A Unified Description of Electron-Phonon Coupling and Ion Migration in Metal Halide Perovskites
Bo Cai, Yan Yang, Yoshiki Sugai +11
The remarkable optoelectronic properties of metal halide perovskites are closely linked to their unusually soft and polar chemical bonds that enable both strong electron-phonon int…

Functional methods for quantum thermodynamics
Sibo Wang, Samuel Degen, Haozhao Liang
The functional renormalization group provides a nonperturbative and systematically improvable route to constructing density functionals for quantum many-body systems from microscop…

Speed of sound bounds and first-order phase transitions in compact stars
P. Laskos-Patkos, G. A. Lalazissis, Sibo Wang +3
In the present study, we employ three distinct, physically motivated speed of sound bounds to construct hybrid models, where the high-density phase is described by the maximally st…
