Higgs time crystal in a high-T_{c} superconductor
Physical Review Research, 2020 We propose to induce a time-crystalline state in a high-T_{c} superconductor, by optically driving a sum resonance of the Higgs mode and a Josephson plasma mode. The generic cubic process that couples these fundamental excitations converts driving of the

Unified subharmonic oscillation conditions for peak or average current mode control [PDF]
International Journal of Circuit Theory and Applications, 2014 SummaryThis paper is an extension of the author's recent research in which only buck converters were analyzed. Similar analysis can be equally applied to other types of converters. In this paper, a unified model is proposed for buck, boost, and buck–boost converters under peak or average current mode control to predict the occurrence of subharmonic ...

The Milankovitch Theory Revisited to Explain the Mid-Pleistocene and Early Quaternary Transitions
AtmosphereThe theory of orbital forcing as formulated by Milankovitch involves the mediation by the advance (retreat) of ice sheets and the resulting variations in terrestrial albedo. This approach poses a major problem: that of the period of glacial cycles, which

A Reconfigurable Low-Voltage and Low-Power Millimeter-Wave Dual-Band Mixer in 65-nm CMOS
IEEE Access, 2019 In this paper, we propose, investigate, and demonstrate a reconfigurable low-voltage and low-power millimeter-wave mixer in a 65-nm CMOS, which can be switched as either a subharmonic mixer (SHM) or a fundamental mixer (FM) for the dual-band applications.
