“Intrinsic Josephson Dynamics in Bi-2212 as a Phenomenological
Testbed for Information-Gauge Fields:
Constraints on Λµ, Entropy Production, and Odd-in-B Asymmetry” (J. H. Lee, 2025).

The code in this package reproduces all main figures of the paper, including:

• Figure 1: Schematic of Bi-2212 as an intrinsic Josephson junction (IJJ) stack and its IG–RUEQFT interpretation.

• Figure 2: Coupled sine–Gordon model for an N-junction stack and representative multi-branch I–V characteristics.

• Figure 3: Annular Bi-2212 junction geometry, information Wilson loop interpretation, and resonance-step illustration.

• Figure 4: Back-bending of I–V curves under long vs short current pulses, and its connection to entropy production.

• Figure 5: Flux-flow branch and Fiske-like steps used to extract the Swihart velocity and information-mode spectrum.

• Figure 6: Vortex-lattice regimes, 3D–to–quasi-2D dimensional reduction, and schematic B–I phase diagram.

• Figure 7: ZFC/FC hysteresis in I–V curves and its information-memory interpretation.

• Figure 8: Field-inversion asymmetry I(V,+B)≠−I(V,−B)I(V,+B)\neq -I(V,-B)I(V,+B)=−I(V,−B) and constraints on CP-odd information couplings.

• Figure 9: Random Telegraph Signals (RTS), dwell-time statistics, and the double-well information-potential picture.

• Figure 10: Summary of empirical constraints on information-gauge parameters (τinfo\tau_{\rm info}τinfo, δ1\delta_1δ1, χ\chiχ, goddg_{\rm odd}godd, U/kBTU/k_BTU/kBT).

• Figure 11: Conceptual outlook figure situating Bi-2212 IJJs as a testbed for information-gauge-inspired physics.

Where applicable, the scripts generate schematic diagrams and re-plot digitized data derived from the original Bi-2212 experiments reported in:

• J. Lee, Magnetic Field Effect of Bi2Sr2CaCu2O8+δ High Temperature Superconductor Intrinsic Josephson Junctions, Ph.D. thesis (2000).

• Associated presentation slides (Lee, 2000).

The archive is intended to support full reproducibility of the figures and to provide a transparent reference implementation for researchers who wish to:

1. Recreate or modify the original figures for independent analysis or pedagogical use.

2. Adapt the plotting and schematic templates to related studies of intrinsic Josephson junctions and vortex dynamics.

3. Extend the IG–RUEQFT–inspired phenomenological analysis to other superconducting or strongly correlated platforms.
