The 2nd Workshop on Muon Science Technology and Industry is scheduled to be held at the China Spallation Neutron Source (CSNS) from January 10 to 12, 2025. This workshop will focus on muSR applications, negative muon applications, and other relevant topics related to the muon station of CSNS Phase-II Project (CSNS-II), named MELODY (Muon station for sciEnce, technoLOgy, and inDustrY). The construction of CSNS-II officially started in January 2024, and the project is expected to be completed and pass national evaluation by October 2029. 

This workshop is organized by the Spallation Neutron Source Science Center and the Institute of High Energy Physics, Chinese Academy of Sciences.

16:05 µSR Signatures of Pseudogap and Critical Spin Dynamics in the Kondo Condensate of P-Doped Silicon

Doped silicon offers a rich platform for exploring quantum many-body phenomena arising from the interplay of spatial inhomogeneity, magnetism, and electron correlations. At intermediate densities of magnetic impurities, phosphorus-doped silicon (Si:P) hosts a Kondo condensate, characterized by an energy gap in the electronic density of states. In this regime, randomly distributed Kondo clouds overlap and interact via Ruderman–Kittel–Kasuya–Yoshida (RKKY) interactions, yet the precise nature of its magnetic ground state remains unresolved. In this talk, I will present our study of the magnetic ground state and spin dynamics of Si:P using electron and muon spin resonance (ESR and μSR). The ESR data reveal a gradual crossover from the Korringa regime to the spin-fluctuation regime between 22 K and 150 K, with the development of Kondo-singlet fluctuations below 22 K, eventually leading to the formation of Kondo singlets below 6 K. Complementary μSR results indicate that Kondo singlets with a singlet gap $\Delta_{\mathrm{ZF}}$ = 0.8(4) K emerge below $T_{\mathrm{K}}$ = 2.4 K, followed by the formation of a correlated Kondo state at $T^{*}$ = 0.6 K, characterized by a power-law dependence, $-K_{\mu}T \sim T^{\xi}$. This Kondo condensate state exhibits a coexistence of a Bardeen-Cooper-Schrieffer-like charge gap and critical magnetic fluctuations, drawing striking parallels to the pseudogap phases observed in doped Mott insulators. These findings extend the scope of pseudogap phenomena, highlighting their relevance in the domain of doped semiconductors.
