Field induced spontaneous quasiparticle decay and renormalization of quasiparticle dispersion in a quantum antiferromagnet
Tao Hong, Y. Qiu, M. Matsumoto +7
The notion of a quasiparticle, such as a phonon, a roton, or a magnon, is used in modern condensed matter physics to describe an elementary collective excitation. The intrinsic zer…

Linked-cluster expansions for quantum magnets on the hypercubic lattice
K. Coester, D. G. Joshi, M. Vojta +1
For arbitrary space dimension we investigate the quantum phase transitions of two paradigmatic spin models defined on a hypercubic lattice, the coupled-dimer Heisenberg model a…

Emergence of a 2d macro-spin liquid in a highly frustrated 3d quantum magnet
Tycho S. Sikkenk, Kris Coester, Lars Fritz +1
The classical Ising model on the frustrated 3d swedenborgite lattice has disordered spin liquid ground states for all ratios of inter- and intra-planar couplings. Quantum fluctuati…
