The back-and-forth method for Wasserstein gradient flows
Matt Jacobs, Wonjun Lee, Flavien Léger
We present a method to efficiently compute Wasserstein gradient flows. Our approach is based on a generalization of the back-and-forth method (BFM) introduced by Jacobs and Léger t…
Anisotropic Behavior of Excitons in Single Crystal α-SnS
Van Long Le, Do Duc Cuong, Hoang Tung Nguyen +7
We investigate analytically the anisotropic dielectric properties of single crystal α-SnS near the fundamental absorption edge by considering atomic orbitals. Most striking is the…
Controlling Propagation of epidemics via mean-field control
Wonjun Lee, Siting Liu, Hamidou Tembine +2
The coronavirus disease 2019 (COVID-19) pandemic is changing and impacting lives on a global scale. In this paper, we introduce a mean-field game model in controlling the propagati…
Many-Body Invariants for Chern and Chiral Hinge Insulators
Byungmin Kang, Wonjun Lee, Gil Young Cho
We construct new many-body invariants for 2d Chern and 3d chiral hinge insulators, which are characterized by quantized pumping of dipole and quadrupole moments. The invariants tha…
Generalized Unnormalized Optimal Transport and its fast algorithms
Wonjun Lee, Rongjie Lai, Wuchen Li +1
We introduce fast algorithms for generalized unnormalized optimal transport. To handle densities with different total mass, we consider a dynamic model, which mixes the optim…
