Boundary quantum critical phenomena with entanglement renormalization
G. Evenbly, R. N. C. Pfeifer, V. Pico +4
We extend the formalism of entanglement renormalization to the study of boundary critical phenomena. The multi-scale entanglement renormalization ansatz (MERA), in its scale invari…
Tensor network decompositions in the presence of a global symmetry
Sukhwinder Singh, Robert N. C. Pfeifer, Guifre Vidal
Tensor network decompositions offer an efficient description of certain many-body states of a lattice system and are the basis of a wealth of numerical simulation algorithms. We di…
Constraining Validity of the Minkowski Energy-Momentum Tensor
R. N. C. Pfeifer, T. A. Nieminen, N. R. Heckenberg +1
There exist two popular energy-momentum tensors for an electromagnetic wave in a dielectric medium. The Abraham expression is robust to experimental verification but more mathemati…
