Cooperative quenching kinetics:Theory and Monte-Carlo simulation

Irina Basieva, Konstantin K. Pukhov, Tasoltan T. Basiev

Analytic expression is given for the static cooperative quenching kinetics in crystals with arbitrary acceptor concentration and arbitrary multipolarity of interaction. For the quenching by two acceptors, the results of Monte-Carlo simulation are also presented which can be approximated in the long-time domain by the nonexponential law I ( t )≅exp[−( wt ) k ], with k =0.41, 0.3, and 0.25 for the multipolarities S =6, 8, and 10, respectively.

Antiferromagnetism and tightly bound Cooper pairs induced by kinetic frustration

Yixin Zhang, Cristian D. Batista, Yang Zhang

Antiferromagnetism and superconductivity are often viewed as competing orders in correlated electron systems. Here, we demonstrate that kinetic frustration in hole motion facilitates their coexistence within the square-lattice repulsive Hubbard model. Combining exact analytical solutions on tailored geometries with large-scale numerical simulations, we reveal a robust pairing mechanism: Holes on opposite sublattices behave as if they carry opposite effective charges due to spin singlet formation from kinetic frustration. This emergent property suppresses phase separation and fosters a coherent [Formula: see text]-wave superconducting channel embedded within a long-range antiferromagnetic background. Our findings establish a minimal yet broadly applicable framework for stabilizing strong-coupling superconductivity in doped Mott insulators.

Cooperative phenomena in yttrium erbium aluminum garnet crystals

V I Zhekov, Vladimir A. Lobachev, T. M. Murina +1 more

An investigation was made of the kinetics of the luminescence due to 4 I 11/2 → 4 I 15/2 and 4 I 13/2 → 4 I 15/2 transitions in the Er 3+ ion in yttrium erbium aluminum garnet crystals subjected to strong resonant excitation argon laser radiation (λ = 4880 nm). The efficiency of the cooperative process resulting in nonlinear quenching of the luminescence from the 4 I 13/2 level and sensitization of the 4 I 11/2 level was estimated. The influence of this process on the kinetics of lasing as a result of the 4 I 11/2 → 4 I 13/2 transition (λ = 2.94 μ) was analyzed.
