Area of Science:

  • Condensed matter physics
  • Quantum mechanics
  • Materials science

Background:

  • Dielectric properties of amorphous solids are typically independent of magnetic fields at low temperatures.
  • Quantum tunneling systems in glasses exhibit unique low-temperature behaviors.

Purpose of the Study:

  • To investigate the influence of magnetic fields on the dielectric response of barium alumosilicate glass at cryogenic temperatures.
  • To explore potential quantum effects related to electromagnetic flux in this material.

Main Methods:

  • Experiments conducted below 100 milliKelvin (mK).
  • Measurement of dielectric response in the presence of varying magnetic fields.
  • Analysis of dielectric saturation and resonant regime oscillations.

Main Results:

  • Dielectric response became sensitive to magnetic fields below 100 mK, contrary to expectations.
  • Weak magnetic fields lifted dielectric saturation.
  • Oscillations in dielectric response were observed in the low-temperature resonant regime.

Conclusions:

  • The observed phenomena suggest quantum effects of electromagnetic flux.
  • A proposed mechanism involves magnetic induction violating time-reversal invariance, causing flux periodicity in tunneling system energy levels.
  • Low-temperature interactions between tunneling systems enhance these effects, making them measurable.
