Infrared properties of two-dimensional nonlinear models at nonzero angles
Philippe Lecheminant, Yuya Tanizaki, Keisuke Totsuka
A general strategy is proposed to explore the low-energy properties of two-dimensional nonlinear models with terms. We demonstrate its application to nonlinear models w…
Non-Landau quantum phase transition in modulated SU(N) Heisenberg spin chains
Sylvain Capponi, Lukas Devos, Philippe Lecheminant +2
We investigate the nature of the quantum phase transition in modulated SU(N) Heisenberg spin chains. In the odd-N case, the transition separates a trivial non-degenerate phase to a…
Computational Characterization of Symmetry-Protected Topological Phases in Open Quantum Systems
Riku Masui, Keisuke Totsuka
It is a challenging problem to correctly characterize the symmetry-protected topological (SPT) phases in open quantum systems. As the measurement-based quantum computation (MBQC) u…
Lieb-Schultz-Mattis constraints for the insulating phases of the one-dimensional SU() Kondo lattice model
Philippe Lecheminant, Keisuke Totsuka
The nature of the insulating phases of the SU()-generalization of the one-dimensional Kondo lattice model is investigated by means of non-perturbative approaches. By extending t…
