Transits of the QCD critical point [PDF]

Physical Review C, 2018
We analyze the evolution of hydrodynamic fluctuations in a heavy ion collision as the system passes close to the QCD critical point. We introduce two small dimensionless parameters $\lambda$ and $\Delta_s$ to characterize the evolution.

Avoided ferromagnetic quantum critical point in CeRuPO [PDF]

, 2015
CeRuPO is a rare example of a ferromagnetic (FM) Kondo-lattice system. External pressure suppresses the ordering temperature to zero at about $p_c\approx3$ GPa.

The computation of the index of a Morse function at a critical point

International Journal of Mathematics and Mathematical Sciences, 1988
A theoretical approach in computing the index of a Morse function at a critical point on a real non-singular hypersurface V is given. As a consequence the Euler characteristic of V is computed. In the case where the hypersurface is polynomial and compact,

Superconducting Quantum Critical Point

, 1997
We study the properties of a quantum critical point which develops in a BCS superconductor when pair-breaking suppresses the transition temperature to zero. The pair fluctuations are characterized by a dynamical critical exponent z=2. Except for very low

QCD Critical Point: The Race is On [PDF]

, 2014
A critical point in the phase diagram of Quantum Chromodynamics (QCD), if established either theoretically or experimentally, would be as profound a discovery as the good-old gas-liquid critical point.

Dynamic critical phenomena at a holographic critical point

, 2011
We study time-dependent perturbations to a family of five-dimensional black hole spacetimes constructed as a holographic model of the QCD phase diagram.

Hydrodynamics with parametric slowing down and fluctuations near the critical point [PDF]

Physical Review D, 2017
The search for the QCD critical point in heavy-ion collision experiments requires dynamical simulations of the bulk evolution of QCD matter as well as of fluctuations.

Itinerant quantum critical point with fermion pockets and hotspots. [PDF]

Proc Natl Acad Sci U S A, 2019
Significance The present work summarizes major progress in research on the itinerant quantum critical point (QCP). The authors designed a model and developed quantum Monte Carlo simulation to examine itinerant QCPs generated by antiferromagnetic ...

Bootstraping the QCD Critical Point

, 2003
It is shown that hadronic matter formed at high temperatures, according to the prescription of the statistical bootstrap principle, develops a critical point at nonzero baryon chemical potential.

a -theorem for Horndeski gravity at the critical point [PDF]

Physical Review D, 2018
We study holographic conformal anomalies and the corresponding a-theorem for Einstein gravity extended with Horndeski terms that involve up to and including linear curvature tensors. We focus on our discussion in D=5 bulk dimensions.
