Problems in Number Theory related to Mathematical Physics

open access: yes, 2008
This thesis consists of an introduction and four papers. All four papers are devoted to problems in Number Theory. In Paper I, a special class of local ζ-functions is studied. The main theorem states that the functions have all zeros on the line Re(s)=1/2.This is a natural generalization of the result of Bump and Ng stating that the zeros of the Mellin

Independent Wavefront Multiplexing with Metasurfaces via Non‐Injective Transformation

open access: yesAdvanced Materials, EarlyView.
In this work, a universal metasurface multiplexing strategy is presented based on non‐injective transformation. By jointly optimizing two metasurfaces, multiplexed channels achieve independent wavefront control, overcoming crosstalk limits of single‐layer designs.

From Molecules to Modules: Advanced Characterization of Membrane Systems

open access: yesAdvanced Materials, EarlyView.
Membrane technologies can enhance the efficiency and selectivity of chemical separations in energy‐water systems. Improving our understanding and design of separation membranes will require studying their properties at the molecular scale, mesoscale, and macroscale. This perspective highlights advanced characterization techniques for revealing membrane

Revealing the Neglected Role of Passivation Layers of Current Collectors for Solid‐State Anode‐Free Batteries

open access: yesAdvanced Materials, EarlyView.
An in situ X‐ray absorption spectroscopy experiment revealed that the surface passivation layers on copper and stainless steel interact with the sulfide‐based solid‐state electrolyte upon contact, leading to the formation of various interfacial species.
