A tensor network formulation of Lattice Gauge Theories based only on symmetric tensors
Manu Canals, Natalia Chepiga, Luca Tagliacozzo
The Lattice Gauge Theory Hilbert space is divided into gauge-invariant sectors selected by the background charges. Such a projector can be directly embedded in a tensor network ans…
The quantum Kibble-Zurek mechanism: the role of boundary conditions, endpoints and kink types
Jose Soto Garcia, Natalia Chepiga
Quantum phase transitions are characterised by the universal scaling laws in the critical region surrounding the transitions. This universality is also manifested in the critical r…
Numerical investigation of quantum phases and phase transitions in a two-leg ladder of Rydberg atoms
Jose Soto, Natalia Chepiga
Experiments on chains of Rydberg atoms appear as a new playground to study quantum phase transitions in 1D. As a natural extension, we report a quantitative ground-state phase diag…
Probing universal critical scaling with scan-DMRG
Natalia Chepiga
We explore the universal signatures of quantum phase transitions that can be extracted with the density matrix renormalization group (DMRG) algorithm applied to quantum chains with…
transitions in quantum loop models on a zig-zag ladder
Bowy M. La Rivière, Natalia Chepiga
We study the nature of quantum phase transitions out of ordered phases in quantum loop models on a zig-zag ladder. We report very rich critical behavior that include…
Resolving chiral transitions in Rydberg arrays with quantum Kibble-Zurek mechanism and finite-time scaling
Jose Soto Garcia, Natalia Chepiga
The experimental realization of the quantum Kibble-Zurek mechanism in arrays of trapped Rydberg atoms has brought the problem of commensurate-incommensurate transition back into th…
Realization of Wess-Zumino-Witten transitions with levels and in a frustrated spin-3 chain
Natalia Chepiga
We study dimerization transitions in a frustrated spin-3 chain with next-nearest neighbor and three-site interactions. We show that two independent coupling constants of the model…
