Topological polarization, dual invariants, and surface flat band in crystalline insulators
J. Nissinen, Tero T. Heikkila, G. E. Volovik
We describe a three-dimensional crystalline topological insulator (TI) phase of matter that exhibits spontaneous polarization. This polarization results from the presence of (appro…
Composite topological objects in topological superfluids
G. E. Volovik
Superfluid phases of He discovered in 1972 opened the new area of the application of topological methods to condensed matter systems. Due to the multi-component order parameter…
Polar phase of superfluid He: Dirac lines in the parameter and momentum spaces
G. E. Volovik
The time reversal symmetric polar phase of the spin-triplet superfluid He has two types of Dirac nodal lines. In addition to the Dirac loop in the spectrum of the fermionic Bog…
Topological Superfluids
G. E. Volovik
There are many topological faces of the superfluid phases of He. These superfluids contain various topological defects and textures. The momentum space topology of these superf…
Topology of the planar phase of superfluid He and bulk-boundary correspondence for three dimensional topological superconductors
Yuriy Makhlin, Mikhail Silaev, G. E. Volovik
We provide topological classification of possible phases with the symmetry of the planar phase of superfluid He. Compared to the B-phase (class DIII in classification of Altlan…
Flat band in topological matter: possible route to room-temperature superconductivity
G. E. Volovik
Topological media are systems whose properties are protected by topology and thus are robust to deformations of the system. In topological insulators and superconductors the bulk-s…
