Curvature Converts Phonon Hall Viscosity into Phonon Angular Momentum
Pablo A. Morales
In a flat crystalline membrane, the low-energy spectrum is dominated by a flexural mode that does not couple to phonon Hall viscosity. We show that static curvature converts normal…
Curvature-Controlled Infrared Regularization of Crystalline Membranes
Pablo A. Morales, Pavel Castro-Villarreal
We show that negative Gaussian curvature regularizes the infrared sector of crystalline membranes. In a covariant formulation of embedded elasticity, the Green strain contains a sy…
An Information-Geometric Approach to Artificial Curiosity
Alexander Nedergaard, Pablo A. Morales
Learning in environments with sparse rewards remains a fundamental challenge in reinforcement learning. Artificial curiosity addresses this limitation through intrinsic rewards to…
Explosive neural networks via higher-order interactions in curved statistical manifolds
Miguel Aguilera, Pablo A. Morales, Fernando E. Rosas +1
Higher-order interactions underlie complex phenomena in systems such as biological and artificial neural networks, but their study is challenging due to the scarcity of tractable m…
Graphene shapes from quantum elasticity
Pablo A. Morales, Pavel Castro-Villarreal
Temperature constraints are highly desirable in the experimental setup when seeking the synthesis of new carbon structures. Fluctuations of the Dirac field result in temperature-de…
Thermodynamics of exponential Kolmogorov-Nagumo averages
Pablo A. Morales, Jan Korbel, Fernando E. Rosas
This paper investigates generalized thermodynamic relationships in physical systems where relevant macroscopic variables are determined by the exponential Kolmogorov-Nagumo average…
Emergent spacetime from a Berry-inspired dynamical gauge field coupled to electromagnetism
Patrick Copinger, Pablo Morales
Motivated by the fermionic Berry's phase in momentum space, we study a local Abelian phase in momentum space coupled to electromagnetism, for complex scalars in the phase-space wor…
Curvature-induced pseudogauge fields from time-dependent geometries in graphene
Pablo A. Morales, Patrick Copinger
The massless Dirac equation is studied in curved spacetime on the (2+1)-dimensional graphene sheet in time-dependent geometries. Emergent pseudogauge fields are found both in the a…
Geometric Structures Induced by Deformations of the Legendre Transform
Pablo A. Morales, Jan Korbel, Fernando E. Rosas
The recent link discovered between generalized Legendre transforms and non-dually flat statistical manifolds suggests a fundamental reason behind the ubiquity of Rényi's divergence…
A generalization of the maximum entropy principle for curved statistical manifolds
Pablo A. Morales, Fernando E. Rosas
The maximum entropy principle (MEP) is one of the most prominent methods to investigate and model complex systems. Despite its popularity, the standard form of the MEP can only gen…
Schwinger Pair Production in SL Topologically Non-Trivial Fields via Non-Abelian Worldline Instantons
Patrick Copinger, Pablo Morales
Schwinger pair production is analyzed in a BPST instanton background and in its SL complex extension for complex scalar particles. A non-Abelian extension of the wo…
Field Theory of the Eulerian Perfect Fluid
Taketo Ariki, Pablo A. Morales
The Eulerian perfect-fluid theory is reformulated from its action principle in a pure field-theoretic manner. Conservation of the convective current is no longer imposed by Lin's c…
Spatial modulation and topological current in holographic QCD matter
Kenji Fukushima, Pablo Morales
We investigate an impact of the axial-vector interaction on spatial modulation of quark matter. A magnetic field coupled with baryon density leads to a topological axial current, s…
Thermal nonlocal Nambu--Jona-Lasinio model in the real time formalism
M. Loewe, P. Morales, C. Villavicencio
The real-time formalism at finite temperature and chemical potential for the nonlocal Nambu--Jona-Lasinio model is developed in the presence of a Gaussian covariant regulator. We c…
