Mini - symposium Title

MS007  Computational Materials With Negative Characteristics


Material properties, such as elastic modulus, Poisson’s ratio, mass density, electric permittivity, magnetic permeability, thermal conductivity, heat capacity or others, are so defined that they are in general greater than zero. When materials exhibit negative characteristics, several physical considerations, such as violation of conservation laws in the non-Hermitian, non-reciprocal systems, or odd elasticity, are in order to examine their stability or exceptional points, where eigenvalues change from real to complex numbers. Possible applications of materials with negative characteristics are abundant, such as vibration and noise reduction, cloaking in electromagnetic, acoustical or thermomechanical fields, or unbounded effective material properties in composites. In this minisymposium, all computational aspects in understanding materials with negative characteristics are welcome, including, but not limited to, machine learning techniques to generate material microstructures, and novel computational methods in calculating physical properties for materials in solid, liquid or other states. Experimental or theoretical studies to correlate numerical results are also welcome.
