The Maximum Number of Shortest Paths in Graphs
Jing Yu, Jie-Xiang Zhu
Benjamini and Tzalik obtained an upper bound on the number of shortest paths between two vertices at distance in a multigraph of maximum degree at most , and proposed a conj…

MOSI. AI, :, Donghua Yu +23
Speaker-Attributed, Time-Stamped Transcription (SATS) aims to transcribe what is said and to precisely determine the timing of each speaker, which is particularly valuable for meet…
Photon Blockade Mediated by Two-Photon Absorption in an Optical Parametric Amplifier
Weiyi An, Jie Zhu
Photon blockade (PB) is a quantum effect in strongly nonlinear systems where a single photon prevents the system from being excited to a higher level, generating anti-bunched light…
Non-Hermitian quantum geometric tensor and nonlinear electrical response
Kai Chen, Jie Zhu
We demonstrate that the non-Hermitian quantum geometric tensor (QGT) governs nonlinear electrical responses in systems with a spectral line gap. The quantum metric, which is the sy…
Counting degree-constrained orientations
Jing Yu, Jie-Xiang Zhu
We study the enumeration of graph orientations under local degree constraints. Given a finite graph and a family of admissible sets $\{\mathsf P_v \subseteq \mathbb{Z}…
