Scale-Dependent Loop Corrections to the Inflationary Power Spectrum

This paper establishes a consistent renormalization framework within the Effective Field Theory of inflation that successfully cancels ultraviolet divergences and tadpoles for scale-dependent backgrounds with strong de Sitter symmetry breaking, demonstrating that the renormalized one-loop power spectrum vanishes at both large and small scales for resonant and sharp features while preserving perturbativity.

Non-Commutative Phase-Space Effects in Fermionic String Theory

This paper investigates free open fermionic strings on a non-commutative phase space, demonstrating that while non-commutativity initially introduces anomalies, breaks Lorentz symmetry, and yields a non-diagonal mass operator, these issues can be resolved by redefining the Fock space and imposing specific constraints on the non-commutativity parameters to restore the standard spectrum and enable the GSO projection.

Non-hyperbolic 3-manifolds and 3D field theories for 2D Virasoro minimal models

This paper utilizes 3D-3D correspondence to construct 3D bulk field theories dual to general Virasoro minimal models, distinguishing between unitary cases that flow to topological field theories and non-unitary cases that flow to rank-0 superconformal field theories, with explicit descriptions provided via T[SU(2)]T[SU(2)] theories and verified through partition function computations.

Generic deformation channels for critical Fermi surfaces including the impact of collisions

This paper extends the analysis of critical Fermi surface deformations at an Ising-nematic quantum critical point by employing quantum Boltzmann equations that include collision effects, revealing that while bosonic dynamics do not alter the solutions, the system supports a robust zero-sound mode and an infinite family of discrete higher-order harmonic modes alongside a continuous particle-hole band.

Shear Viscosity and Electrical Conductivity of Rotating Nuclear Medium in Hadron Resonance Gas and Nambu-Jona Lasinio Models

This paper investigates how rotation influences the anisotropic shear viscosity and electrical conductivity of strongly interacting matter by employing kinetic theory within Hadron Resonance Gas and Nambu-Jona-Lasinio models, revealing that rotation suppresses chiral condensates, generates a sizable Hall-like conductivity, and reduces transport coefficients relative to isotropic cases.
