DOI: 10.1103/physrevd.99.026002
Abstract: Quantum states with negative energy densities have been long known to exist in quantum field theories. We explore the structure of such states for holographic theories using quantum information theory tools and show how certain… read more here.

DOI: 10.7566/jpsj.91.044005
Abstract: We develop a quantum-inspired numerical procedure for searching low-energy states of a classical Hamiltonian including two-body full-connected random Ising interactions and a random local longitudinal magnetic field. In this method, we introduce infinitesimal quantum interactions… read more here.
