We review the properties of quarkonia under strong magnetic fields. The main phenomena are (i) mixing between different spin eigenstates, (ii) quark Landau levels and deformation of wave function, (iii) modification of Q̄Q potential, and (iv) the motional Stark effect. For theoretical approaches, we review (i) constituent quark models, (ii) effective Lagrangians, (iii) QCD sum rules, and (iv) holographic approaches.

In this paper, we review recent progress toward understanding the nature of quarkonia in the quark gluon plasma. We review the theory necessary to understand the melting of bound states due toExpand
QCD string breaking in strong magnetic field
At sufficiently large separation between a quark and an antiquark the quantum chromodynamics (QCD) string breaks into parts due to creation of light quark–antiquark pairs. We show that a backgroundExpand
Colour deconfinement and quarkonium binding
At high temperatures, strongly interacting matter becomes a plasma of deconfined quarks and gluons. In statistical quantum chromodynamics, deconfinement and the properties of the resultingExpand
Meson deformation by magnetic fields in lattice QCD
We study light meson properties in a magnetic field, focusing on a charged pion and a charged and polarized rho meson, in lattice QCD. The gauge-invariant density-density correlators are calculatedExpand
The ρ and A mesons in strong abelian magnetic field in SU(2) lattice gauge theory
Abstract We calculated correlators of vector, axial and pseudoscalar currents in external strong abelian magnetic field according to SU ( 2 ) gluodynamics. The masses of neutral ρ and A mesons withExpand
Majorana flipping of quarkonium spin states in transient magnetic field
We demonstrate that spin flipping transitions occur between various quarkonium spin states due to transient magnetic field produced in non central heavy ion collisions (HICs). The inhomogeneousExpand
Novel quantum phenomena induced by strong magnetic fields in heavy-ion collisions
AbstractThe relativistic heavy-ion collisions create both hot quark–gluon matter and strong magnetic fields, and provide an arena to study the interplay between quantum chromodynamics and quantumExpand
Heavy quark potential in a static and strong homogeneous magnetic field
We have investigated the properties of quarkonia in a thermal QCD medium in the background of strong magnetic field. For that purpose, we employ the Schwinger proper-time quark propagator in theExpand
Magnetic polarizability of pion
We explore the energy dependence of π mesons off the background Abelian magnetic field on the base of quenched SU(3) lattice gauge theory and calculate the magnetic dipole polarizability of chargedExpand
Magnetic polarizabilities of light mesons in SU(3) lattice gauge theory
We investigate the ground state energies of neutral pseudoscalar and vector meson in SU(3)SU(3) lattice gauge theory in the strong abelian magnetic field. The energy of ρ0ρ0 meson with zero spinExpand
