Measurements of the quantum geometric tensor in solids
Mingu Kang, Sunje Kim, Yuting Qian +15
Understanding the geometric properties of quantum states and their implications in fundamental physical phenomena is at the core of modern physics. The Quantum Geometric Tensor (QG…
Kernel Methods for the Approximation of the Eigenfunctions of the Koopman Operator
Jonghyeon Lee, Boumediene Hamzi, Boya Hou +3
The Koopman operator provides a linear framework to study nonlinear dynamical systems. Its spectra offer valuable insights into system dynamics, but the operator can exhibit both d…
Bilayer orthogonal ferromagnetism in CrTe-based van der Waals system
Chiara Bigi, Cyriack Jego, Vincent Polewczyk +19
Systems with pronounced spin anisotropy play a pivotal role in advancing magnetization switching and spin-wave generation mechanisms, which are fundamental for spintronic technolog…
Market allocations under conflation of goods
Niccolò Urbinat, Marco LiCalzi
We study competitive equilibria in exchange economies when a continuum of goods is conflated into a finite set of commodities. The design of conflation choices affects the allocati…
Comment on 'Sparse Bayesian Factor Analysis when the Number of Factors is Unknown' by S. Frühwirth-Schnatter, D. Hosszejni, and H. Freitas Lopes
Roberto Casarin, Antonio Peruzzi
The techniques suggested in Frühwirth-Schnatter et al. (2024) concern sparsity and factor selection and have enormous potential beyond standard factor analysis applications. We sho…
Flexible space-time models for extreme data
Lorenzo Dell'Oro, Carlo Gaetan
Extreme value analysis is an essential methodology in the study of rare and extreme events, which hold significant interest in various fields, particularly in the context of enviro…
Pomeranchuk instability from electronic correlations in CsTiBi kagome metal
Chiara Bigi, Matteo Dürrnagel, Lennart Klebl +19
Among many-body instabilities in correlated quantum systems, electronic nematicity, defined by the spontaneous breaking of rotational symmetry, has emerged as a critical phenomenon…
Nash Meets Wertheimer: Using Good Continuation in Jigsaw Puzzles
Marina Khoroshiltseva, Luca Palmieri, Sinem Aslan +2
Jigsaw puzzle solving is a challenging task for computer vision since it requires high-level spatial and semantic reasoning. To solve the problem, existing approaches invariably us…
Terahertz-driven parametric excitation of Raman-active phonons in LaAlO
M. Basini, V. Unikandanunni, F. Gabriele +7
Achieving parametric excitation in an oscillating physical system involves periodically adjusting one of its parameters to modulate the oscillator's natural frequency. This phenome…
Early Exit Strategies for Approximate k-NN Search in Dense Retrieval
Francesco Busolin, Claudio Lucchese, Franco Maria Nardini +3
Learned dense representations are a popular family of techniques for encoding queries and documents using high-dimensional embeddings, which enable retrieval by performing approxim…
Theory of polymers in binary solvent solutions: mean-field free energy and phase behavior
Davide Marcato, Achille Giacometti, Amos Maritan +1
We present a lattice model for polymer solutions, explicitly incorporating interactions with a bath of solvent and cosolvent molecules. By exploiting the well-known analogy between…
Laplacian Renormalization Group: An introduction to heterogeneous coarse-graining
Guido Caldarelli, Andrea Gabrielli, Tommaso Gili +1
The renormalization group (RG) constitutes a fundamental framework in modern theoretical physics. It allows the study of many systems showing states with large-scale correlations a…
The interplay between liquid-liquid and ferroelectric phase transitions in supercooled water
Maria Grazia Izzo, John Russo, Giorgio Pastore
The distinctive characteristics of water, evident in its thermodynamic anomalies, have implications across disciplines from biology to geophysics. Considered a valid hypothesis to…
Phase behaviour and self-assembly of semiflexible polymers in poor-solvent solutions
Tobia Arcangeli, Tatjana Škrbić, Somiealo Azote +6
Using Langevin dynamics complemented by Wang-Landau Monte Carlo simulations, we study the phase behavior of single and multiple semiflexible polymer chains in solution under poor-s…
Leveraging Content Producer Networks and User Perception to Detect Online Discursive Communities
Stefano Guarino, Ayoub Mounim, Guido Caldarelli +1
Online discussions are often characterized by strong behavioral asymmetries: a relatively small fraction of users actively produces content, while the majority primarily consumes a…
Spin-dependent gap in graphene on a magnetic substrate
P. M. Sheverdyaeva, G. Bihlmayer, E. Cappelluti +12
We present a detailed analysis of the electronic properties of graphene/Eu/Ni(111). By using angle and spin-resolved photoemission spectroscopy and ab initio calculations, we show…
Algorithms for Galois Words: Detection, Factorization, and Rotation
Diptarama Hendrian, Dominik Köppl, Ryo Yoshinaka +1
Lyndon words are extensively studied in combinatorics on words -- they play a crucial role on upper bounding the number of runs a word can have [Bannai+, SIAM J. Comput.'17]. We ca…
A Learning-to-Rank Formulation of Clustering-Based Approximate Nearest Neighbor Search
Thomas Vecchiato, Claudio Lucchese, Franco Maria Nardini +1
A critical piece of the modern information retrieval puzzle is approximate nearest neighbor search. Its objective is to return a set of data points that are closest to a query…
Intergenerational Insurance
Francesco Lancia, Alessia Russo, Tim Worrall
How should successive generations insure each other when the young can default on previously promised transfers to the old? This paper studies intergenerational insurance that maxi…
Smart Contract Languages: a comparative analysis
Massimo Bartoletti, Lorenzo Benetollo, Michele Bugliesi +11
Smart contracts have played a pivotal role in the evolution of blockchains and Decentralized Applications (DApps). As DApps continue to gain widespread adoption, multiple smart con…
