Development of the concept of absolute zero temperature
Educación Química, 2018 La posibilidad de un cero absoluto de la temperatura fue introducida en una etapa temprana del desarrollo científico. La existencia del Primum Firgidum, un cuerpo supremamente frío, fue objeto de mucha discussion entre filósofos y científicos hasta el ...

Mechanism of temperature-induced zero drift on electro-hydraulic servo valve
AIP Advances, 2021 An electro-hydraulic servo valve is objectively asymmetrical in the process of fabrication and assembly, and the zero position is the result of comprehensive adjustment.

Rigidity transitions in zero-temperature polygons
Physical Review E, 2022 We study geometrical clues of a rigidity transition due to the emergence of a system-spanning state of self stress in under-constrained systems of individual polygons and spring networks constructed from such polygons. When a polygon with harmonic bond edges and an area spring constraint is subject to an expansive strain, we observe that convexity of ...

Neutral-plasma oscillations at zero temperature
Physical 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
Environmental 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.

Energy loss at zero temperature from extremal black holes
European 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
SciPost 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

Zero temperature limit of holographic superconductors [PDF]
Journal of High Energy Physics, 2009 We consider holographic superconductors whose bulk description consists of gravity minimally coupled to a Maxwell field and charged scalar field with general potential. We give an analytic argument that there is no "hard gap": the real part of the conductivity at low frequency remains nonzero (although typically exponentially small) even at zero ...

Analytic critical points of charged Rényi entropies from hyperbolic black holes
Journal 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.
