Evolution of the quantum phase transitions in XXY general spin trimers with applied magnetic field and variable exchange parameters

This study investigates the thermodynamics and magnetic excitations of XXY general spin isosceles quantum trimers with a variable magnetic field and exchange parameters. Using an isotropic Heisenberg Hamiltonian, we analyze how the energy eigenstates, heat capacities, and magnetic susceptibilities evolve in mixed asymmetric systems of with exchange parameters of αJ1 and J2). Our analysis of these states' evolution allows us to map out the quantum phase transitions in these spin systems. From our findings, we hope to provide further insight into the general understanding of molecular magnet systems with an increase in different parameters and useful characterization methods of experimental investigations of molecular magnets and spin clusters.
