Delocalized nonlinear vibrational modes and their effect on the properties of binary NiTi alloy [PDF]
The purpose of this work is to investigate the behavior of stable one-component delocalized nonlinear vibrational modes in simple cubic titanium and nickel sublattices, as well as their influence on the properties of the binary NiTi alloy. Methods.

Classical Limit for Scalar Fields at High Temperature [PDF]
We study real-time correlation functions in scalar quantum field theories at temperature $T=1/\beta$. We show that the behaviour of soft, long wavelength modes is determined by classical statistical field theory.

Blade crack will cause severe mistuning of hard-coated blisks, which will lead to vibration localization. To identify crack mistuning and analyze influence factors, in this study, a mistuning identification method of blade cracks in hard-coated blisks is

Lyapunov Modes and Time-Correlation Functions for Two-Dimensional Systems [PDF]
The relation between the Lyapunov modes (delocalized Lyapunov vectors) and the momentum autocorrelation function is discussed in two-dimensional hard-disk systems. We show numerical evidence that the smallest time-oscillating period of the Lyapunov modes

Head-Positioning Control Using Virtual Resonant Modes in a Hard Disk Drive
In conventional control systems in hard disk drives, it is difficult to compensate for disturbances above the primary mechanical resonance. In this paper, a design method that uses a virtual resonant mode in head-positioning systems of hard disk drives ...

Softest elastic mode governs materials hardness
Single-crystal elastic constants and mechanical hardness of covalent and ionic crystals have been studied using first-principles calculations. The results show that the hardness is dominated by the softest elastic mode, not by the averaged elastic moduli as generally assumed.

Parametric resonance at the critical temperature in high energy heavy ion collisions [PDF]
Parametric resonance in soft modes at the critical temperature ($T_{c}$) in high energy heavy ion collisions is studied in the case when the temperature ($T$) of the system is almost constant for a long time. By deviding the fields into three parts, zero
