All-optical nonreciprocity due to valley polarization in transition metal dichalcogenides
Yuma Kawaguchi, Sriram Guddala, Kai Chen +3
Nonreciprocity and nonreciprocal optical devices play a vital role in modern photonic technologies by enforcing one-way propagation of light. Most nonreciprocal devices today are m…
Fourth-Order Topological Insulator via Dimensional Reduction
Kai Chen, Matthew Weiner, Mengyao Li +3
The properties of topological systems are inherently tied to their dimensionality. Higher-dimensional physical systems exhibit topological properties not shared by their lower dime…
Dual-band in situ molecular spectroscopy using single-sized Al-disk perfect absorbers
Thang Duy Dao, Kai Chen, Tadaaki Nagao
In this manuscript, we have demonstrated that the antenna-enhanced infrared vibrational spectroscopy can be a powerful platform for high-sensitivity detection of ultrathin layer of…
Violation of the virial theorem and generalized equipartition theorem for logarithmic oscillators serving as a thermostat
Kai Chen, Dahai He, Hong Zhao
A logarithmic oscillator has been proposed recently to serve as a thermostat recently since it has a peculiar property of infinite heat capacity according to the virial theorem. In…
Enhancement of Thermally Injected Spin Current through an Antiferromagnetic Insulator
Weiwei Lin, Kai Chen, Shufeng Zhang +1
We report large enhancement of thermally injected spin current in normal metal (NM)/antiferromagnet(AF)/yttrium iron garnet(YIG), where a thin AF insulating layer of NiO or CoO can…
Comment on "Correlation between Bulk Thermodynamic Measurements and the Low-Temperature-Resistance Plateau in SmB6"
Kai Chen, Jean-Paul Kappler
Low-temperature-resistivity plateau observed in single crystal,which is due to surface, not bulk, conduction has been confirmed from electrical transport measurements.…
