DOI: 10.1007/jhep10(2021)193
Abstract: Abstract We show how the generation of right-handed neutrino masses in Majoron models may be associated with a first-order phase transition and accompanied by the production of a stochastic background of gravitational waves (GWs). We… read more here.

DOI: 10.1016/j.jmmm.2017.08.052
Abstract: Abstract Magnetic nature of Gd 3 Co is investigated using detailed measurements of temperature and field dependent magnetization. The antiferromagnetic phase is field-instable due to prevailing ferromagnetic exchange correlations above Neel temperature T N ∼… read more here.

DOI: 10.1021/acs.macromol.0c02593
Abstract: When a cylinder forming triblock copolymer thin film is exposed to supercritical carbon dioxide (scCO2), the system suffers an order–order phase transition from parallel (C∥) to perpendicularly ori... read more here.

DOI: 10.1089/ast.2016.1481
Abstract: Abstract It is well known that life on Earth alters its environment over evolutionary and geological timescales. An important open question is whether this is a result of evolutionary optimization or a universal feature of… read more here.

DOI: 10.1103/physrevb.102.205110
Abstract: We report the discovery of a first-order phase transition at around 125 K in NbCrP, which is a nonsymmorphic crystal with the $Pnma$ space group. From the resistivity, magnetic susceptibility, and nuclear magnetic resonance measurements… read more here.

Fermion-enhanced first-order phase transition and chiral Gross-Neveu tricritical point

DOI: 10.1103/physrevb.103.075147
Abstract: The fluctuations of massless Dirac fermion can not only turn a first-order bosonic phase transition (in the Landau sense) to a quantum critical point, but also work reversely to enhance the first-order transition itself, depending… read more here.

DOI: 10.1103/physrevb.98.045123
Abstract: We report an asymmetry in the R vs T characteristics across the first order metalinsulator transition (MIT) of V2O3 nanowires. The resistance changes in a few, large jumps during cooling through the MIT, while it… read more here.

Abstract: We investigate the thermodynamic phase behaviour of rotating and slowly accelerating AdS black holes. While we find some similarities with the non-rotating charged counterparts, such as the peculiar phenomena of "snapping swallow tails" we also… read more here.

Abstract: The massive two-dimensional Nambu--Jona-Lasinio model with isospin (isoNJL) is reconsidered in the large $N_c$ limit. We continue the exploration of its phase diagram by constructing missing first-order phase boundaries. At zero temperature, a phase boundary… read more here.

Abstract: We propose a novel dark matter (DM) scenario based on a first-order phase transition in the early universe. If dark fermions acquire a huge mass gap between true and false vacua, they can barely penetrate… read more here.

Abstract: Making use of both the stochastic approach to the tunneling phenomenon and the threshold statistics, we offer a simple argument to show that critical bubbles may be correlated in first-order phase transitions and biased compared… read more here.
