Understanding the interplay between egocentric preference and urban structure in shaping human mobility has profound implications for improving epidemic intervention, social equity, and urban resilience. However, numerous existing studies either sole

We reveal an intriguing connection between conformal blocks and fractional calculus. By employing a modified form of half-derivates, we discover a compact representation of the three-dimensional conformal block, expressed as the product of two hyperg

We present a new combinatorial approach to the Ising model incorporating arbitrary bond weights on planar graphs. In contrast to existing methodologies, the exact free energy is expressed as the determinant of a set of ordered and disordered operator

Recently, there has been renewed interest in a crossing-symmetric dispersion relation from the 1970s due to its implications for both regular quantum field theory and conformal field theory. However, this dispersion relation introduces nonlocal spuri

Unraveling the complexities of random packing in three dimensions has long puzzled physicists. While both experiments and simulations consistently show a maximum density of 64 percent for tightly packed random spheres, we still lack an unambiguous an

Quantum criticality typically lies outside the bounds of the conventional Landau paradigm. Despite its significance, there is currently no generic paradigm to replace the Landau theory for quantum phase transition, partly due to the rich variety of q

Science progresses by building upon previous discoveries. It is commonly believed that the impact of scientific papers, as measured by citations, is positively correlated with the impact of past discoveries built upon. However, analyzing over 30 mill

We propose a novel framework for the quantum geometry of expectation values over arbitrary sets of operators and establish a link between this geometry and the eigenstates of Hamiltonian families generated by these operators. We show that the boundar

Many-body wavefunctions usually lie in high-dimensional Hilbert spaces. However, physically relevant states, i.e, the eigenstates of the Schr\"odinger equation are rare. For many-body systems involving only pairwise interactions, these eigenstates fo

Recent empirical studies found different thermodynamic phases for collective motion in animals. However, such a thermodynamic description for human movement remains unclear, mainly due to the limited resolution of existing tracking technologies. In t
