Critical dynamical fluctuations near the QCD critical point

open access: yesHe jishu, 2023
The exploration of the critical point on the QCD (Quantum Chromodynamics) phase diagram is one of the most important goals of the beam energy scan program in relativistic heavy-ion collisions (RHIC-BES).

CRASHES AS CRITICAL POINTS [PDF]

open access: yesInternational Journal of Theoretical and Applied Finance, 2000
We study a rational expectation model of bubbles and crashes. The model has two components: (1) our key assumption is that a crash may be caused by local self-reinforcing imitation between noise traders. If the tendency for noise traders to imitate their nearest neighbors increases up to a certain point called the "critical" point, all noise traders ...

Is Seismicity Operating at a Critical Point? [PDF]

open access: yesPhysical Review Letters, 2021
Seismicity and faulting within the Earth crust are characterized by many scaling laws that are usually interpreted as qualifying the existence of underlying physical mechanisms associated with some kind of criticality in the sense of phase transitions.

Relative Critical Points [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
Relative equilibria of Lagrangian and Hamiltonian systems with symmetry are critical points of appropriate scalar functions parametrized by the Lie algebra (or its dual) of the symmetry group. Setting aside the structures - symplectic, Poisson, or variational - generating dynamical systems from such functions highlights the common features of their ...

Some multiplicity results to the existence of three solutions for a dirichlet boundary value problem involving the p-laplacian

open access: yesMathematical Modelling and Analysis, 2011
In this paper we prove the existence of two intervals of positive real parameters λ for a Dirichlet boundary value problem involving the p-Laplacian which admit three weak solutions, whose norms are uniformly bounded with respect to λ belonging to one of
