The strongly correlated interactions found in twisted bilayer systems give rise to a range of exotic phenomena but due to range of factors it is challenging to develop theoretical models that can faithfully describe the underlying physics. Here, the authors provide an analysis of the chiral limits of perturbed Dirac field theories that are relevant to C3-symmetric twisted bilayer graphene and transition metal dichalcogenides homobilayers. They identify two possible scenarios and show that flat bands are a more likely phenomenon in the latter system

Understanding the hybridization due to orbital overlap in solids allows justification for adjusting electron correlation and hopping integral under the Hubbard model. This work links spatial-overlap-driven to energetic-overlap-driven hybridization from perovskite oxides by resonant inelastic X-ray scattering at La N_4,5 edges.

Condensates with a shell can be formed by liquid-liquid phase separation and can burst like viscous bubbles by nucleation and growth of a hole in the shell surrounded by a rim. The authors develop a model to extract a broad range of rheological properties for spherical shells to understand the conditions for bursting.

When a pulsed laser interacts with tissue, the molecules in the sample get excited to a higher energy state and relax either nonradiatively, leading to thermal damage, or via de-excitation processes, frequently associated with photodamage. Here, the authors explore how different photodamage mechanisms unfold across a spectrum of intense near-infrared femtosecond pulses.

When implemented on quantum computers, lattice gauge theory should be able to address significant new scientific questions about quarks and gluons. The authors of this paper replace the traditional Cartesian lattice by one that has unique symmetry properties, and they use this new lattice to perform an error-mitigated quantum computer calculation.

By using the sweeping cluster quantum Monte Carlo algorithm, the authors reveal the complete ground-state phase diagram of the triangular-lattice fully packed quantum loop model. They discover a hidden vison plaquette phase between the known lattice nematic solid and the even \({{\mathbb{Z}}}_{2}\) quantum spin liquid (QSL) phase, which had been previously misinterpreted as the QSL, and explain how to detect it experimentally.

Large structure in the Universe, such as galaxies, are believed to form by a process called violent relaxation, which occurs over millions of years. The authors present a nonlinear optics experiment which shows direct observation of violent relaxation, whose evolution can be related to the equations governing galaxy formation.

Topological quantum states are essential resources in quantum error correction and quantum simulation but unitary quantum circuits for their preparation require extensive circuit depth. The authors demonstrate a constant-depth protocol to prepare topologically ordered states on a trapped-ion quantum computer using non-unitary operations.

This paper presents a study on topologically enhanced third harmonic generation within resonant nonlinear topolectrical circuits. The authors demonstrate that the implementation of a mirror-stacking approach in one-dimensional topological circuits enables achieving significant harmonic wave power increase, leading to efficient nonlinear processes.

The study of the general factors underlying clogging are fragmented and application-driven due to its broad spectrum of applications. The authors propose a holistic understanding of the clogging process by investigating the clogging of a granular hopper flow using high-speed imaging, finding a signature formation of precursory chain structures.

Recent theoretical works have predicted lasing/condensation in multimode exciton-polaritons, hybrid light-matter quasiparticles, but the origin and the dynamics of multimode condensation has not been experimentally investigated. The authors study the dynamics of multimode exciton-polariton condensation, revealing the experimental signatures of mode competition.

This research explores how incident angles affect topological phase transitions in one-dimensional photonic crystals, impacting both TE and TM polarized modes. By precisely tuning the incident angle, the study reveals the ability to split TE-TM polarized topological interface states, paving the way for innovations in optical communications and integrated photonic devices.

The trajectory of the active droplets in an isotropic environment can be controlled by gradients of chemicals, physical obstacles, or by electric fields, but these methods are either static, transient, or require a complicated design. The authors demonstrate a simple optical method to control the trajectories of active droplets remotely by placing them in a photosensitive cholesteric liquid crystal environment.
