Quantum Phase Transitions in Transverse Field Spin Models: From Statistical Physics to Quantum Information
TL;DR: The transverse field Ising and XY models (the simplest quantum spin models) provide the organizing principle for the rich variety of interconnected subjects which are covered in this book as mentioned in this paper, including the essentials of quantum dynamics and quantum information.
Journal ArticleDOI
Floquet generation of Majorana end modes and topological invariants
TL;DR: In this paper, it was shown that the number of Majorana end modes can be generated in a one-dimensional system by varying some of the parameters in the Hamiltonian periodically in time.
Journal ArticleDOI
Phase transitions in the quantum Ising and rotor models with a long-range interaction
TL;DR: In this paper, a long-range ferromagnetic interaction between two spins/rotors in units of lattice spacing was considered and the long-term behavior of the interaction drastically modifies the universal critical behaviour of the system.
Journal ArticleDOI
Slow quenches in a quantum Ising chain: Dynamical phase transitions and topology
TL;DR: In this article, the authors studied the slow quenching dynamics of a one-dimensional transverse Ising chain with nearest neighbor ferromagentic interactions across the quantum critical point (QCP) and analyzed the Loschmidt overlap measured using the subsequent temporal evolution of the final wave function with the final time independent Hamiltonian.
Journal ArticleDOI
Mixed state dynamical quantum phase transitions
TL;DR: In this article, the authors considered two versions of the generalized Loschmidt overlap amplitude (GLOA) and showed that the GLOA constructed using the Uhlmann approach does not show any signature of DQPTs at any nonzero initial temperature.
