Relative plus constructions
Let h be a connective homology theory. We construct a functorial relative plus construction as a Bousfield localization functor in the category of maps of spaces. It allows us to associate to a pair (X,H), consisting of a connected space X and an hperfect ...
2023Bed for One: A Queer Interpretation of the Rooming House
Understanding the historical and overlapping complexities related to the queer subject, the single bed, and the emergence of the rooming house, helps frame larger theoretical questions about the neglected, yet contradicting by nature, category of queer dom ...
2023Density-wave ordering in a unitary Fermi gas with photon-mediated interactions
Jean-Philippe Brantut, Timo Zwettler, Victor Youri Helson, Kevin Etienne Robert Roux, Hideki Konishi, Elvia Colella
A density wave (DW) is a fundamental type of long-range order in quantum matter tied to self-organization into a crystalline structure. The interplay of DW order with superfluidity can lead to complex scenarios that pose a great challenge to theoretical an ...
NATURE PORTFOLIO2023Data-Driven Discovery of Organic Electronic Materials Enabled by Hybrid Top-Down/Bottom-Up Design
Rubén Laplaza Solanas, Sergio Vela Llausi, Jacob Terence Blaskovits
The high-throughput exploration and screening of molecules for organic electronics involves either a 'top-down' curation and mining of existing repositories, or a 'bottom-up' assembly of user-defined fragments based on known synthetic templates. Both are t ...
Weinheim2023Lie groups in the symmetric group: Reducing Ulam's problem to the simple case
Ulam asked whether all Lie groups can be represented faithfully on a countable set. We establish a reduction of Ulam's problem to the case of simple Lie groups. In particular, we solve the problem for all solvable Lie groups and more generally Lie groups w ...
San Diego2023Continuation Methods For Riemannian Optimization
Daniel Kressner, Axel Elie Joseph Séguin
Numerical continuation in the context of optimization can be used to mitigate convergence issues due to a poor initial guess. In this work, we extend this idea to Riemannian optimization problems, that is, the minimization of a target function on a Riemann ...
SIAM PUBLICATIONS2022The Jordan property for local fundamental groups
Stefano Filipazzi, Roberto Svaldi
We show the Jordan property for regional fundamental groups of klt singularities of fixed dimension. Furthermore, we prove the existence of effective simultaneous index 1 covers for n-dimensional klt singularities. We give an application to the study of lo ...
2022An Equivalence Between Data Poisoning and Byzantine Gradient Attacks
Rachid Guerraoui, Sadegh Farhadkhani, Oscar Jean Olivier Villemaud, Le Nguyen Hoang
To study the resilience of distributed learning, the “Byzantine" literature considers a strong threat model where workers can report arbitrary gradients to the parameter server. Whereas this model helped obtain several fundamental results, it has sometimes ...
PMLR2022Algebra and geometry of link homology Lecture notes from the IHES 2021 Summer School
These notes cover the lectures of the first named author at 2021 IHES Summer School on "Enumerative Geometry, Physics and Representation Theory" with additional details and references. They cover the definition of Khovanov-Rozansky triply graded homology, ...
WILEY2022Protected generation of dissipative Kerr solitons in supermodes of coupled optical microresonators
Tobias Kippenberg, Rui Ning Wang, Mikhail Churaev, Xinru Ji, Aleksandr Tusnin, Kenichi Komagata, Junqiu Liu, Alexey Tikan
A photonic dimer composed of two evanescently coupled high-Q microresonators is a fundamental element of multimode soliton lattices. It has demonstrated a variety of emergent nonlinear phenomena, including supermode soliton generation and soliton hopping. ...
