Spin-orbiton and quantum criticality in FeSc2S4 [PDF]
, 2015 In FeSc2S4 spin-orbital exchange competes with strong spin-orbit coupling, suppressing long-range spin and orbital order and, hence, this material represents one of the rare examples of a spin-orbital liquid ground state.

Jamming Criticality Revealed by Removing Localized Buckling Excitations
Physical Review Letters, 2015 Recent theoretical advances offer an exact, first-principle theory of jamming criticality in infinite dimension as well as universal scaling relations between critical exponents in all dimensions. For packings of frictionless spheres near the jamming transition, these advances predict that nontrivial power-law exponents characterize the critical ...

Excitation Energy as a Basic Variable to Control Nuclear Disassembly [PDF]
, 1999 Thermodynamical features of Xe system is investigated as functions of temperature and freeze-out density in the frame of lattice gas model. The calculation shows different temperature dependence of physical observables at different freeze-out density. In

Critical excitation-inhibition balance in dense neural networks [PDF]
Physical Review E, 2019 The "edge of chaos" phase transition in artificial neural networks is of renewed interest in light of recent evidence for criticality in brain dynamics. Statistical mechanics traditionally studied this transition with connectivity $k$ as the control parameter and an exactly balanced excitation-inhibition ratio.

Evidence for Two Time Scales in Long SNS Junctions
, 2009 We use microwave excitation to elucidate the dynamics of long superconductor / normal metal / superconductor Josephson junctions. By varying the excitation frequency in the range 10 MHz - 40 GHz, we observe that the critical and retrapping currents ...

Excitation spectra in crystal plasticity [PDF]
, 2017 Plastically deforming crystals exhibit scale-free fluctuations that are similar to those observed in driven disordered elastic systems close to depinning, but the nature of the yielding critical point is still debated.

Analysis of dynamic stability of nonlinear suspension
Advances in Mechanical Engineering, 2018 The vehicle is excited by the road surface while traveling. The vehicle suspensions play a significant role not only in damping out the vibrations created due to the excitation but also in maintaining the stability of the entire system.

Field-angle anisotropy of proximate Kitaev systems under an in-plane magnetic field
Physical Review Research, 2021 We have investigated the field-angle behaviors of magnetic excitations under an in-plane magnetic field for proximate Kitaev systems. By employing the exact diagonalization method in conjunction with the linear spin wave theory, we have demonstrated that

Propagation failure of excitation waves on trees and random networks
, 2014 Excitation waves are studied on trees and random networks of coupled active elements. Undamped propagation of such waves is observed in those networks. It represents an excursion from the resting state and a relaxation back to it for each node.
