Continuum model for the terahertz dielectric response of glasses
Tatsuya Mori, Hideyuki Mizuno, Yuzuki Motokawa +6
Boson peak dynamics in glasses produce a robust crossover in the terahertz (THz) dielectric response that standard Debye or Lorentz models do not capture. We develop a continuum de…
Boson peak in the dynamical structure factor of network- and packing-type glasses
Hideyuki Mizuno, Emi Minamitani
Glasses are structurally disordered solids that host, in addition to crystalline-like phonons, vibrational excitations with no direct phononic counterpart. A long-standing universa…
Relationship between the boson peak and first sharp diffraction peak in glasses
Dan Kyotani, Soo Han Oh, Suguru Kitani +10
Boson peak (BP) dynamics refers to the universal excitation in the terahertz region of glass. In this study, the universal dynamics of BP were quantitatively evaluated in various g…
Persistent homology elucidates hierarchical structures responsible for mechanical properties in covalent amorphous solids
Emi Minamitani, Takenobu Nakamura, Ippei Obayashi +1
Understanding how atomic-level structures govern the mechanical properties of amorphous materials remains a fundamental challenge in solid-state physics. Under mechanical loading,…
Mechanical Responses and Stress Fluctuations of a Supercooled Liquid in a Sheared Non-Equilibrium State
Hideyuki Mizuno, Ryoichi Yamamoto
A steady shear flow can drive supercooled liquids into a non-equilibrium state. Using molecular dynamics simulations under steady shear flow superimposed with oscillatory shear str…
