Equilibrium Partition Function of Non-Relativistic CFTs in Harmonic Trap

This paper investigates the equilibrium partition function of non-relativistic conformal field theories in harmonic traps, revealing that the logarithm of the partition function exhibits universal simple poles in the difference between the squared trapping frequency and squared angular velocities, with residues determined by the equation of state in the hydrodynamic regime and by specific thermodynamic variables in the large-angular-momentum limit.

An asymptotic proof of the classical log soft graviton theorem

This paper presents a fully covariant derivation of the classical log soft graviton theorem using Einstein equations and matching conditions across timelike, spatial, and null infinity, demonstrating that the asymmetry between future and past hard components arises from a discontinuity in the gravitational field at spatial infinity.

A Swampland-modified Hod bound for charged black holes with exotic matter

This paper investigates the quasinormal modes, stability, and observational signatures of charged black holes surrounded by quintessence and a cloud of strings, ultimately deriving a Swampland-modified Hod bound that ensures consistency between black hole thermodynamics, observable properties, and quantum gravity constraints.

The scheme independent 3-sphere free energy is not a monotone F-function

This paper demonstrates that while the scheme-independent three-sphere free energy decreases locally under relevant scalar deformations at conformal fixed points, it fails to be a globally monotone F-function along the full renormalization-group flow, as evidenced by its non-monotonic behavior in the massive scalar theory.

Kaluza-Klein mode mixing in braneworlds: constraints on scalar absorption and physical degrees of freedom

This paper investigates Kaluza-Klein mode mixing in braneworlds, demonstrating that while gauge invariance is preserved, vector-scalar mixing imposes stringent constraints on warp factors and dynamically shifts vector masses, ultimately leaving a residual set of physical massive scalar modes in (4+2)-dimensional models.

Quasinormal modes and greybody factors of magnetically charged de Sitter black holes probed by massless external fields in Einstein Euler Heisenberg gravity

This paper investigates the perturbation dynamics of massless scalar and electromagnetic fields on magnetically charged de Sitter black holes in Einstein-Euler-Heisenberg gravity by calculating quasinormal frequencies and greybody factors to analyze the effects of magnetic charge, cosmological constant, coupling parameter, and multipole number using the asymptotic iteration, WKB, and Bernstein spectral methods.

Non-invertible symmetries and selection rules for RG flows of coset models

This paper introduces a method utilizing local data to classify superselection sectors and topological defect lines in two-dimensional conformal field theories, thereby establishing a unified framework for deriving selection rules governing renormalization group flows in coset and parafermion models.

Dynamics and interaction of solitons in the BPS limit and their internal modes

This thesis investigates the dynamics and interactions of solitons (kinks, oscillons, vortices, and sphalerons) in one- and two-dimensional models by employing effective collective coordinate models to introduce radiation modes, generalize moduli space metrics with vibrational degrees of freedom, identify semi-BPS sphalerons, and propose a dynamic stabilization mechanism driven by internal modes.

Duality and Dilaton

This paper reviews and elaborates on the transformation of the dilaton under target space duality, demonstrating that the standard one-loop transformation law requires modification at two-loop and higher orders, a finding illustrated through time-dependent cosmological solutions.

Operator Renormalization using Emergent Supersymmetries

This paper proposes a mechanism to apply supersymmetric Ward identities in non-supersymmetric theories to streamline calculations, demonstrating its effectiveness through operator renormalization in the Gross-Neveu-Yukawa model as a precursor to future applications in Quantum Chromodynamics.

Scheme dependence and instability of double-trace deformations for gauge fields in AdS $_5$

This paper demonstrates that introducing dynamical gauge fields in the boundary theory via double-trace deformations of bulk gauge fields in asymptotically AdS $_5$ spacetime leads to tachyon and ghost instabilities caused by logarithmic boundary behavior and scheme-dependent ambiguities, a finding confirmed through both analytical and numerical analyses of various holographic models.

Photon spheres and bulk probes in $\text{AdS}_3$ / $\text{CFT}_2$ : the quantum BTZ black hole

This paper provides an exhaustive analysis of boundary-anchored geodesics in the three-dimensional quantum BTZ black hole and its charged counterpart, establishing conditions for their existence and investigating the relationship between photon rings and the reality of timelike entanglement entropy in the context of the AdS $_3$ /CFT $_2$ correspondence.

Hydrodynamics as cospans of field theories into the BF theory

This paper proposes a categorical framework for hydrodynamics by modeling the approximation of a microscopic theory as a cospan of differential graded manifolds that connects the microscopic and hydrodynamic descriptions through a $BF$ theory encoding the conservation laws of currents.

Branched polymers with loops coupled to the critical Ising model

This paper proposes a string field theory for branched polymers with loops coupled to the critical Ising model, demonstrating that its non-perturbative partition function satisfies a third-order linear differential equation and a Wheeler-DeWitt equation derived via both matrix model loop equations and stochastic quantization.

Extreme mass ratio head-on collisions of black holes in Einstein-scalar-Gauss-Bonnet theory

This paper extends ray-tracing techniques to analyze head-on collisions of non-spinning hairy black holes in Einstein-scalar-Gauss-Bonnet gravity, finding that while most coupling functions prolong the merger duration compared to general relativity, an exponential coupling can shorten it, with both merger duration and area increment generally tracking the behavior of the small black hole's photon ring.

A conjecture on the lower bound of the length-scale critical exponent $\nu$ at continuous phase transitions

This paper conjectures a lower bound for the critical exponent $\nu$ in continuous phase transitions described by Landau-Ginzburg-Wilson $\Phi^4$ theories, proposing the inequality $\nu \ge (2-\eta)^{-1}$ (which implies $\nu \ge 1/2$ for unitary theories) based on the condition $\Delta_\varepsilon \ge 2 \Delta_\varphi$ , a hypothesis supported by arguments from lattice models, $\epsilon$ -expansions, and exact two-dimensional conformal field theory results.
