Supersolidity around a Critical Point in Dipolar Bose-Einstein Condensates. [PDF]
Physical Review Letters, 2019 We explore spatial symmetry breaking of a dipolar Bose-Einstein condensate in the thermodynamic limit and reveal a critical point in the phase diagram at which crystallization occurs via a second-order phase transition.

Search for the QCD critical point with fluctuations of conserved quantities in relativistic heavy-ion collisions at RHIC: an overview [PDF]
Nuclear Science and Techniques, 2017 Fluctuations of conserved quantities, such as baryon, electric charge, and strangeness number, are sensitive observables in relativistic heavy-ion collisions to probe the QCD phase transition and search for the QCD critical point.

Hidden magnetism at the pseudogap critical point of a cuprate superconductor [PDF]
Nature Physics, 2019 The nature of the pseudogap phase of hole-doped cuprate superconductors is still not understood fully. Several experiments have suggested that this phase ends at a critical hole doping level p *, but the nature of the ground state for lower doping is ...

Singular charge fluctuations at a magnetic quantum critical point [PDF]
Science, 2018 Spin-charge entanglement Many physical properties follow characteristic scaling laws near quantum critical points, which are associated with phase transitions at absolute zero temperature.

QCD equation of state matched to lattice data and exhibiting a critical point singularity [PDF]
Physical Review C, 2018 We construct a family of equations of state for QCD in the temperature range 30MeV≤T≤800MeV and in the chemical potential range 0≤μB≤450MeV. These equations of state match available lattice QCD results up to O(μB4) and in each of them we place a critical

International Journal of Mathematics and Mathematical Sciences, 2002 Let H be a Hilbert space such that H=V⊕W, where V and W are two closed subspaces of H. We generalize an abstract theorem due to Lazer et al. (1975) and a theorem given by Moussaoui (1990-1991) to the case where V and W are not necessarily finite ...

Deconfined Quantum Critical Points [PDF]
Science, 2004 The theory of second-order phase transitions is one of the foundations of modern statistical mechanics and condensed-matter theory. A central concept is the observable order parameter, whose nonzero average value characterizes one or more phases. At large distances and long times, fluctuations of the order parameter(s) are described by a continuum ...

Dynamical signature of fractionalization at a deconfined quantum critical point [PDF]
Physical review B, 2018 Author(s): Ma, N; Sun, GY; You, YZ; Xu, C; Vishwanath, A; Sandvik, AW; Meng, ZY | Abstract: © 2018 American Physical Society. Deconfined quantum critical points govern continuous quantum phase transitions at which fractionalized (deconfined) degrees of ...

A Possible Universe in Pulsation by Using a Hydro-Dynamical Model for Gravity [PDF]
INCAS Bulletin, 2016 By using a hydro-dynamical model for gravity previously given by the author, a pulsating universe is possible to describe. This is possible because two hydro-dynamical sources are in attraction both when they are emitting and absorbing fluid.

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.
