Evidence for topological defects in a photoinduced phase transition [PDF]
Nature Physics, 2018 Upon excitation with an intense laser pulse, a symmetry-broken ground state can undergo a non-equilibrium phase transition through pathways different from those in thermal equilibrium.

Quantum phase transitions [PDF]
Philosophical Magazine B, 2001 We give a general introduction to quantum phase transitions in strongly-correlated electron systems. These transitions which occur at zero temperature when a non-thermal parameter $g$ like pressure, chemical composition or magnetic field is tuned to a critical value are characterized by a dynamic exponent $z$ related to the energy and length scales $ $

Electric Field Induced Collapse of Charge-Ordered Phase in Manganites [PDF]
, 2006 The colossal electroresistance in manganites is a concomitant of the electric field induced insulator-to-metal phase transition. A phenomenological phase transition model is proposed to study this electric field induced collapse of charge-ordered phase ...

Electroweak phase transition and baryogenesis in composite Higgs models [PDF]
Journal of High Energy Physics, 2018 We present a comprehensive study of the electroweak phase transition in composite Higgs models, where the Higgs arises from a new, strongly-coupled sector which confines near the TeV scale. This work extends our study in ref. [1].

Phase transitions in phylogeny [PDF]
Transactions of the American Mathematical Society, 2003 We apply the theory of markov random fields on trees to derive a phase transition in the number of samples needed in order to reconstruct phylogenies. We consider the Cavender-Farris-Neyman model of evolution on trees, where all the inner nodes have degree at least 3, and the net transition on each edge is bounded by e.

Revised structural phase diagram of (Ba0.7Ca0.3TiO3)-(BaZr0.2Ti0.8O3) [PDF]
, 2013 The temperature-composition phase diagram of barium calcium titanate zirconate (x(Ba0.7Ca0.3TiO3)(1-x)(BaZr0.2Ti0.8O3); BCTZ) has been reinvestigated using high-resolution synchrotron x-ray powder diffraction.

Evidence for a strain-tuned topological phase transition in ZrTe5 [PDF]
Science Advances, 2018 In situ strain is used to induce a topological phase transition in single-crystal ZrTe5. A phase transition between topologically distinct insulating phases involves closing and reopening the bandgap.

Cosmic phase transitions [PDF]
Annalen der Physik, 2000 AbstractThe sequence of phase transitions during the hot history of the universe is followed within a phenomenological framework. Particular emphasis is put on the QCD confinement transition, which is at reach under earth laboratory conditions. A tepid inflationary scenario on the GUT scale with bubble growth at moderate supercooling is discussed.

Order of superconductive phase transition
Condensed Matter Physics, 2005 On the occasion of Reinhard Folk's 60th birthday, I give a brief review of the theoretical progress in understanding the critical properties of superconductors. I point out the theoretical difficulties in finding a second-order transition in the Ginzburg-
