abstract
This is an introduction to the method of effective field theory. As an application, I derive the effective field theory of low energy excitations in a conductor, the Landau theory of Fermi liquids, and explain why the high-$T_c$ superconductors must be described by a different effective field theory.

Symmetry-Enforced Fermi Surfaces
A noncompact Lie group symmetry generated by U(1) fermion number and Majorana translations enforces Fermi surfaces that generically have at least two noncontractible components in d-dimensional Bravais lattices.

Symmetry-based nonlinear fluctuating hydrodynamics in one dimension
Symmetry and conservation laws alone yield nonlinear fluctuating hydrodynamics equations whose sound and heat modes both flow to a KPZ fixed point with dynamical exponent 3/2, confirmed by simulations matching the Pra...

Field Theory of Superconductor and Charged Vortex
The paper proposes a Lagrangian for superconductivity with a phonon field and shows that at two critical couplings, charged vortices saturate a BPS bound at the type I/II boundary.

Renormalization-group approach to the Kohn-Luttinger superconductivity: Amplification of the pairing gap from $\ell^4$ to $\ell$
The renormalization group with the zero-sound diagram predicts the Kohn-Luttinger pairing gap exponent scales as -ℓ instead of the standard -ℓ^4.

Probing Gravity -- Fundamental Aspects of Metric Theories and their Implications for Tests of General Relativity
Gravitational wave memory is shown to arise naturally from the Isaacson backreaction formalism in general metric theories of gravity, unifying null and ordinary memory and providing a memory formula valid beyond GR.

The negativity contour: a quasi-local measure of entanglement for mixed states
The authors define a computable negativity contour via a derivative of logarithmic negativity, verify it against a Gaussian ansatz, and apply it to Fermi surfaces, holographic non-Fermi liquids, and thermalization.

Four-Fermion Condensates in Curved Spacetimes: A Functional Approach
A one-loop functional derivation gives the local effective action and FLRW energy-momentum tensor for a scalar-channel NJL condensate in curved spacetime, reproducing flat-space mean-field results in the constant-cond...

The Coherence Principle: A Falsifiable Prior for Model Selection from the Grammar of Theories
The Coherence Principle supplies a falsifiable prior for Bayesian model selection by converting compatibility with a theory's validated grammar into prior weights via a maximum-entropy exponential controlled by one parameter.

Reduce dimensional quantum criticality for Non-Fermi liquids
A reduced-dimension model places bosons in (d+1) dimensions and fermions in d dimensions to make perturbative RG analysis of NFL physics more tractable by taming logarithmic and higher divergences.

Wilsonian renormalisation group and thermal field theory in the Schwinger-Keldysh closed-time-path formalism
A one-loop Schwinger-Keldysh Wilsonian RG calculation generates a dissipative cross-coupling between time branches and predicts two reduced-space fixed points in d=4, related to the Gaussian and Wilson-Fisher fixed points.

Non-Fermi liquid induced by U(1) gauge field interactions: a functional renormalization group analysis
Functional RG with modified Ward-Takahashi identities applied to a 2D Fermi gas coupled to a U(1) gauge field gives a non-Fermi liquid fixed point with z_A=2 and Σ(ω)∼ω^{1/2}, differing from the standard z_A=3, ω^{2/3}.

Emergence of Fermi-liquid and BCS physics in overdoped cuprates
Overdoped cuprates, which currently look exotic, may be ordinary Fermi-liquid/BCS superconductors once alloy disorder is accounted for, with clean-material tests proposed.

Effective Field Theory of Superconductivity
The paper proposes an EFT of conventional superconductivity and a new critical phonon coupling g=q/√ε0 that cancels Cooper pair Coulomb repulsion, claimed to be the condition for superconductivity.

Generative diffusion model with inverse renormalization group flows
RGDM generates data by reversing renormalization-group-style coarse-graining, using a colored-noise schedule and projection layers to sample coarse-to-fine, and outperforms a vanilla DDPM on protein and image benchmarks.

Effective Field Theories for Material Media
Spacetime-symmetry-breaking Goldstone EFTs systematically describe bulk and localized excitations of solids, fluids, and superfluids, with new thermodynamic identifications and corrected scattering rates.

From Nuclear Matter with Quenched $g_A$ to Compact-Star Matter with a Signal for Emergent Hidden Scale Symmetry
The paper argues that quenched g_A ≈ 1 in nuclei and the pseudo-conformal sound speed v_s^2/c^2 ≈ 1/3 in compact stars are parallel signals of one emergent hidden scale symmetry.

In-In EFT
An EFT for in-in correlators is defined by matching the full theory's real-time correlators, leading to operators with boundary terms and odd time derivatives.
