Theoretical Approaches

We study the properties of the deconfining phase transition for a finite-volume system in which the hadronic and quark–gluon plasma phases coexist and the finite extensions of the hadrons are taken into account. Finite-size effects are examined by probing the behavior of some useful response functions near the transition, and scaling exponents are determined using a finite-size scaling (FSS) analysis. For the shift scaling exponent, the finite-size transition point is determined from several definitions, and we propose new ways of defining this quantity, using cumulants of the probability distribution. Our study shows that the deconfining phase transition stays first-order, the scaling exponents being equal to unity. This result is consistent with the predictions of the standard FSS theoretical approaches to a first-order phase transition, and with results using Monte Carlo methods in lattice QCD and other models in statistical physics.

Photon Blockade

We prove that the observable telegraph signal accompanying the bistability in the photon-blockade-breakdown regime of the driven and lossy Jaynes–Cummings model is the finite-size precursor of what in the thermodynamic limit is a genuine first-order phase transition. We construct a finite-size scaling of the system parameters to a well-defined thermodynamic limit, in which the system remains the same microscopic system, but the telegraph signal becomes macroscopic both in its timescale and intensity. The existence of such a finite-size scaling completes and justifies the classification of the photon-blockade-breakdown effect as a first-order dissipative quantum phase transition.

We report an organic–ionic material that undergoes a first-order structural phase transition, induced by order–disorder of oxygen atoms in picrate anion. This strategy offers a potential pathway to explore new switchable dielectric materials.
