Nonsymmorphic spin-space cubic groups and SU(2) conformal invariance in one-dimensional spin-1/2 models
Wang Yang, Alberto Nocera, Chao Xu +1
Recently, extended gapless phases with emergent SU(2) conformal invariance occupying finite regions in the phase diagrams have been found in one-dimensional spin-1/2 models wit…
Qubit-oscillator relationships in the open quantum Rabi model: the role of dissipation
G. Di Bello, L. M. Cangemi, V. Cataudella +3
Using a dissipative quantum Rabi model, we study the dynamics of a slow qubit coupled to a fast quantum harmonic oscillator interacting with a bosonic bath from weak to strong and…
Counter-rotating spiral, zigzag, and 120 orders from coupled-chain analysis of Kitaev-Gamma-Heisenberg model, and relations to honeycomb iridates
Wang Yang, Alberto Nocera, Chao Xu +2
We study the nearest neighboring spin-1/2 Kitaev-Heisenberg-Gamma () model on the honeycomb lattice in the parameter region of ferromagnetic (FM) Kitaev and antiferromagnetic…
Signatures of Dissipation Driven Quantum Phase Transition in Rabi Model
G. De Filippis, A. de Candia, G. Di Bello +6
By using worldline Monte Carlo technique, matrix product state and a variational approach à la Feynman, we investigate the equilibrium properties and relaxation features of the dis…
Root-N Krylov-space correction-vectors for spectral functions with the density matrix renormalization group
Alberto Nocera, Gonzalo Alvarez
We propose a method to compute spectral functions of generic Hamiltonians using the density matrix renormalization group (DMRG) algorithm directly in the frequency domain, based on…
