We discuss general properties and possible types of magnetic vortices in non-Abelian gauge theories (we consider here G = SU(N), SO(N), USp(2N)) in the Higgs phase. The sources of such vortices carry “fractional” quantum numbers such as Zn charge (for SU(N)), but also full non-Abelian charges of the dual gauge group. If such a model is re-interpreted as an effective dual magnetic theory of the ...

Vortices play a crucial role in determining the properties of superconductors as well as their applications. Therefore, characterization and manipulation of vortices, especially at the single-vortex level, is of great importance. Among many techniques to study single vortices, scanning tunnelling microscopy (STM) stands out as a powerful tool, due to its ability to detect the local electronic s...

Quantum vortices are often endowed with an effective inertial mass, due, for example, to massive particles in their cores. Such ``massive vortices'' display new phenomena beyond the standard picture of superfluid vortex dynamics, where mass is neglected. In this work, we demonstrate that allowed collide, as opposed massless counterparts. We propose a scheme generate controllable, repeatable, de...

– Bohmian mechanics is a causal interpretation of quantum mechanics in which particles describe trajectories guided by the wave function. The dynamics in the vicinity of nodes of the wave function, usually called vortices, is regular if they are at rest. However, vortices generically move during time evolution of the system. We show that this movement is the origin of chaotic behavior of quantu...

We examine spin vortices in ferromagnetic quantum Heisenberg models with planar anisotropy on two–dimensional lattices. The symmetry properties and the time evolution of vortices built up from spin–coherent states are studied in detail. Although these states show a dispersion typical for wave packets, important features of classical vortices are conserved. Moreover, the results on symmetry prop...

We study properties of Z–vortices in the crossover region of the 3D SU(2) Higgs model. Correlators of the vortex currents with gauge field energy and Higgs field squared (“quantum vortex profile”) reveal a structure that can be compared with a classical vortex. We define a core size and a penetration depth from the vortex profile. Z–vortices are found to interact with each other analogously to ...

Quantized vortices are key features of quantum fluids such as superfluid helium and Bose-Einstein condensates. The reconnection of quantized vortices and subsequent emission of Kelvin waves along the vortices are thought to be central to dissipation in such systems. By visualizing the motion of submicron particles dispersed in superfluid (4)He, we have directly observed the emission of Kelvin w...

A class of topological excitations-the odd-winding number vortices-in a spinless 2D chiral p-wave (px+ipy) superconductor traps Majorana fermion states in the vortex cores. For a dilute gas of such vortices, the lowest energy fermionic eigenstates are intrinsically nonlocal. We predict two testable signatures of this unusual quantum nonlocality in quasiparticle tunneling experiments. We discuss...

• The free energy F displays the same “flux regeneration effect” in a cylindrical geometry under the protocol described in Ref 6, and represents a simple way of understanding the effect. Indeed, this effect requires the enhanced stability of hc/e vortices discussed here, for otherwise hc/2e vortices generated by thermal or quantum fluctuations as one moves into the normal state will annihilate ...
