Topological crystals and soliton lattices in a Gross-Neveu model with Hilbert-space fragmentation
Sergio Cerezo-Roquebrún, Simon Hands, Alejandro Bermudez
We explore the finite-density phase diagram of the single-flavour Gross-Neveu-Wilson (GNW) model using matrix product state (MPS) simulations. At zero temperature and along the sym…
The Interspersed Spin Boson Lattice Model
A. Kurcz, J. J. Garcia-Ripoll, A. Bermudez
We describe a family of lattice models that support a new class of quantum magnetism characterized by correlated spin and bosonic ordering [Phys. Rev. Lett. 112, 180405 (2014)]. We…
Noise Studies of Driven Geometric Phase Gates with Trapped Ions
A. Lemmer, A. Bermudez, M. B. Plenio
We present a study of the performance of the trapped-ion driven geometric phase gates introduced in [New J. Phys. 15, 083001 (2013)] when realized in a stimulated Raman transition.…
Lieb-Robinson bounds for spin-boson lattice models and trapped ions
J. Juenemann, A. Cadarso, D. Perez-Garcia +2
We derive a Lieb-Robinson bound for the propagation of spin correlations in a model of spins interacting through a bosonic lattice field, which satisfies itself a Lieb-Robinson bou…
Controlling and measuring quantum transport of heat in trapped-ion crystals
A. Bermudez, M. Bruderer, M. B. Plenio
Measuring heat flow through nanoscale systems poses formidable practical difficulties as there is no `ampere meter' for heat. We propose to overcome this problem by realizing heat…
Driven Geometric Phase Gates with Trapped Ions
A. Lemmer, A. Bermudez, M. B. Plenio
We describe a hybrid laser-microwave scheme to implement two-qubit geometric phase gates in crystals of trapped ions. The proposed gates can attain errors below the fault-tolerance…
Spin-Peierls Quantum Phase Transitions in Coulomb Crystals
A. Bermudez, M. B. Plenio
The spin-Peierls instability describes a structural transition of a crystal due to strong magnetic interactions. Here we demonstrate that cold Coulomb crystals of trapped ions prov…
Frustrated Quantum Spin Models with Cold Coulomb Crystals
A. Bermudez, J. Almeida, F. Schmidt-Kaler +2
We exploit the geometry of a zig-zag cold-ion crystal in a linear trap to propose the quantum simulation of a paradigmatic model of long-ranged magnetic frustration. Such a quantum…
