Topological properties of QCD with two dynamical fermions [PDF]

open access: yes, 1999
We investigate the topological susceptibility of the QCD vacuum with two flavours of dynamical staggered fermions on the lattice both at zero and finite temperature.

Neutral-plasma oscillations at zero temperature

open access: yesPhysical Review E, 2003
We use cold plasma theory to calculate the response of an ultracold neutral plasma to an applied rf field. The free oscillation of the system has a continuous spectrum and an associated damped quasimode. We show that this quasimode dominates the driven response. We use this model to simulate plasma oscillations in an expanding ultracold neutral plasma,

Regional temperature extremes and vulnerability under net zero CO2 emissions

open access: yesEnvironmental Research Letters, 2023
Signatories to the Paris Agreement have pledged to keep global warming to well below 2 °C above pre-industrial levels and preferably below 1.5 °C above pre-industrial levels.

Glassy dynamics near zero temperature

open access: yes, 2000
We numerically study finite-dimensional spin glasses at low and zero temperature, finding evidences for (i) strong time/space heterogeneities, (ii) spontaneous time scale separation and (iii) power law distributions of flipping times.

Energy loss at zero temperature from extremal black holes

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Using the AdS/CFT correspondence, we probe the extremal black holes by studying the energy loss of a moving heavy point particle in a strongly-coupled boundary field theory at zero temperature and finite charge density. We first consider the extremal AdS-

Open XXZ chain and boundary modes at zero temperature

open access: yesSciPost Physics, 2019
We study the open XXZ spin chain in the anti-ferromagnetic regime and for generic longitudinal magnetic fields at the two boundaries. We discuss the ground state via the Bethe ansatz and we show that, for a chain of even length L and in a regime where

Holographic Superconductor/Insulator Transition at Zero Temperature [PDF]

open access: yes, 2010
We analyze the five-dimensional AdS gravity coupled to a gauge field and a charged scalar field. Under a Scherk-Schwarz compactification, we show that the system undergoes a superconductor/insulator transition at zero temperature in 2+1 dimensions as we ...

Analytic critical points of charged Rényi entropies from hyperbolic black holes

open access: yesJournal of High Energy Physics, 2021
We analytically study phase transitions of holographic charged Rényi entropies in two gravitational systems dual to the N $$ \mathcal{N} $$ = 4 super-Yang-Mills theory at finite density and zero temperature.

Quasi-isotropic fiber metal laminate with high specific modulus and near-zero coefficient of thermal expansion

open access: yesInternational Journal of Lightweight Materials and Manufacture, 2021
On the basis of lamination theory, a quasi-isotropic fiber metal laminate (FML) with a near-zero coefficient of thermal expansion (CTE) and high specific modulus was designed, using pitch-based carbon fiber reinforced plastic (CFRP) prepreg and stainless
