Zr isotopes as a region of intertwined quantum phase transitions

چکیده
The zirconium isotopes with $A=92--110$ have one of the most complicated evolution structure in nuclear chart. In order to understand structural these isotopes, we carry a detailed calculation definite symmetry-based framework, interacting boson model configuration mixing (IBM-CM). We compare our large range experimental data, such as energy levels, two-neutron separation energies, $E2$ and $E0$ transition rates, isotope shifts, magnetic moments. low lying spectra is explained using notion intertwined quantum phase transitions (IQPTs), for which QPT involving crossing two configurations (Type II) accompanied by shape each separately I). study, find occurrence Type I within intruder configuration, changing from weakly deformed prolate finally $\ensuremath{\gamma}$-unstable, associated U(5), SU(3) SO(6) dynamical symmetry limits IBM, respectively. Alongside QPT, also II between normal configurations, where both Types critical point near $A\ensuremath{\approx}100$. good agreement vast empirical data along chain demonstrates relevance IQPTs can serve case study set path new investigations other nuclei physical systems.

Continuous Quantum Phase Transitions
A quantum system can undergo a continuous phase transition at the absolute zero of temperature as some parameter entering its Hamiltonian is varied. These transitions are particularly interesting for, in contrast to their classical finite temperature counterparts, their dynamic and static critical behaviors are intimately intertwined. We show that considerable insight is gained by considering t...

whereM is a real, symmetric, positive-definite matrix (i.e. all eigenvalues are positive). This identity can be easily established by changing variables of integration to a basis in which M is diagonal. We will use this identity to compute the free energy density F , defined by Z = exp(−V F ) where V is the volume of spacetime. In the paramagnetic phase, r > 0, the perturbative expansion for F ...

U nderstanding matter—a collection of many interacting constituents, such as atoms and electrons—is a major endeavor in physics. While most studies in this field have focused on matter that is in thermal equilibrium with its environment, many phenomena occurring in nature involve matter out of equilibrium. The reason for this disparity may lie in the often-repeated observation that, to paraphra...
