Parametric resonance at the critical temperature in high energy heavy ion collisions [PDF]

, 2001
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

Soft Modes in Undercooled Liquids [PDF]

Europhysics News, 1993
Abstract Recent studies of soft vibrational, tunneling and relaxational modes in glasses support the validity of the soft potential model, an extension of the tunneling model. The implications of this validity are investigated for the undercooled liquid.

Multiple Soft-Mode Vibrations of Lead Zirconate [PDF]

Physical Review Letters, 2014
Polarized Raman, IR and time-domain THz spectroscopy of orthorhombic lead zirconate single crystals yielded a comprehensive picture of temperature-dependent quasiharmonic frequencies of its low-frequency phonon modes. It is argued that these modes primarily involve vibration of Pb and/or oxygen octahedra librations and their relation to particular ...

Hybrid intelligent system for a synchronous rectifier converter control and soft switching ensurement

Engineering Science and Technology, an International Journal, 2022
This research implements an intelligent control strategy in a synchronous rectifier buck converter to assure that the converter operates in soft-switching mode. The converter is analysed and the two different switching modes are presented: Hard-switching

Critical fluctuations of QCD phase transitions and their related observables [PDF]

EPJ Web of Conferences, 2022
We study how the dilepton production rate and the electric conductivity are affected by the soft modes inherently associated with the second-order phase transitions at the critical temperature of color superconductivity and QCD critical point.

Classical Fields Near Thermal Equilibrium [PDF]

, 1996
We discuss the classical limit for the long-distance (``soft'') modes of a quantum field when the hard modes of the field are in thermal equilibrium.
