, 2014 This work is concerned with thermal quantum states of Hamiltonians on spin and fermionic lattice systems with short range interactions. We provide results leading to a local definition of temperature, thereby extending the notion of "intensivity of ...

BCS-BEC Crossover Effects and Pseudogap in Neutron Matter
Universe, 2020 Due to the large neutron–neutron scattering length, dilute neutron matter resembles the unitary Fermi gas, which lies half-way in the crossover from the BCS phase of weakly coupled Cooper pairs to the Bose–Einstein condensate of dimers.

Energy transfer between colloids via critical interactions [PDF]
, 2017 We report the observation of a temperature-controlled synchronization of two Brownian-particles in a binary mixture close to the critical point of the demixing transition.

Occupancy‐derived thermal affinities reflect known physiological thermal limits of marine species
Ecology and Evolution, 2020 Predicting how species will respond to increased environmental temperatures is key to understanding the ecological consequences of global change. The physiological tolerances of a species define its thermal limits, while its thermal affinity is a summary

Superconductors with two critical temperatures [PDF]
Physica C: Superconductivity and its Applications, 2007 We propose a simple model for superconductors endowed with two critical temperatures, corresponding to two second-order phase transitions, in the framework of the Ginzburg-Landau mean-field theory. For very large Cooper pair self-interaction, in addition to the standard condensation occurring in the Ginzburg-Landau theory, we find another phase ...

Predictive Modeling of Critical Temperatures in Superconducting Materials
Molecules, 2020 In this study, we have investigated quantitative relationships between critical temperatures of superconductive inorganic materials and the basic physicochemical attributes of these materials (also called quantitative structure-property relationships ...

The Influence of Preparation Temperature on the Different Facets of Bulk MgB2 Superconductors
Micromachines, 2023 Two MgB2 samples were prepared using the spark plasma sintering (SPS) technique at different temperatures—950 °C (S1) and 975 °C (S2)—for 2 h under 50 MPa pressure to study the influence of preparation temperature on different facets, namely those ...
