• Abstract: We show that the spatial structure of electromagnetic vacuum fluctuations, predicted by quantum electrodynamics, can be indirectly observed using thermal noise at radio frequencies. Using simple lab equipment like coaxial cables and RF splitters, we detect a clear suppression of thermal noise near conducting boundaries, mirroring the expected modulation of vacuum modes. This provides accessible, experimental evidence for quantum vacuum behavior without requiring advanced optics or cryogenics.

• Sensing atomic superfluid rotation beyond the standard quantum limit [9.168807394388612]
  Atomic superfluids formed using Bose-Einstein condensates (BECs) in a ring trap are being investigated in the context of superfluid hydrodynamics, quantum sensing and matter-wave interferometry. Recent studies have proposed coupling the ring BEC to optical cavity modes carrying orbital angular momentum to make minimally destructive measurements of the condensate rotation. We present a detailed theoretical analysis to demonstrate that the use of squeezed light and backaction evasion techniques allows the angular momentum of the condensate to be sensed with noise well below the standard quantum limit.

  We introduce an operational way to distinguish between the overall shift in the pulse wavepacket and its genuine deformation after propagation. We then apply our technique to quantum states of photons that are coherent in the frequency degree of freedom. We find that the quantum coherence initially present can enhance the deformation induced by propagation in a curved background.
