We study the entanglement spectrum (ES) and entropy between two coupled Tomonaga- Luttinger liquids (TLLs) on parallel periodic chains. This problem gives access to the …
We study the momentum space entanglement spectra of bosonic and fermionic formulations of the spin-1/2 XXZ chain with analytical methods and exact diagonalization. We investigate …
We substantiate a complete picture of the “bulk-edge correspondence” conjecture for topological phases. By studying the eigenstates in the entanglement spectrum for both the …
We study momentum-space entanglement in quantum spin-half ladders consisting of two coupled critical XXZ spin-half chains, using field theoretical methods developed by …

We construct and study a two-parameter family of matrix product operators of bond dimension D= 4. The operators M (x, y) act on $({\Bbb {C}} _2)^{\otimes N} $, ie the space of …
In the ground state of gapped systems, the entanglement entropy of a subsystem A scales with the length of the boundary of A. This observation suggests that the entanglement …
1.1 Background Pressure-gain combustion has been studied for several decades, motivated by the potential to improve thermodynamic performance of aerospace and ground-based …
When confined to a finite, two-dimensional area and exposed to a strong magnetic field, electrons exhibit a complicated, highly correlated quantum behavior known as the quantum …
