Quantum Squeezing Enhanced Photothermal Microscopy
Pengcheng Fu, Xiao Liu, Siming Wang +10
Label-free optical microscopy through absorption or scattering spectroscopy provides fundamental insights across biology and materials science, yet its sensitivity remains fundamen…
Topological Phase Transition and Geometrical Frustration in Fourier Photonic Simulator
Yuxuan Sun, Weiru Fan, Xingqi Xu +2
XY models with continuous spin orientation play a pivotal role in understanding topological phase transitions and emergent frustration phenomena, such as superconducting and superf…
Realizing the Haldane Model in Thermal Atoms
Jiefei Wang, Jianhao Dai, Ruosong Mao +7
Topological materials hold great promise for developing next-generation devices with transport properties that remain resilient in the presence of local imperfections. However, the…
Gate-tunable hot electron extraction in a two-dimensional semiconductor heterojunction
Chenran Xu, Chen Xu, Jichen Zhou +9
Hot carrier solar cells (HCSCs), harvesting excess energy of the hot carriers generated by above-band-gap photoexcitation, is crucial for pushing the solar cell efficiency beyond t…
