Co-phthalocyanine (CoPc) is a prototypical molecular magnet with a spin of 1/2, which has been shown to be too fragile when the molecule is adsorbed on good metals but can be preserved on the semimetallic Sb(111) substrate. Here, we use first-principles calculations to reveal that, counterintuitively, the spin of individual CoPc is also quenched on the semimetallic Bi(111) substrate, and the underlying reason is attributed to a significant elevation of the Fermi level close to the Co-<mjx-container ctxtmenu_counter=\"24\" ctxtmenu_oldtabindex=\"1\" jax=\"CHTML\" overflow=\"linebreak\" role=\"tree\" sre-explorer- style=\"font-size: 100.7%;\" tabindex=\"0\"><mjx-math data-semantic-structure=\"(4 0 (3 1 2))\"><mjx-msub data-semantic-children=\"0,3\" data-semantic- data-semantic-owns=\"0 3\" data-semantic-role=\"latinletter\" data-semantic-speech=\"d Subscript z squared\" data-semantic-type=\"subscript\"><mjx-mi data-semantic-annotation=\"clearspeak:simple\" data-semantic-font=\"italic\" data-semantic- data-semantic-parent=\"4\" data-semantic-role=\"latinletter\" data-semantic-type=\"identifier\"><mjx-c>𝑑</mjx-c></mjx-mi><mjx-script style=\"vertical-align: -0.15em;\"><mjx-msup data-semantic-children=\"1,2\" data-semantic- data-semantic-owns=\"1 2\" data-semantic-parent=\"4\" data-semantic-role=\"latinletter\" data-semantic-type=\"superscript\" size=\"s\"><mjx-mrow><mjx-mi data-semantic-annotation=\"clearspeak:simple\" data-semantic-font=\"italic\" data-semantic- data-semantic-parent=\"3\" data-semantic-role=\"latinletter\" data-semantic-type=\"identifier\"><mjx-c>𝑧</mjx-c></mjx-mi></mjx-mrow><mjx-script style=\"vertical-align: 0.289em;\"><mjx-mn data-semantic-annotation=\"clearspeak:simple\" data-semantic-font=\"normal\" data-semantic- data-semantic-parent=\"3\" data-semantic-role=\"integer\" data-semantic-type=\"number\" size=\"s\"><mjx-c>2</mjx-c></mjx-mn></mjx-script></mjx-msup></mjx-script></mjx-msub></mjx-math></mjx-container> orbital by the stronger spin-orbit coupling in bismuth.

Despite the exponentially large configuration space, we show that the generic correlation of distances between configurations, with a degree of freedom proportional to the lattice size, can probe phase transitions using importance sampling procedures like Monte Carlo simulations. The distribution of sampled distances varies significantly across different phases, suggesting universal critical behavior for uncertainty and participation entropy. For various classical spin models with different phases and transitions, finite-size analysis based on these quantities accurately identifies phase transitions and critical points. Notably, in all cases, the critical exponent derived from the uncertainty of distances equals the anomalous dimension governing real-space correlation decay. Thus, configuration space correlations, defined by distance uncertainties, share the same decay ratio as real-space correlations, determining the universality class of phase transitions.

By means of first-principles density functional theory calculations, we predict the evolution of the surface states, analyzing their dispersion and spin texture, eventually showing a relevant modulation of their filling as a function of the uniaxial in-plane strain conditions.
