Topological Quantum Phase Transition and Superconductivity Induced by Pressure in the Bismuth Tellurohalide BiTeI [PDF]

Advances in Materials, 2016
A pressure‐induced topological quantum phase transition has been theoretically predicted for the semiconductor bismuth tellurohalide BiTeI with giant Rashba spin splitting.

Strain induced structural phase transition and compositional dependent magnetic phase transition in Ti doped Bi0.80Ba0.20FeO3 ceramics

Heliyon, 2022
Bi0.80Ba0.20Fe1-xTixO3 (0≤x≤0.10) samples are prepared using solid state reaction technique. Bi3+ site is replaced with 20 % Ba2+ which induced structural modification from rhombohedral to pseudo cubic accompanied by the creation of oxygen vacancies ...

Homogeneous nucleation near a second phase transition and Ostwald's step rule

, 2001
Homogeneous nucleation of the new phase of one transition near a second phase transition is considered. The system has two phase transitions, we study the nucleation of the new phase of one of these transitions under conditions such that we are near or ...

Chiral phase transition in lattice QCD as a metal-insulator transition [PDF]

, 2006
We investigate the lattice QCD Dirac operator with staggered fermions at temperatures around the chiral phase transition. We present evidence of a metal-insulator transition in the low lying modes of the Dirac operator around the same temperature as the ...

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.

Observation of a Dissipative Phase Transition in a One-Dimensional Circuit QED Lattice [PDF]

Physical Review X, 2016
Nonequilibrium phase transitions, where the physical properties of a system change suddenly, are of fundamental importance in condensed matter physics but are not well understood.

Orbital Selective Phase Transition

, 2013
We review theoretical investigations on the origin of the orbital selective phase where localized and itinerant electrons coexist in the d shell at intermediate strength of the on-site Coulomb interactions between electrons.

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_ ...

Reversible phase transition in 8,19-dimethyl-2,3,8,19-tetraazapentacyclo[13.7.0.04,12.06,10.017,21]docosa-1(15),2,4(12),5,10,16,21-heptaene-7,9,18,20-tetrone

Acta Crystallographica Section E: Crystallographic Communications
The crystal structure of the title compound, C20H14N4O4, was previously reported at 220 K [Businski et al. (2025). Chem. Eur. J. A71, 3–8], where it crystallizes in the monoclinic space group P21/c with one crystallographically independent molecule in a ...
