The Huang–Yang Formula for the Low‐Density Fermi Gas: Upper Bound

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the ground state energy of a gas of spin 1/2$1/2$ fermions with repulsive short‐range interactions. We derive an upper bound that agrees, at low density ϱ$\varrho$, with the Huang–Yang conjecture. The latter captures the first three terms in an asymptotic low‐density expansion, and in particular the Huang–Yang correction term of order

Self‐Similar Blowup for the Cubic Schrödinger Equation

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

National Identity Meaning and Attitudes Toward War, Peace, and the Future of Ukraine

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT The link between attitudes and social identity is complex, influencing perceptions, motivations, and actions. Social psychological research mainly focused on the role of attitude in identity formation, particularly in the contexts of social movements and collective action.

Resilience Practices and Post‐Traumatic Growth Among Sudanese IDPs

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT In this paper we examine the resilience of internally displaced persons (IDPs) in Sudan who have endured various forms of suffering resulting from being targeted or trapped by militants involved in large‐scale violence. Upon escaping the conflict zones, the civilians exhibit strength, adaptability, and wisdom in the face of various threats to ...
