Field-induced coherence and Fröhlich condensation in hydrated DNA

Hydrated DNA confined in quasi-two-dimensional water layers exhibits macroscopic quantum coherence at ambient conditions under moderate magnetic fields. At 6 °C and low DNA concentration (100 ng/μL), we observe a sharp transverse voltage jump (∼37 mV) near 100 mT, followed by five regular oscillations (>20 mV), indicating an earlier onset of coherence compared to room-temperature transitions (∼0.5 T) at higher DNA concentrations (1000 ng/μL). These features suggest the formation of a Fröhlich-like condensate stabilized by field-induced energy localization. The system's response unfolds as geometric 'Riemann slices,' coherence domains activated sequentially by the magnetic field. The nearly flat longitudinal voltage confirms a selective transverse transport regime. Fourier analysis reveals distinct low-frequency peaks, reflecting regular internal modulation within the coherent state. Together with earlier findings of Landau quantization and ultra-weak photon emission, our results support a hierarchical model of vibrational condensation and geometric coherence in DNA–water systems, with potential implications for bioenergetics and magnetosensitivity.
