Modular symmetry shapes quintessence and de Sitter vacua
What the study found Modular symmetry in heterotic orbifolds was found to shape a scalar potential with a rich vacuum structure. The authors report anti-de Sitter minima, unstable de Sitter saddle points, and large regions in moduli space supporting multifield hilltop quintessence. Why the authors say this matters The authors conclude that modular symmetry can…
Heterotic supergravity deformations are constructed with vector methods
What the study found The authors constructed bi- and uni-vector deformations of 10d heterotic supergravity solutions. They also generalized the "open/closed" map for this setting and examined examples of the resulting deformed solutions, especially for the F1 string solution. Why the authors say this matters The abstract does not state a broader significance or application…
Localized BFSS phases are linked to instability and phase transitions
What the study found The study finds that the recently discovered localized and non-uniform phases of BFSS matrix quantum mechanics can be derived from first principles. It also finds that the uniform BFSS phase corresponds to a black string in a pp-wave background, which is unstable to a Gregory-Laflamme instability. Why the authors say this…
