SYK model, chaos and conserved charge
Journal of High Energy Physics, 2017 We study the SYK model with complex fermions, in the presence of an all-to-all q-body interaction, with a non-vanishing chemical potential. We find that, in the large q limit, this model can be solved exactly and the corresponding Lyapunov exponent can ...

Investigation of chaos in a polydyne cam with flat-faced follower mechanism
Journal of King Saud University: Engineering Sciences, 2021 In this paper, the chaotic analysis is predicted based on the non-periodic motion of the follower. Non-periodic motion of the follower has been investigated by using the conception of Lyapunov exponent parameter.

The asymptotic behavior of a dynamical process coming from the development in continuous fractions [PDF]
ITM Web of Conferences, 2020 The aim of this paper is the study of a dynamical process generated by a sequence of maps: xn+1=fnxn$${x_{n + 1}} = {f_n}\left( {{x_n}} \right)$$ where fn : 0,∞ →0,∞, fn x = cn1+x for all n ∈ N and cnn$${f_n}{\rm{ : }}\left( {0,\infty } \right){\rm{ }} \

Lyapunov Exponent-Based Study of Chaotic Mechanical Behavior of Concrete under Compression
Advances in Civil Engineering, 2019 Chaos theory is advantageous in achieving a deeper understanding of the nonlinearity and randomness of concrete behavior. In this study, the experimental data of concrete under compression were examined and discussed using Lyapunov exponent. According to

Classification of Processes by the Lyapunov Exponent [PDF]
, 2005 This paper deals with the problem of the discrimination between well-predictable and not-well-predictable time series. One criterion for the separation is given by the size of the Lyapunov exponent, which was originally defined for deterministic systems.

The Cardiodynamicsgram Based Early Detection of Myocardial Ischemia Using the Lempel-Ziv Complexity
IEEE Access, 2020 Background: Electrocardiogram (ECG) is a routine method for detecting myocardial ischemia in clinical practice, but more than half of ECGs are without specific ischemic changes.
