New Constraints on Dark Photon Dark Matter with a Millimeter-Wave Dielectric Haloscope
Guoqing Wei, Diguang Wu, Runqi Kang +4
Dark matter remains one of the most profound and unresolved mysteries in modern physics. To unravel its nature, numerous haloscope experiments have been implemented across various…
Vacuum Torque Without Anisotropy: Switchable Casimir Torque Between Altermagnets
Zixuan Dai, Qing-Dong Jiang
Casimir torque is conventionally associated with explicit breaking of rotational symmetry, arising from material dielectric anisotropy, geometric asymmetry, or externally applied f…
Searching Repulsive Casimir Forces Between Magneto-Electric Materials
Zixuan Dai, Qing-Dong Jiang
The Casimir effect, arising from vacuum quantum fluctuations, plays a fundamental role in the development of modern quantum electrodynamics. In parallel, the field of condensed mat…
Engineering Ponderomotive Potential for Realizing and Bosonic Josephson Junctions
Jiadu Lin, Qing-Dong Jiang
We study the ponderomotive potential of a bosonic Josephson junction periodically modulated by a high-frequency electromagnetic field. Within the small population difference approx…
