Summary: The quest for a minimally representational behavior has been a long-standing issue, and through neurophysiologically-informed behavioral studies, a basic form of representation has been found in the visually-guided obstacle avoidance behavior of the cubozoan medusa. This form of structural representation distinguishes itself substantially from mere sensory indicators, and the minimal nature of this case is defended and qualitatively demarcated against objections from liberal representationalists. Finally, the implications of this thesis within a naturalistic framework are briefly discussed.

Summary: By heuristically deriving the Hawking temperature and Bekenstein entropy from the existence of a minimal resolvable area, we found quantum gravity corrections that are qualitatively consistent with results obtained by other methods. The size of the minimal area is constrained by semiclassical black hole physics, particularly by the entropy content of Hawking radiation. The derivation method is also applied to finding the Unruh temperature associated with causal diamonds and establishing a new relation between this temperature and the entropy of the causal diamond's horizon.

Summary: In this work, the near horizon and asymptotic symmetries of static and rotating hairy-AdS black holes were investigated within the framework of general minimal massive gravity. The energy, angular momentum, and entropy of the solutions were obtained and shown to be consistent with the first law of black hole thermodynamics. Additionally, near horizon conserved charges and their algebra were found by considering the near horizon geometry of the black hole, with conserved charges expressed in terms of zero modes through Fourier modes.

Summary: Shortcuts to isothermality are a strategy for driving a system to its equilibrium states and evaluating the impact of control. Finding the optimal scheme to minimize energy cost is crucial, and it has been proven to be equivalent to finding the geodesic path in the space of control parameters. This equivalence provides a systematic and universal approach to finding optimal control for reducing energy cost.

Summary: Assuming the existence of an effective charge to define the evolution scheme for parton distribution functions (DFs), this study derives strict lower and upper bounds on all Mellin moments of the valence-quark DFs of pionlike systems. By using numerical simulations of lattice-regularized quantum chromodynamics (QCD) consistent with these bounds, parameter-free predictions for pion valence, glue, and sea DFs are obtained. The study shows that the form of the valence-quark DF is consistent with predictions derived from the QCD-prescribed behavior of the pion wave function.

Summary: In this study, we investigate the possibilities of integration on the minimal Z(2)(2)-superspace. Two definitions are taken from previous works and their generalizations are examined. It is found that these definitions impose restrictions on the integrable functions. To solve this issue, a new definition of integral is introduced, inspired by previous work, which does not impose restrictions on the integrable functions. An interesting feature of this new definition is the emergence of a spatial coordinate, allowing the integral to be defined on R-2 despite the (0,0) part of the minimal Z(2)(2)-superspace being R.

Summary: Landauer's principle imposes a fundamental limit on the energy cost of perfectly initializing a classical bit, but in practical operations, the finite operation time leads to an increase in energy cost. Specifically, when initializing the bit, the smaller the error, the higher the energy cost. A finite-time isothermal process can be used for bit initialization, and an optimal protocol to minimize the energy cost is proposed.

Summary: In this paper, a mean field game model inspired by crowd motion is investigated. The model involves interacting populations striving to reach given target sets in minimal time. Each agent's movement is described by a control system that depends on their position, the distribution of other agents in the same population, and the distribution of agents in other populations. The paper explores the existence of Lagrangian equilibria, their asymptotic behavior, and their characterization as solutions of a mean field game system, with few regularity assumptions on agents' dynamics.

Summary: Asymptotic safety is an example of how ideas from statistical physics can be applied to high-energy physics. It is connected to fixed points of the renormalization-group flow and extends the concept of asymptotic freedom to a scale-invariant UV completion with non-vanishing interactions. This review discusses the key ideas behind asymptotic safety, the mechanism for achieving it, and its implications for gauge-Yukawa field theories. It also explores potential applications and provides an overview of standard model extensions that may exhibit asymptotic safety.

Summary: The aim of this paper is to analyze the asymptotic behavior of the minimal random walk (MRW) using a new martingale approach. The MRW has three regimes depending on its parameters, and this paper provides new results on the asymptotic behavior of MRW in the diffusive, critical, and superdiffusive regimes. The study proves the convergence of MRW to a nondegenerate random variable and shows that the fluctuation of MRW is still Gaussian. The paper also presents results on the center of mass of MRW.

Summary: The effect of minimal length on quantum heat engine systems is investigated using a system of trapped Fermi particles in an infinite potential well. The reversible Lenoir cycle is chosen as the thermodynamic cycle. Both single particle and multiparticle cases are considered. The results show that the minimal length enhances the efficiency of the engine when the width of the potential well tends to zero.

Summary: The critical behavior of shift symmetric interacting theories with higher derivative kinetic terms is studied. Single scalar theories with shift symmetry are classified and analyzed, and their beta functions, criticality conditions, and universal anomalous dimensions are computed. It is shown that these theories are conformally invariant at the fixed point of the RG flow.

Summary: This paper discusses the energy momentum tensors of higher-derivative free scalar conformal field theories and spinor theories, and describes two algorithms for their computation. The paper also presents new compact expressions for the energy momentum tensors and highlights specific obstructions to defining them as conformal primary operators in some spacetime dimensions.

Summary: In type IIB fibre inflation models, it has been argued that the instability caused by tachyonic isocurvature perturbations is unphysical due to the use of ill-defined entropy variables. By employing the correct relative entropy perturbation, it has been demonstrated that axionic isocurvature perturbations decay during inflation and the dynamics becomes essentially single-field.

Summary: We discuss the usefulness and theoretical consistency of different entropy variables used in the literature to describe isocurvature perturbations in multifield inflationary models. We clarify which is the proper entropy variable to be used to compare with observational constraints. We find that commonly used variables can lead to wrong results or unphysical destabilisation effects for cases with light kinetically coupled spectator fields.
