Thermalization Dynamics in Closed Quantum Many Body Systems: a Precision Large Scale Exact Diagonalization Study
Ivo A. Maceira, Andreas M. Läuchli
Using a Krylov-subspace time evolution algorithm, we simulate the real-time dynamics of translation invariant non-integrable finite spin rings to quite long times with high accurac…
Conformal and chiral phase transitions in Rydberg chains
Ivo A. Maceira, Natalia Chepiga, Frédéric Mila
Using density matrix renormalization group simulations on open chains, we map out the wave-vector in the incommensurate disordered phase of a realistic model of Rydberg chains with…
Perturbative approach to quantum tunneling and quantum interferences in spin clusters
Ivo A. Maceira, Frédéric Mila, Markus Müller
Collective tunneling is a ubiquitous phenomenon in finite-size spin clusters that shows up in systems as diverse as molecular magnets or spin clusters adsorbed at surfaces. The pro…
Infinite coherence time of edge spins in finite-length chains
Ivo Maceira, Frédéric Mila
Motivated by the recent observation that exponentially long coherence times can be achieved for edge spins in models with strong zero modes, we study the impact of level crossings…
Time evolution of localized states in Lieb lattices
J. D. Gouveia, I. A. Maceira, R. G. Dias
We study the slow time evolution of localized states of the open-boundary Lieb lattice when a magnetic flux is applied perpendicularly to the lattice and increased linearly in time…
