The human brain, unlike the rapid pace of cultural and technological change, is the product of long evolutionary processes shaped over millions of years within a hunter–gatherer context. Most of our cognitive, emotional, and social mechanisms evolved for life in small, mobile, and environmentally embedded groups—not for existence in today’s dense, complex urban societies. This mismatch between our evolved mind and the modern world underlies many of the behavioral patterns and psychological conflicts characteristic of contemporary life.

Drawing on findings from evolutionary psychology, neuroscience, and behavioral archaeology, this talk explores how ancient adaptations—such as fear, aggression, empathy, food preferences, and social tendencies—manifest themselves in modern contexts, often in maladaptive ways. For instance, the ancestral craving for sugar and fat, once a survival strategy in food-scarce environments, now contributes to global health issues; likewise, our deep-seated desire for social validation finds new expression in the dynamics of social media.

The goal of this talk is not to romanticize the past but to illuminate the evolutionary legacy that continues to shape human behavior. By understanding the prehistoric architecture of our minds, we can better interpret our motivations, biases, and challenges in the modern age. To understand the hunter–gatherer mind, ultimately, is to understand ourselves.

Abstract:

In this presentation, I will discuss generalized parton distributions (GPDs) and their central role in probing the nucleon’s internal structure. I will review some important physical processes involving GPDs and briefly explain the theoretical and phenomenological framework used to extract them through QCD analyses of experimental data. I will also highlight recent developments from the MMGPDs Collaboration, emphasizing new constraints on GPDs and their implications for our understanding of nucleon structure.

We investigate the sensing capacity of non-equilibrium dynamics in quantum systems exhibiting Bloch oscillations. By focusing on the resource efficiency of the probe, quantified by quantum Fisher information, we find different scaling behaviors in two different phases, namely localized and extended. Our results provide a quantitative ansatz for quantum Fisher information in terms of time, probe size, and the number of excitations. In the long-time regime, the quantum Fisher information is a quadratic function of time, touching the Heisenberg limit. The system size scaling drastically depends on the phase changing from quantum-enhanced scaling in the extended phase to size-independent behavior in the localized phase. Furthermore, increasing the number of excitations always enhances the precision of the probe, although, in the interacting systems the enhancement becomes less eminent than the non-interacting probes. This is due to the induced localization by increasing the interaction between the excitations. We show that a simple particle configuration measurement together with a maximum likelihood estimation can closely reach the ultimate precision limit in both single- and multi-particle probes.

An oriented k-uniform hypergraph (a family of ordered k-sets) has Property O if, for every total order of its vertices, there exists an edge whose orientation is consistent with that order. In contrast, the Erdos-Szekeres Property concerns pairs of orders: for two linear orders <_1 and <_2 on a vertex set V, there exists a k-subset e \subset V that is monotone with respect to both, meaning that <_1 and <_2 induce either the same or the reverse order on e.
We present bounds on the minimum number of edges required for these properties and give explicit (non-random) constructions achieving them.
This talk is based on a joint work with Regis Barbosa, Yoshiharu Kohayakawa and Vojtech Rodl.

This presentation explores the connection between cosmic inflation, primordial black holes (PBHs), and Gravitational Waves(GWs). It begins with an overview of inflationary theory and slow-roll parameters, followed by an examination of the role of quantum fluctuations in generating density perturbations that lead to the formation of PBHs. The study also discusses a potential explanation for the gravitational wave observed in PTA data using the Energy-Momentum-Squared Gravity (EMSG) model. The goal is to provide a unified framework that connects inflation, dark matter, and gravitational waves. Finally, a review of multi-field models in the inflationary period will be given, and the results of the K-essence model will be compared with the standard canonical multi-field model.
