, 2009 In this paper, we present an exactly solvable phase transition model in which the phase transition is purely statistically derived. The phase transition in this model is a generalized Bose-Einstein condensation.

The weak electroweak phase transition [PDF]
, 1993 We present a detailed analysis of the phase transition in the standard model at finite temperature. Using an improved perturbation theory, where plasma masses are determined from a set of one-loop gap equations, we evaluate the effective potential $V_ ...

Quantum Phase Transition and Universal Dynamics in the Rabi Model. [PDF]
Physical Review Letters, 2015 We consider the Rabi Hamiltonian, which exhibits a quantum phase transition (QPT) despite consisting only of a single-mode cavity field and a two-level atom. We prove QPT by deriving an exact solution in the limit where the atomic transition frequency in

The Saccharomyces cerevisiae amino acid transporter Lyp1 has a broad substrate spectrum
FEBS Letters, EarlyView.In Saccharomyces cerevisiae, Yeast Amino acid Transporter family members mediate the import of amino acids, ranging from substrate specialists to generalists. Here, we show that the specialist transporter, Lyp1, has a broader substrate spectrum than previously described, with affinity constants spanning from micromolar to millimolar.

Thermoelectric converters of electrical and optical signals — new class of thermoelectric devices [PDF]
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2008 The new class of thermoelectric devices for converting signals is based on thermoelectric controlling of element parameters with phase transition in a narrow temperature-field of phase transition.

Baryogenesis at a lepton-number-breaking phase transition
Journal of High Energy Physics, 2017 We study a scenario in which the baryon asymmetry of the universe arises from a cosmological phase transition where lepton-number is spontaneously broken.

Deconfinement transitions in a generalised XY model [PDF]
J. Phys. A: Math. Theor. 50 (2017) 424003, 2017 We find the complete phase diagram of a generalised XY model that includes half-vortices. The model possesses superfluid, pair-superfluid and disordered phases, separated by Kosterlitz-Thouless (KT) transitions for both the half-vortices and ordinary vortices, as well as an Ising-type transition.

, 2015 We study topological properties of phase transition points of two topologically non-trivial $\mathbb{Z}_2$ classes (D and DIII) in one dimension by assigning a Berry phase defined on closed circles around the gap closing points in the parameter space of ...

Phase transition in quantum gravity [PDF]
, 1999 A fundamental problem with attempting to quantize general relativity is its perturbative non-renormalizability. However, this fact does not rule out the possibility that non-perturbative effects can be computed, at least in some approximation. We outline

Probing the Electroweak Phase Transition with Higgs Factories and Gravitational Waves [PDF]
, 2016 After the discovery of the Higgs boson, understanding the nature of electroweak symmetry breaking and the associated electroweak phase transition has become the most pressing question in particle physics.
