Frustration, Area Law, and Interference in Quantum Spin Models
Aditi Sen De, Ujjwal Sen, Jacek Dziarmaga +2
We study frustrated quantum systems from a quantum information perspective. Within this approach, we find that highly frustrated systems do not follow any general ''area law'' of b…
Quantum phase transition in the one-dimensional compass model
Wojciech Brzezicki, Jacek Dziarmaga, Andrzej M. Oles
We introduce a one-dimensional model which interpolates between the Ising model and the quantum compass model with frustrated pseudospin interactions and $σ_i^xσ_{…
Entropy of entanglement and correlations induced by a quench: Dynamics of a quantum phase transition in the quantum Ising model
Lukasz Cincio, Jacek Dziarmaga, Marek M. Rams +1
Quantum Ising model in one dimension is an exactly solvable example of a quantum phase transition. We investigate its behavior during a quench from a paramagnetic to ferromagnetic…
