Reversible phase transition in 8,19-dimethyl-2,3,8,19-tetraazapentacyclo[13.7.0.04,12.06,10.017,21]docosa-1(15),2,4(12),5,10,16,21-heptaene-7,9,18,20-tetrone

open access: yesActa Crystallographica Section E: Crystallographic Communications
The crystal structure of the title compound, C20H14N4O4, was previously reported at 220 K [Businski et al. (2025). Chem. Eur. J. A71, 3–8], where it crystallizes in the monoclinic space group P21/c with one crystallographically independent molecule in a ...

Quark-Hadron Phase Transitions in Viscous Early Universe [PDF]

open access: yes, 2012
Based on hot big bang theory, the cosmological matter is conjectured to undergo QCD phase transition(s) to hadrons, when the universe was about $1-10 \mu$s old.

Phase transitions in the diagonal ensemble of two-band Chern insulators

open access: yesNew Journal of Physics, 2016
We identify a new class of phase transitions when calculating the Hall conductance of two-band Chern insulators in the long-time limit after a global quench of the Hamiltonian.

Magnetoresistance Features at the Magnetic Field-Induced Phase Transition in FeRh Thin Films

open access: yesJournal of Mathematical and Fundamental Sciences, 2023
The causes of the appearance of first-order magnetic phase transitions remain a mystery. FeRh alloy is a classical material where a first-order magnetic phase transition occurs.

Instability of many-body localized systems as a phase transition in a nonstandard thermodynamic limit

open access: yes, 2019
The many-body localization (MBL) phase transition is not a conventional thermodynamic phase transition. Thus to define the phase transition one should allow the possibility of taking the limit of an infinite system in a way that is not the conventional ...

Phase Transition to Exact Susy [PDF]

open access: yes, 2007
The anthropic principle is based on the observation that, within narrow bounds, the laws of physics are such as to have allowed the evolution of life. The string theoretic approach to understanding this observation is based on the expectation that the ...

Experimental Signals of Phase Transition

open access: yes, 2003
The connection between the thermodynamics of charged finite nuclear systems and the asymptotically measured partitions is presented. Some open questions, concerning in particular equilibrium partitions are discussed.

Relativistic hydrodynamics with phase transition

open access: yesEuropean Physical Journal C: Particles and Fields
Assessing the applicability of hydrodynamic expansions close to phase transition points is crucial from either theoretical or phenomenological points of view.

Experimental validation of phase space conduits of transition between potential wells

open access: yes, 2018
A phase space boundary between transition and non-transition, similar to those observed in chemical reaction dynamics, is shown experimentally in a macroscopic system.

Correlation between electric-field-induced phase transition and piezoelectricity in lead zirconate titanate films [PDF]

open access: yes, 2014
We observed that electric field induces phase transition from tetragonal to rhombohedral in polycrystalline morphotropic lead zirconate titanate (PZT) films, as reported in 2011 for bulk PZT.
