Nuclear Binding Near a Quantum Phase Transition.
How do protons and neutrons bind to form nuclei? This is the central question of ab initio nuclear structure theory. While the answer may seem as simple as the fact that nuclear forces are attractive, the full story is more complex and interesting. In this work we present numerical evidence from ab initio lattice simulations showing that nature is near a quantum phase transition, a zero-tempera...
متن کاملPion Velocity near the Chiral Phase Transition
An enhancement of dielectron mass spectra below ρ/ω resonance observed at CERN SPS3) can be explained by the dropping mass of ρ meson4) following the Brown-Rho scaling.5) There is a scenario which certainly requires the dropping mass of the vector meson and supprots the Brown-Rho scaling, named the vector manifestation (VM)6) where the massless vector meson becomes the chiral partner of pion at...
متن کاملFluctuations near the Deconfinement Phase Transition Boundary
In this talk I discuss how a first order phase transition may proceed in rapidly expanding partonic matter produced in a relativistic heavy-ion collision. The resulting picture is that a strong collective flow of matter will lead to the fragmentation of a metastable phase into droplets. If the transition from quark-gluon plasma to hadron gas is of the first order, it will manifest itself by str...
متن کاملObservation of a near-surface structural phase transition in SrTiO3 by optical second harmonic generation
A near-surface structural phase transition on a SrTiO3 single crystal, occurring at T(*) about 45 K above the bulk cubic-to-tetragonal transition, is observed by means of optical second harmonic generation. The temperature dependence of the second harmonic field in the vicinity of T(*) is described with a phenomenological Landau-type model.
متن کاملAnisotropic lattice softening near the structural phase transition in the thermosalient crystal 1,2,4,5-tetrabromobenzene.
The thermosalient effect (crystal jumping on heating) attracts much attention as both an intriguing academic phenomenon and in relation to its potential for the development of molecular actuators but its mechanism remains unclear. 1,2,4,5-Tetrabromobenzene (TBB) is one of the most extensively studied thermosalient compounds that has been shown previously to undergo a phase transition on heating...
