## Multistep Bloch-line-mediated Walker breakdown in ferromagnetic strips

By Johanna Hütner, Touko Herranen, and Lasse Laurson from Recent Articles in Phys. Rev. B. Published on May 24, 2019.

Author(s): Johanna Hütner, Touko Herranen, and Lasse Laurson

A well-known feature of magnetic field driven dynamics of domain walls in ferromagnets is the existence of a threshold driving force at which the internal magnetization of the domain wall starts to precess—a phenomenon known as the Walker breakdown—resulting in an abrupt drop of the domain-wall prop...

Author(s): I. Esterlis, S. A. Kivelson, and D. J. Scalapino

Thermodynamic properties of the square-lattice Holstein model of the electron-phonon problem with phonon frequencies small compared to the bare Fermi energy are obtained using Monte Carlo methods, a strong-coupling (bipolaronic) expansion, and a weak-coupling Migdal-Eliashberg approach. Already at e...

## On the origin of the anomalous peak in the resistivity of ${\mathrm{TiSe}}_{2}$

By Matthew D. Watson, Adam M. Beales, and Philip D. C. King from Recent Articles in Phys. Rev. B. Published on May 23, 2019.

Author(s): Matthew D. Watson, Adam M. Beales, and Philip D. C. King

Resistivity measurements of TiSe${}_{2}$ typically show a pronounced and broad peak upon cooling, whose link with the much-studied charge density wave like transition that this material hosts has proved controversial. Here, the authors present quantitative simulations of resistivity using a simple model, but one whose parameters are strongly constrained from recent electronic structure measurements. It is shown that the prominent peak in resistivity, and its variation with doping, arise due to changing thermal carrier populations of a narrow-gap semiconductor, and that these are largely unrelated to the 200 K phase transition.

## Spontaneous symmetry breaking at surfaces of $d$-wave superconductors: Influence of geometry and surface ruggedness

Author(s): P. Holmvall, A. B. Vorontsov, M. Fogelström, and T. Löfwander

Surfaces of $d$-wave superconductors may host a substantial density of zero-energy Andreev states. The zero-energy flat band appears due to a topological constraint, but comes with a cost in free energy. We have recently found that an adjustment of the surface states can drive a phase transition int...

Remarkably, any operation in the braid group can ...

Author(s): Stefania Gori, Stefano Profumo, and Bibhushan Shakya

Imaging Atmospheric Cherenkov telescope (IACT) searches for dark matter often perform observations in “wobble mode,” i.e., simultaneously collecting data from the signal region and from a corresponding background control region. This observation strategy is possibly compromised in scenarios where da...

Topological phases of matter that have been recently extended to topological phases of sound can confine acoustic energy at the corners of higher-order topological insulators. We broaden this concept by incorporating parity-time symmetry and show new topologically protected confinement rules that ar...
