Kavli Affiliate: Todor Milanov | First 5 Authors: Alexander Alexandrov, Todor Milanov, , , | Summary: We construct a Hermitian matrix model for the total descendant potential of a simple singularity of type D similar to the Kontsevich matrix model for the generating function of intersection numbers on the Deligne–Mumford moduli spaces $overline{mathcal{M}}_{g,n}$. | Search […]
Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Bogar Díaz, Juan Margalef-Bentabol, Eduardo J. S. Villaseñor, | Summary: We discuss a simple symplectic formulation for tetrad gravity that leads to the real Ashtekar variables in a direct and transparent way. It also sheds light on the role of the Immirzi […]
Kavli Affiliate: Graham R. Fleming | First 5 Authors: Akihito Ishizaki, Graham R. Fleming, , , | Summary: Giant strides in ultrashort laser pulse technology have enabled real-time observation of dynamical processes in complex molecular systems. Specifically, the discovery of oscillatory transients in the two-dimensional electronic spectra of photosynthetic systems stimulated a number of theoretical […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Kirsti Pajunen, Paolo Celli, Chiara Daraio, , | Summary: In this letter, we provide experimental evidence of bandgap tunability with global prestrain in additively-manufactured tensegrity-inspired lattice structures. These lattices are extremely lightweight and designed to exhibit a nonlinear compressive response that mimics that of a tensegrity structure. […]
Kavli Affiliate: Bo Gu | First 5 Authors: Jing-Yang You, Bo Gu, Gang Su, , | Summary: Honeycomb or triangular lattices were extensively studied and thought to be proper platforms for realizing quantum anomalous Hall effect (QAHE), where magnetism is usually caused by d orbitals of transition metals. Here we propose that square lattice can […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: William C. Waalkes, Zachory K. Berta-Thompson, Karen A. Collins, Adina D. Feinstein, Benjamin M. Tofflemire | Summary: We report the discovery and validation of TOI 122b and TOI 237b, two warm planets transiting inactive M dwarfs observed by textit{TESS}. Our analysis shows TOI 122b has a […]
Kavli Affiliate: Blas Cabrera | First 5 Authors: Belina von Krosigk, Matthew J. Wilson, Chris Stanford, Blas Cabrera, Robert Calkins | Summary: Recent breakthroughs in cryogenic silicon detector technology allow for the observation of single electron-hole pairs released via particle interactions within the target material. This implies sensitivity to energy depositions as low as the […]

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Alejandro Torres-Orjuela, Pau Amaro Seoane, Zeyuan Xuan, Alvin J. K. Chua, María J. B. Rosell | Summary: Gravitational waves from a source moving relative to us can suffer from special-relativistic effects such as aberration. The required velocities for these to be significant are on the order […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Kaley Brauer, Alexander P. Ji, Maria R. Drout, Anna Frebel, | Summary: It is unclear if neutron star mergers can explain the observed r-process abundances of metal-poor stars. Collapsars, defined here as rotating massive stars whose collapse results in a rapidly accreting disk around a black hole […]
