标题： Giant thermal modulation via a semiconductor-superconductor photonic field-effect heat transistor

摘要： 我们展示了一种在场效应可控制的半导体-超导体混合结构中热调制的突破性演示，其中加热机制仅是辐射性的。 该结构由两个通过$\sim 1$ mm 分离的库，并通过一个完全非 galvanic 的电路相互连接，从而实现从热库到冷库的黑体辐射传输。 我们的器件利用超导 Josephson 场效应晶体管，在电路中实现无磁场的栅极可调热流调控。 虽然先前的研究表明静电调制热传输特性的潜力，但我们的框架展示了高达$\sim 45$ mK 的温度调制，比先前发现超过一个数量级。 此外，它在浴温为$30$ mK 时证明了热转移阻抗为$\sim 20$ mK/V。 此类系统的发展在推进量子芯片和辐射传感器中的热量管理和路由方面具有巨大的前景，因为它能够在热源远离且非 galvanically 耦合的情况下，对指定结构的热流实现精确的非本地控制。 显示英文摘要

摘要： We present a groundbreaking demonstration of thermal modulation in a field-effect-controllable semiconductor-superconductor hybrid structure, wherein the heating mechanism is exclusively radiative. The architecture comprises two reservoirs separated by $\sim 1$ mm and interconnected via a completely non-galvanic electrical circuit, enabling the transfer of black-body radiation from the hot to the cold reservoir. Our device utilizes a superconducting Josephson field-effect transistor to achieve magnetic-field-free gate-tunable regulation of heat currents within the circuit. While prior studies have indicated the potential for electrostatic modulation of thermal transport properties, our framework demonstrates a temperature modulation of up to $\sim 45$ mK, exceeding prior findings by more than an order of magnitude. Furthermore, it proves a thermal transimpedance of $\sim 20$ mK/V at a bath temperature of $30$ mK. The development of such systems holds substantial promise for advancing heat management and routing in quantum chips and radiation sensors, as it enables precise nonlocal control of heat flow towards a designated structure, even when the heat source is distant and non-galvanically coupled.
