On the Douglas-Kazakov phase transition

open access: yesESAIM: Proceedings and Surveys, 2015
We give a rigorous proof of the fact that a phase transition discovered by Douglas and Kazakov in 1993 in the context of two-dimensional gauge theories occurs. This phase transition can be formulated in terms of the Brownian bridge on

Gravitational waves from a first-order electroweak phase transition: a brief review [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017
We review the production of gravitational waves by an electroweak first-order phase transition. The resulting signal is a good candidate for detection at next-generation gravitational wave detectors, such as LISA.

The phase transitions between $Z_n\times Z_n$ bosonic topological phases in 1+1 D, and a constraint on the central charge for the critical points between bosonic symmetry protected topological phases [PDF]

open access: yesNuclear Physics, B 919 (2017), pp. 470-503, 2017
The study of continuous phase transitions triggered by spontaneous symmetry breaking has brought revolutionary ideas to physics. Recently, through the discovery of symmetry protected topological phases, it is realized that continuous quantum phase transition can also occur between states with the same symmetry but different topology.

Doping-induced structural phase transition in cobalt diselenide enables enhanced hydrogen evolution catalysis

open access: yesNature Communications, 2018
Transition metal dichalcogenide materials have been explored extensively as catalysts to negotiate the hydrogen evolution reaction, but they often run at a large excess thermodynamic cost.

More on Phase Structure of Nonlocal 2D Generalized Yang-Mills Theories (nlgYM$_2$'s) [PDF]

open access: yes, 2002
We study the phase structure of nonlocal two dimensional generalized Yang - Mills theories (nlgYM$_2$) and it is shown that all order of $\phi^{2k}$ model of these theories has phase transition only on compact manifold with $g = 0$(on sphere), and the ...
