Topological surface phonons modulate thermal transport in semiconductor thin films
Zhe Su, Shuoran Song, Qi Wang +1
While phonon topology in crystalline solids has been extensively studied, its influence on thermal transport-especially in nanostructures-remains elusive. Here, by combining first-…
Polarization-resolved measurement of forward volume spin waves by micro-focused Brillouin light scattering
Krzysztof Szulc, Mengying Guo, OndÅej Wojewoda +7
We show how the micro-focused BLS signal of forward volume spin waves is formed and why it remains observable despite symmetry-based "suppression" expectations. A reciprocity-theor…
Stimulated Magnonic Frequency Combs
Xueyu Guo, Tianci Gong, Guibin Lan +5
Magnonic frequency combs, characterized by a series of discrete frequency lines, have emerged as a promising frontier in magnon spintronics, with potential applications in advanced…
Accelerating discovery of infrared nonlinear optical materials with large shift current via high-throughput screening
Aiqin Yang, Dian Jin, Mingkang Liu +4
Discovering nonlinear optical (NLO) materials with strong shift current response, particularly in the infrared (IR) regime, is essential for next-generation optoelectronics yet rem…
Ultrafast propagation of magnon-polaritons
OndÅej Wojewoda, Miela J. Gross, Jan KlÃma +11
The manipulation of magnetization lies at the heart of spintronic and magnonic technologies, with the ultimate performance of such systems limited by the velocity at which magnetic…
Exchange spin-wave propagation in Ga:YIG nanowaveguides
Andrey A. Voronov, Khrystyna O. Levchenko, Roman Verba +7
Spin-wave-based computing has emerged as a promising approach to overcome the fundamental limitations of CMOS technologies. However, the increasing demand for device miniaturizatio…
