Chiral basis for qubits and spin-helix decay
Vladislav Popkov, Xin Zhang, Frank Göhmann +1
We propose a qubit basis composed of transverse spin helices with kinks. Unlike the usual computational basis, this chiral basis is well suited for describing quantum states with n…
Entanglement spectra of q-deformed higher spin VBS states
Raul A. Santos, Francis N. C. Paraan, Vladimir E. Korepin +1
We calculate the reduced density matrix of a block of integer spin-S's in a q-deformed valence-bond-solid (VBS) state. This matrix is diagonalized exactly for an infinitely long bl…
Entanglement spectra of the q-deformed Affleck-Kennedy-Lieb-Tasaki model and matrix product states
Raul A. Santos, Francis N. C. Paraan, Vladimir E. Korepin +1
We exactly calculate the reduced density matrix of matrix product states (MPS). Our compact result enables one to perform analytic studies of entanglement in MPS. In particular, we…
