Universal Quantum Birthmark: Ghost of the quantum past
Ivy Xiaoya, Anton M. Graf, Eric J. Heller +1
Quantum dynamics retains a permanent and universal memory of its initial conditions, even in systems whose spectra display fully chaotic, random-matrix behavior. This effect, known…
Adiabaticity Crossover: From Anderson Localization to Planckian Diffusion
Tiange Xiang, Yubo Zhang, Joonas Keski-Rahkonen +2
We investigate electron transport in one dimension from the quantum-acoustic perspective, where the coherent-state representation of lattice vibrations results in a time-dependent…
Quantum Acoustics Demystifies the Strange Metals
Eric J. Heller, Alhun Aydin, Anton M. Graf +11
Phonons have long been thought to be incapable of explaining key phenomena in strange metals, including linear-in-\textit{T} Planckian resistivity from high to very low temperature…
HARDMath2: A Benchmark for Applied Mathematics Built by Students as Part of a Graduate Class
James V. Roggeveen, Erik Y. Wang, Will Flintoft +42
Large language models (LLMs) have shown remarkable progress in mathematical problem-solving, but evaluation has largely focused on problems that have exact analytical solutions or…
