Igusa Stacks and the Cohomology of Shimura Varieties II

Patrick Daniels, Pol van Hoften, Dongryul Kim, Mingjia Zhang · 2026

We construct Igusa stacks for all Shimura varieties of abelian type and derive consequences for the cohomology of these Shimura varieties. As an application, we prove that the Fargues--Scholze local L…

Hartree shift and pairing gap in ultracold Fermi gases in the framework of low-momentum interactions

Michael Urban, S. Ramanan · 2026

In this paper we consider a two-component gas of fermions on the BCS side of the BCS-BEC crossover at zero temperature. We use a momentum dependent interaction that reproduces the s-wave scattering ph…

A low-energy effective Hamiltonian for Landau quasiparticles

Pierre-Louis Taillat, Hadrien Kurkjian · 2025

We introduce a new renormalisation scheme to construct the Landau quasiparticles of Fermi fluids. The scheme relies on an energy cutoff $\Lambda$ which removes the quasi-resonant couplings, enabling t…

Undecidability of Linear Logics without Weakening

Jun Suzuki, Katsuhiko Sano · 2025

The goal of this paper is to establish that it remains undecidable whether a sequent is provable in two systems in which a weakening rule for an exponential modality is completely omitted from classic…

Artificial Theory of Mind and Self-Guided Social Organisation

Michael S. Harre, Jaime Ruiz-Serra, Catherine Drysdale · 2024

One of the challenges artificial intelligence (AI) faces is how a collection of agents coordinate their behaviour to achieve goals that are not reachable by any single agent. In a recent article by Oz…

Non-basic rigid packets for discrete $L$-parameters

Peter Dillery, David Schwein · 2024

This article introduces the theory of non-basic rigid inner forms over $p$-adic local fields, extending the basic theory developed by Kaletha. Motivated by the recent work of Bertoloni Meli--Oi on the…

Universal corrections to the superfluid gap in a cold Fermi gas

Silas R. Beane, Zeno Capatti, Roland C. Farrell · 2024

A framework for computing the superfluid gap in an effective field theory (EFT) of fermions interacting via momentum-independent contact forces is developed. The leading universal corrections in the E…

Shrinking targets and recurrent behaviour for forward compositions of inner functions

Anna Miriam Benini, Vasiliki Evdoridou, Nuria Fagella, Philip J. Rippon, Gwyneth M. Stallard · 2024

We prove sharp results about recurrent behaviour of orbits of forward compositions of inner functions, inspired by fundamental results about iterates of inner functions, and give examples to illustrat…

My Boli: Code-mixed Marathi-English Corpora, Pretrained Language Models and Evaluation Benchmarks

Tanmay Chavan, Omkar Gokhale, Aditya Kane, Shantanu Patankar, Raviraj Joshi · 2023

The research on code-mixed data is limited due to the unavailability of dedicated code-mixed datasets and pre-trained language models. In this work, we focus on the low-resource Indian language Marath…

The Gor'kov and Melik-Barkhudarov correction to an imbalanced Fermi gas in the presence of impurities

Heron Caldas, S. Rufo, M. A. R. Griffith · 2022

The effects of induced interactions are calculated in both clean and dirty situations, for balanced and imbalanced Fermi gases. We investigate the effects of nonmagnetic impurities on the induced inte…
