摘要:

超轻玻色子暗物质(UBDM)可以用一个在玻色子康普顿频率附近振荡的经典波状场来描述。如果用于直接探测UBDM相互作用的测量方案对场的二次方信号敏感,那么信号中就存在一个近零频(直流)分量。因此,一个具有给定有限带宽的探测器可以用来搜寻康普顿频率比其带宽高出许多个数量级的玻色子。这开启了一种类似于Hanbury Brown和Twiss强度干涉测量的探测方案的可能性。假设UBDM在银河系引力势中已经维里化,随机速度会产生与康普顿频率的微小偏差。这些偏差导致强度在由动能展宽决定的时间尺度上产生随机涨落。为了抑制普遍存在的本地低频噪声,可以使用传感器网络通过测量传感器之间的互相关来搜寻随机强度涨落。这种方法本质上是宽带的,因为大范围的康普顿频率会在传感器带宽内产生可以同时搜寻的近零频分量。利用现有传感器网络进行的测量具有足够的灵敏度,可以搜寻实验上尚未探索的参数空间。

英文摘要:

Ultralight bosonic dark matter (UBDM) can be described by a classical wave-like field oscillating near the Compton frequency of the bosons. If a measurement scheme for the direct detection of UBDM interactions is sensitive to a signature quadratic in the field, then there is a near-zero-frequency (dc) component of the signal. Thus, a detector with a given finite bandwidth can be used to search for bosons with Compton frequencies many orders of magnitude larger than its bandwidth. This opens the possibility of a detection scheme analogous to Hanbury Brown and Twiss intensity interferometry. Assuming that the UBDM is virialized in the galactic gravitational potential, the random velocities produce slight deviations from the Compton frequency. These result in stochastic fluctuations of the intensity on a time scale determined by the spread in kinetic energies. In order to mitigate ubiquitous local low-frequency noise, a network of sensors can be used to search for the stochastic intensity fluctuations by measuring cross-correlation between the sensors. This method is inherently broadband, since a large range of Compton frequencies will yield near-zero-frequency components within the sensor bandwidth that can be searched for simultaneously. Measurements with existing sensor networks have sufficient sensitivity to search experimentally unexplored parameter space.
