Monte-Carlo simulations of the dissipative random transverse-field Ising chain
Manal Al-Ali, Thomas Vojta
We study the influence of Ohmic dissipation on the random transverse-field Ising chain by means of large-scale Monte-Carlo simulations. To this end, we first map the Hamiltonian on…

Percolation transition in quantum Ising and rotor models with sub-Ohmic dissipation
Manal Al-Ali, José A. Hoyos, Thomas Vojta
We investigate the influence of sub-Ohmic dissipation on randomly diluted quantum Ising and rotor models. The dissipation causes the quantum dynamics of sufficiently large percolat…

Quantum phase transition of the sub-Ohmic rotor model
Manal Al-Ali, Thomas Vojta
We investigate the behavior of an -component quantum rotor coupled to a bosonic dissipative bath having a sub-Ohmic spectral density with . With increasi…
