삼각격자 허버드 시스템에서 스핀 폴라론의 직접 이미징

강상관 물질에서 준입자인 자기 폴라론이 운동 좌절 격자에서도 초교환 상호작용 없이도 관찰될 수 있음을 보여준다.

Directly imaging spin polarons in a kinetically frustrated Hubbard system - Nature

Direct Observation of Itinerant Spin Polarons in a Kinetically Frustrated Hubbard System

Itinerant spin polarons, bound states of a dopant and a spin flip, are directly observed in a triangular-lattice Hubbard system realized with ultracold atoms, revealing enhanced antiferromagnetic correlations around hole dopants and ferromagnetic correlations around charge dopants.

Linear Time-Delay Scheme for Propagating Reduced Electron Density Matrices

The 1RDM Q(t) can be propagated using a linear time-delay scheme based on the Hamiltonian matrix and the B tensor.

Quantum Information Dimension and Geometric Entropy Analysis

The authors explore the concept of geometric quantum states, introducing the quantum information dimension and dimensional geometric entropy to characterize them.
