The stress relaxation dynamics of a La 60 Ni 15 Al 25 metallic glass were studied in ribbon and bulk samples. In both tensile and single cantilever testing modes, it is observed that the …

Ergodicity, a fundamental concept in statistical mechanics, is not yet a fully understood phenomena for closed quantum systems, particularly its connection with the underlying …
We investigate both analytically and numerically the dynamics of quantum scrambling, characterized by out-of-time ordered correlators (OTOCs), in a non-Hermitian quantum …

We study a large-N bosonic quantum mechanical sigma-model with a spherical target space subject to disordered interactions, more colloquially known as the p-spin spherical model …
We study the dynamics of a quantum $ p $-spin glass model starting from initial states defined in microcanonical shells, in a classical regime. We compute different chaos …
Many-body systems which saturate the quantum bound on chaos are attracting interest across a wide range of fields. Notable examples include the Sachdev-Ye-Kitaev model and …

The surrounding reality can be analyzed due to the interaction of complex nonlinear dynamic systems. The article's main objective is to develop and analyze the models that best …
We make lattice generalization of two well-known zero-dimensional models of quantum spin glass, Sachdev-Ye (SY) and spherical quantum p-spin glass model, to one dimension for …
