20.500.12556/RUL-181716 Doublon-holon pairing state in photodoped Mott insulators We demonstrate the existence of an unconventional pairing state in photodoped Mott insulators on ladder and quasi-two-dimensional geometries, characterized by quasi-long-range doublon-holon correlations that signal Mott exciton condensation. The doublon-holon pairing exhibits correlations of d-wave-like symmetry, reminiscent of superconducting pairing in chemically doped Mott insulators. By constructing the phase diagram, using density matrix renormalization group, we reveal that the doublon-holon pairing state in the photodoped ladder emerges between the spin-singlet, charge-density-wave, and $\eta$-pairing phases. Our study suggests that the interplay of charge, spin, and $\eta$-spin degrees of freedom can give rise to exotic quantum many-body states in photodoped Mott insulators. condensed matter physics pairing mechanisms photoinduced effect Mott insulators quantum many-body systems strongly correlated systems density matrix renormalization group Hubbard model fizika kondenzirane snovi fotoinducirani pojavi Mottovi izolatorji kvantni večdelčni sistemi močno korelirani sistemi renormalizacijska grupa gostotne matrike Hubbardov model true false true Angleški jezik Slovenski jezik Članek v reviji 2026-04-14 11:55:00 2026-04-14 11:55:02 2026-04-15 04:25:17 0000-00-00 00:00:00 2026 0 0 Str.
