Magnon-phonon interactions in magnetic insulators
Simon Streib, Nicolas Vidal-Silva, Ka Shen +1
We address the theory of magnon-phonon interactions and compute the corresponding quasi-particle and transport lifetimes in magnetic insulators with focus on yttrium iron garnet at…
Hard-core boson approach to the spin-1/2 triangular-lattice antiferromagnet CsCuCl at finite temperatures in magnetic fields higher than the saturation field
Simon Streib, Peter Kopietz
We study the high magnetic field regime of the antiferromagnetic insulator CsCuCl by expressing the spin-1/2 operators in the relevant Heisenberg model in terms of hard-cor…
Majorana spin liquid and dimensional reduction in Cs2CuCl4
Tim Herfurth, Simon Streib, Peter Kopietz
The low-temperature behavior of the magnetic insulator Cs2CuCl4 can be modeled by an anisotropic triangular lattice spin-1/2 Heisenberg antiferromagnet with two different exchange…
Solution of the Anderson impurity model via the functional renormalization group
Simon Streib, Aldo Isidori, Peter Kopietz
We show that the functional renormalization group is a numerically cheap method to obtain the low-energy behavior of the Anderson impurity model describing a localized interacting…
