Chiral Pseudogap Metal Emerging from a Disordered Van der Waals Mott Insulator 1T‐TaS2 − xSex
An intriguing metal was discovered in a chiral charge density wave material, 1T‐TaS2. The random substitution of S by Se induces a transition from an insulator to a metal with a strongly suppressed electron density at the Fermi energy. The pseudogap comes from electronic disorder on with substantial electron correlation and exhibits unprecedented ...

Elliptic systems at resonance for jumping non-linearities
In this article, we study the existence of nontrivial solutions for the problem $$\displaylines{ -\Delta u=\alpha _1u^{+}-\beta _1u^{-}+f(x,u,v)+h_1( x) \quad \text{in }\Omega, \cr -\Delta v=\alpha _2v^{+}-\beta _2v^{-}+g(x,u,v)+h_2( x) \quad \text ...

Manipulating the Assembly and Architecture of Fibrillar Silk
In this study, advanced in situ AFM, PiFM, and Cryo‐EM are leveraged to realize in situ observations of nucleation, growth, and degradation of silk nanofibrils. A clear picture of the assembly and structural evolution of regenerated silk nanofibrils is defined and demonstrates a novel strategy for manipulating their structure and properties, which ...

A note on nonlinear elliptic systems involving measures
We study the existence and regularity of solutions to nonlinear elliptic systems whose right-hand side is a measure-valued function. Using a sign condition instead of structure conditions, we obtain the same as those presented by Dolzmann, Hungerbuhler ...

A novel approach is introduced that leverages polymer phase transitions to modulate brush behavior. The oleophilic bottle brush system exhibits two distinct melting transitions—bulk and surface—enabling a two‐stage swelling and wetting transition.

Optimal boundary control for a time dependent thermistor problem
An optimal control of a two dimensional time dependent thermistor problem is considered. The problem consists of two nonlinear partial differential equations coupled with appropriate boundary conditions which model the coupling of the thermistor to ...

Proposing Altermagnetic‐Ferroelectric Type‐III Multiferroics with Robust Magnetoelectric Coupling
Multiferroics are highly sought after for advanced technological applications. Here, a novel class of type‐III multiferroics is proposed, where ferroelectricity and altermagnetism are inherently interlocked by crystal symmetry, setting them apart from conventional multiferroics. The ferroelectric switching is shown to fully invert the spin polarization
