Genuine Global Kochen-Specker Contextuality as Classical Coordination Cost
Ming Yang
We formulate classical simulation of quantum correlations as coordination across a spacetime separator. All past-dependent information capable of influencing the future must cross…
Global Kochen-Specker Contextuality Without Local Contextuality and Generalized Bell Nonlocality
Ming Yang
A set of quantum data can look classical in every local test and still fail to admit a single classical explanation of the whole composite system. We formulate this failure as glob…
Excited states from local effective Hamiltonians of matrix product states and their entanglement spectrum transition
Denise Cocchiarella, Mingru Yang, Yueshui Zhang +3
Solving excited states is a challenging task for interacting systems. For one-dimensional critical systems, however, excited states can be directly accessed from the eigenvectors o…
Ontic Dynamical Locality Reduces to Bell Locality
Ming Yang
Bell inequalities exclude a broad class of local hidden-variable explanations of quantum correlations. A recurring objection is that the usual Bell form is static, whereas real mea…
Extracting conserved operators from a projected entangled pair state
Wen-Tao Xu, Miguel FrÃas Pérez, Mingru Yang
Given a tensor network state, how can we determine conserved operators (including Hamiltonians) for which the state is an eigenstate? We answer this question by presenting a method…
Strings at the Tip of the Cone and Black Hole Entropy From the Worldsheet: Part I
Amr Ahmadain, Ming Yang
We study the nonlinear sigma model (NLSM) worldsheet action describing the motion of closed bosonic strings in the target space of a two-dimensional (2D) flat cone in polar coordin…
