, the effect known as Anderson localization. In such a system, correlations of wave functions at very close energies ma…
Vison excitations in near-critical quantum dimer models
Grégory Strübi, Dmitri A. Ivanov
We study vison excitations in a quantum dimer model interpolating between the Rokhsar-Kivelson models on the square and triangular lattices. In the square-lattice case, the model i…
