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).

Disorder-induced critical exponents near a ferromagnetic quantum critical point in Mn1−xCrxSi [PDF]

open access: yes, 2020
We report the observation of critical behavior in Mn1−xCrxSi (0≤x≤1) close to a T = 0 K quantum critical point, consistent with the Belitz-Kirkpatrick-Vojta (BKV) theory of disordered metallic ferromagnets.

Multiple Periodic Solutions for Odd Perturbations of the Discrete Relativistic Operator

open access: yesMathematics, 2022
We obtain the existence of multiple pairs of periodic solutions for difference equations of type −Δ(Δu(n − 1)1 − |Δu(n − 1)|2)=λg(u(n))(n∈Z), where g:R→R is a continuous odd function with anticoercive primitive, and λ>0 is a real parameter.

Field-Induced Quantum Critical Point in CeCoIn5 [PDF]

open access: yes, 2003
The resistivity of the heavy-fermion superconductor CeCoIn5 was measured as a function of temperature, down to 25 mK and in magnetic fields of up to 16 T applied perpendicular to the basal plane. With increasing field, we observe a suppression of the non-

Local Shape of the Vapor–Liquid Critical Point on the Thermodynamic Surface and the van der Waals Equation of State

open access: yesFrontiers in Physics, 2021
Differential geometry is a powerful tool to analyze the vapor–liquid critical point on the surface of the thermodynamic equation of state. The existence of usual condition of the critical point (∂p/∂V)T=0 requires the isothermal process, but the ...

On a new critical point theorem and some applications to discrete equations [PDF]

open access: yesOpuscula Mathematica, 2014
Using the Fenchel-Young duality we derive a new critical point theorem. We illustrate our results with solvability for certain discrete BVP. Multiple solutions are also considered.
