Fermion-induced quantum criticality with two length scales in Dirac systems The quantum phase transition to a Z(3)-ordered Kekule valence bond solid in two-dimensional Dirac semimetals is governed by a fermion-induced quantum critical point, which renders the putatively discontinuous transition continuou...
Here, the main issue relates with two length scales that are size and the coherence length of the puddles. It has been shown that the energy scale related to the rare-ordered region falls exponentially with the size of the droplet which leads to the singular density of states for anomalously...
Fractal lattices are self-similar structures with repeated patterns on different scales. Quantum transport through such structures is subtle due to the possible co-existence of localized and extended states. Here, we study the dynamical properties of two fractal lattices, the Sierpiński gasket and the...
Beyond advancing the DQC scenario, our scaling approach provides a new window into out-of-equilibrium criticality with multiple length and time scales.doi:10.1038/s41467-025-58477-zYu-Rong Shuhttps://ror.org/05ar8rn06grid.411863.90000 0001 0067 3588School of Physics and Materials ScienceGuangzhou...
The ratio of the two determines the dimensionless coupling constant for spin-fermion interaction λ2 ∝ g/ωsf. We show that λ scales with the spin correlation length and diverges at criticality. This divergence implies that the conventional perturbative expansion breaks down. We develop a novel ...

There are two explicit length scales in this problem: the zero of r(x), x 0 = L(−r 0 /2) 1/n , and the bare cor- relation length ξ 0 =−c/r 0 . One expects the phase transition to occur when x 0 =ξ 0 (apart from a factor of O(1)). This condition leads to ...
There could be immediate implications for quantum memory and also in quantum neurobiology in substantiating the conceptualization of neural signaling as a criticality triggered phase transition. The consideration of system extremes is a method also being applied, for example, to find new matter phases ...
(π-electrons) in the EM brain. The strategy of examining criticality in magnetic chaotic systems depends on the idea to relate scale transformations to changes in the temperature (renormalization). Two main attractors are corresponding toT=0 andT=∞, and the boundary between these two domains ...
