Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Existence of phase transition for percolation using the Gaussian Free Field
高斯自由 伯努利渗透 相变存在
2023/5/8
In this talk, we prove that Bernoulli percolation on graph undergoes a non-trivial phase transition if the graph has bounded degrees and random walk on the graph has a heat kernel with rapid decay. Th...
Turbo codes: the phase transition
Turbo code noise channel disordered spin model the stability threshold
2015/8/21
Turbo codes are a very efficient method for communicating reliably through a noisy channel. There is no theoretical understanding of their effectiveness. In Ref. [1] they are mapped onto a ...
The Noise-Sensitivity Phase Transition in Compressed Sensing
Approximate Message Passing Lasso Basis Pursuit Minimax Risk over Nearly- Black Objects Minimax Risk of Soft Thresholding
2015/8/20
Consider the noisy underdetermined system of linear equations: y = Ax0 + z0, with n N measurement matrix A, n < N, and Gaussian white noise z0 N(0; 2I). Both y and A are known, both x0 and z0 are...
Temperature Dependence of the Raman Intensity and the Bandwidth Close to the Order-Disorder Phase Transition in NaNO3
Raman Intensity Bandwidth NaNO3
2013/1/30
We analyze the temperature dependence of the Raman intensity using the experimental data according to a power-law formula close to the order-disorder transition (Tc = 549 K) in NaNO 3. From this analy...
Phase transition induced vertical alignment of ultrathin gallium phosphide nanowire arrays on silicon by chemical beam epitaxy
Biochemical engineering Green chemistry Sustainable chemistry Universities of Applied Sciences
2016/12/2
We demonstrate high-density heteroepitaxial growth of sub-10 nm diameter gallium phosphide (GaP) nanowire (NW) arrays on silicon (Si), using chemical beam epitaxy (CBE). The vertical alignment of GaP ...
Disorder promotes ferromagnetism: Rounding of the quantum phase transition in Sr_{1-x}Ca_xRuO_3
Disorder promotes ferromagnetism Rounding the quantum phase transition Sr_{1-x}Ca_xRuO_3
2012/2/24
The subtle interplay of randomness and quantum fluctuations at low temperatures gives rise to a plethora of unconventional phenomena in systems ranging from quantum magnets and correlated electron mat...
Interplay between a hydrodynamic instability and a phase transition: the Faraday instability in dispersions of rodlike colloids
a hydrodynamic instability a phase transition Interplay rodlike colloids
2011/9/15
Strong effects of the Faraday instability on suspensions of rodlike colloidal particles are reported through measurements of the critical acceleration and of the surface wave amplitude. We show that t...
Diffused phase transition of polycrystalline (Ba0.80Sr0.20)TiO3
Barium Strontium Titanate X-ray spectroscopy Electron microscopy
2010/1/11
The purpose of this work was to determinate the influence of the 20% Sr substitutions (in sublattice A) on changes of the character of phase transition (PT) in comparison with pure barium titanate BaT...
