Quantum vortex phases of charged pion condensates induced by rotation in a magnetic field
arxiv(2024)
摘要
Using the relativistic complex scalar field model with a repulsive
self-interaction, we discuss the ground state structure of charged pion
condensation under the coexistence of parallel rotation and magnetic field. Our
previous study found that the density distribution profile of the condensates
is a supergiant quantum vortex phase and change with rotational speed and
coupling constant. In this work, we further discover vortex lattice structures
in the condensates under conditions of small rotation and strong coupling
constant. This mechanism can be thought of as electrical superconductivity:
Vortex lattices are created to better adapt to changes in rotation and
interaction. Furthermore, large rotation and weak coupling constant are more
likely to cause the vortex lattices to be destroyed and form a giant quantum
vortex similar to a doughnut. We expect this phenomenon can be observed in the
relativistic non-central heavy ion collisions with large rotation and strong
magnetic field.
