A ferrofluid is a colloidal mixture of magnetic particles and a solvent with the addition of surfactant to keep the particles dispersed. Such
fluids can exhibit highly paramagnetic behavior, including extreme deformation of the fluid along applied external magnetic field lines. A
ferromagnetic ferrofluid has not been produced until recently. Mertelj et al. have reported that a mixture of plate-like magnetic particle in a Liquid Crystal (LC) solvent, demonstrates the ferromagnetic properties of spontaneous magnetization and hysteresis.
Superselection rules forbid certain coherent quantum superpositions. However, superposition rules can be circumvented by consuming
appropriate frameness resources, namely, quantum systems whose states are asymmetric with respect to a group G of transformations associated
with the requisite frame of reference. In the representation, we review the paper by Michael Skotiniotis et al. that develops a theory of charge-paritytime (CPT) frameness resources to circumvent CPT superselection.
