Topological Stability of Kinetic $k$-Centers [PDF]
We study the $k$-center problem in a kinetic setting: given a set of continuously moving points $P$ in the plane, determine a set of $k$ (moving) disks that cover $P$ at every time step, such that the disks are as small as possible at any point in time ...

Topological Classification and Stability of Fermi Surfaces [PDF]
In the framework of the Cartan classification of Hamiltonians, a kind of topological classification of Fermi surfaces is established in terms of topological charges.

Stability of Topological Black Holes [PDF]
We explore the classical stability of topological black holes in d-dimensional anti-de Sitter spacetime, where the horizon is an Einstein manifold of negative curvature.

Stabilizing topological superfluidity of lattice fermions [PDF]
Attractive interaction between spinless fermions in a two-dimensional lattice drives the formation of a topological superfluid. But the topological phase is dynamically unstable towards phase separation when the system has a high density of states and large interaction strength.

Topological bulk solitons in a nonlinear photonic Chern insulator
The combination of nonlinearity and topology has recently attracted significant attention in the field of optical physics. This work considers a photonic Chern insulator in the nonlinear regime and explores the properties of topological bulk solitons ...

We present a discussion of embedded vortices in general Yang-Mills theories. The origin of a family structure of solutions is shown to be group theoretic in nature and a procedure for its determination is developed.

Stability of topological wall defects on spheres with n-atic order
Topological point defects on orientationally ordered spheres and on deformable fluid vesicles have been investigated, partly motivated by their potential applications in creating superatoms with directional bonds through functionalization of the “bald ...

Stability of bicalicene isomers: A topological study [PDF]
Bicalicene is the conjugated hydrocarbon obtained by joining two calicene fragments. This can be done in two different ways, thus resulting in two bicalicene isomers (tentatively referred to as cis and trans).

Topological Susceptibility and Zero Mode Size in Lattice QCD [PDF]
We use the overlap formalism to define a topological index on the lattice. We study the spectral flow of the hermitian Wilson-Dirac operator and identify zero crossings with topological objects.

Driven-dissipative topological phases in parametric resonator arrays [PDF]
We study the phenomena of topological amplification in arrays of parametric oscillators. We find two phases of topological amplification, both with directional transport and exponential gain with the number of sites, and one of them featuring squeezing ...
