Probing the Critical Point (CritPt) of AI Reasoning: a Frontier Physics Research Benchmark
Minhui Zhu, Minyang Tian, Xiaocheng Yang +61
While large language models (LLMs) with reasoning capabilities are progressing rapidly on high-school math competitions and coding, can they reason effectively through complex, ope…
Bilayer construction for mixed state phenomena with strong, weak symmetries and symmetry breakings
Shuangyuan Lu, Penghao Zhu, Yuan-Ming Lu
We introduce the bilayer construction, as a specific purification scheme for a general mixed state, where each mixed state has a one-to-one correspondence with a bilayer pure state…
Obstruction to Broken Symmetries in Topological Flat Bands
Penghao Zhu, Shi Feng, Yuan-Ming Lu
Motivated by the abundance of symmetry breaking states in magic-angle twisted bilayer graphene and other two-dimensional materials, we study superconducting (SC) and charge orders…
New three-dimensional dispersion in the type-II Dirac semimetals PtTe and PdTe revealed through Angle Resolved Photoemission Spectroscopy
Ivan Pelayo, Derek Bergner, Archibald J. Williams +12
PtTe and PdTe are among the first transition metal dichalcogenides that were predicted to host type-II Dirac fermions, exotic particles prohibited in free space. These mate…
