Powerful method to evaluate the mass gaps of free-particle quantum critical systems
Francisco C. Alcaraz, José A. Hoyos, Rodrigo A. Pimenta
We present a numerical method for the evaluation of the mass gap, and the low-lying energy gaps, of a large family of free-fermionic and free-parafermionic quantum chains. The meth…
Infinite-randomness quantum critical points induced by dissipation
Thomas Vojta, Chetan Kotabage, J. A. Hoyos
We develop a strong-disorder renormalization group to study quantum phase transitions with continuous O symmetry order parameters under the influence of both quenched disorder…
Weakly disordered absorbing-state phase transitions
J. A. Hoyos
The effects of quenched disorder on nonequilibrium phase transitions in the directed percolation universality class are revisited. Using a strong-disorder energy-space renormalizat…
Theory of smeared quantum phase transitions
J. A. Hoyos, Thomas Vojta
We present an analytical strong-disorder renormalization group theory of the quantum phase transition in the dissipative random transverse-field Ising chain. For Ohmic dissipation,…
Effects of dissipation on a quantum critical point with disorder
J. A. Hoyos, Chetan Kotabage, Thomas Vojta
We study the effects of dissipation on a disordered quantum phase transition with O order parameter symmetry by applying a strong-disorder renormalization group to the Landau-…
Local defect in a magnet with long-range interactions
J. A. Hoyos, Thomas Vojta
We investigate a single defect coupling to the square of the order parameter in a nearly critical magnet with long-range spatial interactions of the form , focusing on…
