Over the past few decades, Liquid Argon Time Projection Chambers (LArTPCs) have emerged as a central technology for rare-event detection, due to their calorimetric and imaging capabilities. Adding a magnetic field to LArTPCs would enable charge identification and momentum measurements via curvature. For neutrino experiments, this is crucial for wrong-sign neutrino rejection, electron/positron...

In advanced detectors, we observe events of stored energy releases, as well as energy accumulation and delayed release dynamics. Spontaneous burst emission of electrons, photons, phonons, and quasiparticles produces excess backgrounds in different dark matter detectors. Accumulation of unextracted charges on the liquid-gas interface in large dual-phase detectors can lead to surface...
