A common and effective method for calculating the steady-state distribution of a process under stochastic resetting is the renewal approach that requires only the knowledge of the reset-free propagator of the underlying process and the resetting time

Using standard kinetic equations, we show that the thermal equilibrium between conduction electrons and phonons is unstable when the renormalized electron-phonon coupling exceeds a certain threshold. We prove that negative electronic specific heat, $

The dispersionless limit of the standard Eliashberg theory of superconductivity is studied. The effective electron-electron interactions are mediated by Einstein phonons of frequency $\Omega>0$, equipped with electron-phonon coupling strength $\lambd

The standard Eliashberg theory of superconductivity is studied. The effective electron-electron interactions are mediated by dispersive phonons, with Eliashberg spectral function $\alpha^2 F(\omega)\geq 0$ that is $\propto\omega^2$ for small $\omega>

Using the recent reformulation for the Eliashberg theory of superconductivity in terms of a classical interacting Bloch spin chain model, rigorous upper and lower bounds on the critical temperature $T_c$ are obtained for the $\gamma$ model -- a versi

We establish fundamental upper bounds on the electron-phonon interaction strength and superconducting transition temperature $T_c$ in metals stemming from an intrinsic instability of the equilibrium between electrons and the crystal lattice with resp

Probing Large Language Models for Scalar Adjective Lexical Semantics and Scalar Diversity Pragmatics
Scalar adjectives pertain to various domain scales and vary in intensity within each scale (e.g. certain is more intense than likely on the likelihood scale). Scalar implicatures arise from the consideration of alternative statements which could have

We discuss the dependence of the critical properties of the Anderson model on the dimension $d$ in the language of $\beta$-function and renormalization group recently introduced in Ref.[arXiv:2306.14965] in the context of Anderson transition on rando

It has been recently reported that irregular objects sink irregularly when released in a granular medium: a subtle lack of symmetry in the density or shape of a macroscopic object may produce a large tilting and deviation from the vertical path when

In one dimension density-density interactions of particles reduce their mobility and hence the Drude weight, which controls the divergence of the optical conductivity at zero frequency, decreases. We study effects of pair hopping events on this resul
