Chiral phonons driven by chiral cavities
V. A. S. V. Bittencourt, N. Shabala, R. M. Geilhufe +1
Lattice vibrations carrying angular momentum give rise to fundamental phenomena such as the phonon Hall effect and the Einstein-de Haas effect, offering new opportunities for manip…
Unifying microscopic theories for the phono-magnetic effect
Natalia Shabala, Finja Tietjen, Ylva Liljegren +1
Phonon angular momentum induces an effective magnetic field, a phenomenon called phono-magnetic effect, which has been measured to vary significantly in size. Here, we compare thre…
Non-Markovian heat production in ultrafast phonon dynamics
Fredrik Erikssonm Yulong Qiao, Erik Fransson, R. Matthias Geilhufe +1
High-intensity THz laser pulses enable the light-mediated control of lattice vibrations by resonantly driving selected phonon modes. On ultrafast timescales, memory effects influen…
Fluctuation-induced quadrupole order in magneto-electric materials
Finja Tietjen, R. Matthias Geilhufe
Phases that go beyond dipolar ordering and into multipolar ordering have recently been observed in magneto-electric materials. The resulting phase diagram is commonly explained usi…
