Metal-Insulator and Magnetic Phase Diagram of Ca$_2$RuO$_4$ from Auxiliary Field Quantum Monte Carlo and Dynamical Mean Field Theory

Layered perovskite ruthenium oxides exhibit a striking series of metal-insulator and magnetic-nonmagnetic phase transitions easily tuned by temperature, pressure, epitaxy, and nonlinear drive. Expand abstract.

Six-loop $\varepsilon$ expansion study of three-dimensional $O(n)\times O(m)$ spin models

The Landau-Wilson field theory with $O(n)\times O(m)$ symmetry which describes the critical thermodynamics of frustrated spin systems with noncollinear and noncoplanar ordering is analyzed in $4 - \varepsilon$ dimensions within the minimal subtraction scheme in the six-loop approximation.

Gravitational Waves from Phase Transition in Minimal SUSY $U(1)_{B-L}$ Model

Many extensions of the Standard Model include a new $U(1)$ gauge group that is broken spontaneously at a scale much above TeV. Expand abstract.

Confinement/deconfinement phase transition and dual Meissner effect in SU(3) Yang-Mills theory

Finally, we measure the associated magnetic--monopole current induced around the chromo-flux tube and observe that the confinement/deconfinement phase transition is associated with the appearance/disappearance of the induced magnetic--monopole current, respectively. Expand abstract.

Optically Driven Magnetic Phase Transition of Monolayer RuCl3

Analysis shows that this magnetic phase transition is driven by a combined effect of doping-induced lattice strain and itinerant ferromagnetism. Expand abstract.

Role of spin mixing conductance in determining thermal spin pumping near the ferromagnetic phase transition in EuO_{1-x} and La2NiMnO6

Additionally, the T-dependence of the real part of Gmix derived from spin Hall magnetoresistance measurements at different temperatures for the Pt/LNMO structure, further establish the interdependence. Expand abstract.

Relativistic hybrid stars with sequential first-order phase transitions and heavy-baryon envelopes

Fermion-induced quantum critical point in Dirac semimetals: a sign-problem-free quantum Monte Carlo study

According to Landau criterion, a phase transition should be first order when cubic terms of order parameters are allowed in its effective Ginzburg-Landau free energy. Expand abstract.
