Magnetoresistance studies of 2D systems are often shaped by the motion of electrons that occupy spatially confined wave functions, such as topological edge modes and disorder-induced bound states. Directly probing how such states form and b...

We explore the dynamical response of the free surface of an ultrasoft solid driven by a localized moving pressure disturbance. Experiments reveal a steady V-shaped wake analogous to a surface Mach wedge. A simple geometric argument provides...

The Aharonov-Bohm effect is one of the most surprising wonders of the quantum world. Its interpretation is debated between a physical significance of the potential versus nonlocality of quantum physics, ambiguity which cannot be resolved fr...

By leveraging nonlocal airborne acoustic metamaterials, we propose acoustic "ghost tunnels" that enable perfect tunneling while simultaneously functioning as an "empty" space for external waves incident upon their lateral boundaries. This r...

The use of nuclear spins as physical sensing systems is disadvantaged by their low signal responsivity, particularly when compared to sensing techniques based on electron spins. This primarily results from the small nuclear gyromagnetic rat...
Electrically Driven Plasmon-Polaritonic Bistability in Dirac Electron Tunneling Transistors [0.03%]

Bistability-two distinct stable states under identical parameters-is not only a fundamental physical concept but also of importance in practical applications. While plasmon-polaritonic bistability representing history-dependent stable state...

Multiple cosmological observations hint at neutrino self-interactions beyond the standard model, yet such interactions face severe constraints from terrestrial experiments. We resolve this tension by introducing a model where active neutrin...

The dielectric constant of interfacial water is an important parameter, but its measurement has posed challenges, and no consensus has been reached on a generalized expression. We derived a formula for the interfacial dielectric constant of...
