Entanglement Energetics at Zero Temperature

open access: yes, 2003
We show how many-body ground state entanglement information may be extracted from sub-system energy measurements at zero temperature. Generically, the larger the measured energy fluctuations are, the larger the entanglement is.

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

Temperature induced phase transitions in four fermion models in curved space-time [PDF]

open access: yes, 1998
The large N limit of the Gross-Neveu model is here studied on manifolds with constant curvature, at zero and finite temperature. Using the zeta-function regularization, the phase structure is investigated for arbitrary values of the coupling constant ...

Zero-temperature localization in a sub-Ohmic spin-boson model investigated by an extended hierarchy equation of motion

open access: yes, 2017
With a decomposition scheme for the bath correlation function, the hierarchy equation of motion (HEOM) is extended to the zero-temperature sub-Ohmic spin-boson model, providing a numerically accurate prediction of quantum dynamics. As a dynamic approach,

Zero Temperature Limit of Holographic Superconductors

open access: yes, 2009
We consider holographic superconductors whose bulk description consists of gravity minimally coupled to a Maxwell field and charged scalar field with general potential.

Decoherence at zero temperature [PDF]

open access: yes, 2002
Most discussions of decoherence in the literature consider the high-temperature regime but it is also known that, in the presence of dissipation, decoherence can occur even at zero temperature.

Metastability of the Ising model on random regular graphs at zero temperature [PDF]

open access: yes, 2014
We study the metastability of the ferromagnetic Ising model on a random r-regular graph in the zero temperature limit. We prove that in the presence of a small positive external field the time that it takes to go from the all minus state to the all plus ...

Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment

open access: yesFEBS Letters, EarlyView.
The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

open access: yesFEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.
