Information geometry of non-equilibrium quantum states: Mixed metric structures on an extended information manifold
Kouji Kashiwa, Hidefumi Matsuda
We discuss an information-geometric framework for characterizing quantum states in non-equilibrium dynamics. Using the transverse-field Ising chain model as a laboratory, we invest…

Quantum simulation of QC2D on a 2-dimensional small lattice
Zhen-Xuan Yang, Hidefumi Matsuda, Xu-Guang Huang +1
We study the Hamiltonian formulation of SU(2) Yang-Mills theory with staggered fermions in a (2+1)-dimensional small lattice system. We construct a gauge-invariant and finite-dimen…
