## What is/are Crossover Transition?

Crossover Transition - The variable-temperature EPR measurement confirmed a gradual spin-crossover transition (S = 5/2 ↔ S = 1/2).^{[1]}Lattice simulations indicate that EWSB in the Standard Model (SM) occurs through a crossover transition, while the presence of new physics beyond the SM could alter this thermal history.

^{[2]}Above the crossover transition, Rmax, per dsDNA molecule dropped rapidly as f-1/2 towards a planarlike monolayer.

^{[3]}The impact of first order and crossover transitions is also examined.

^{[4]}In this contribution, we discuss the mapping of the black hole model in the QCD phase diagram and show that the crossover transition, between hadrons and the quark-gluon plasma, ends in a critical point where a first order line begins.

^{[5]}The chiral transition behaviors are investigated in the improved soft-wall AdS/QCD model with the solved gravitational background, and the crossover transition can be realized.

^{[6]}Conclusions: The observation of crossover transitions positioned the isomeric high-spin level of $^{198}$At at an excitation energy of 265(3) keV.

^{[7]}A pressure-induced metallization along with a Co2+ high-spin (S = 3/2) to low-spin (S = 1/2) crossover transition is observed at high pressure near 70 GPa.

^{[8]}The studied compounds are shown to be capable of undergoing thermally initiated stepwise or synchronized spin-crossover transitions, in particular involving all the electromeric forms.

^{[9]}The collision energy dependent buildup of the 2D percolation clusters defines the temperature range $159\ifmmode\pm\else\textpm\fi{}9\text{ }\text{ }\mathrm{MeV}$ of the crossover transition between hadrons to the QGP in reasonable agreement with the lattice quantum chromodynamics (LQCD) pseudocritical temperature value of $155\ifmmode\pm\else\textpm\fi{}9\text{ }\text{ }\mathrm{MeV}$.

## critical end point

It is shown that the critical end point (CEP) linking the crossover transition with the first-order phase transition still exists and locates at $(\mu_B, T_c) \simeq (390 MeV, 145 MeV)$.^{[1]}With the increase of the chemical potential $\mu$, the critical temperature $T_c$ descends towards zero, and the crossover transition turns into a first-order one at some intermediate value of $\mu$, which implies that a critical end point naturally exists in this improved soft-wall model.

## order phase transition

We show that when using the set of parameters thus determined, the second order phase transition line (our proxy for the crossover transition) that starts at finite temperature and zero baryon chemical potential converges to the line of first order phase transitions that starts at zero temperature and finite baryon chemical potential to determine the critical end point to lie in the region $$5.^{[1]}Studies with unimproved actions found the existence of a critical quark mass value at which the crossover transition ends on a second order phase transition and becomes first order for smaller values of the quark mass for the case of both vanishing and imaginary chemical potential.

## first order phase

We find that the critical endpoint linking the crossover transition with the first-order phase transition still exists and locates at (μB,Tc)≃(390 MeV,145 MeV), which along with the crossover line are consistent with lattice result and experimental analysis from relativistic heavy ion collisions.^{[1]}

Film thickness and microstructure critically affect the spin crossover transition of a 2D coordination polymer.^{[1]}Specifically, the addition of benzimidazole results in a re-entrant spin crossover transition, i.
