Entanglement flow in the Kane-Fisher quantum impurity problem
Chunyu Tan, Yuxiao Hang, Stephan Haas +1
The problem of a local impurity in a Luttinger liquid, just like the anisotropic Kondo problem (of which it is technically a cousin), describes many different physical systems. As…
Universal phase diagram of disordered bosons from a doped quantum magnet
Rong Yu, Stephan Haas, Tommaso Roscilde
A quantum particle cannot in general diffuse through a disordered medium because of its wavelike nature, but interacting particles can escape localization by collectively percolati…
Field-Induced Magnetic Order in Quantum Spin Liquids
Stefan Wessel, Maxim Olshanii, Stephan Haas
We study magnetic field-induced three-dimensional ordering transitions in low-dimensional quantum spin liquids, such as weakly coupled, antiferromagnetic spin-1/2 Heisenberg dimers…
Order by disorder from non-magnetic impurities in a two-dimensional quantum spin liquid
S. Wessel, B. Normand, M. Sigrist +1
We consider doping of non-magnetic impurities in the spin-1/2, 1/5-depleted square lattice. This structure, whose undoped phase diagram offers both magnetically ordered and spin-li…
