A High-pressure Investigation of the Synthetic Analogue of Chalcomenite, CuSeO3∙2H2O

This conclusion is supported by Raman spectroscopy studies which have detected the phase transition at 4.5(2) GPa and by the first-principles computing simulations. Expand abstract.

Quantum Phase Transitions of the Distorted Diamond Spin Chain

It is found that this model exhibits three quantum phases; the ferrimagnetic phase, the spin gap one, and the gapless Tomonaga-Luttinger liquid depending on the exchange coupling parameters. Expand abstract.

Shear Banding, Intermittency, Jamming and Dynamic Phases for Skyrmions in Inhomogeneous Pinning Arrays

As the drive increases further, the flow becomes disordered and the skyrmion Hall angle increases with drive until saturating at the highest drives when the system transitions into a moving crystal phase. Expand abstract.

Bandwidth-tuning from insulating Mott quantum spin liquid to Fermi liquid via chemical substitution in $\kappa$-[(BEDT-TTF)$_{1-x}$(BEDT-STF)$_x$]$_2$Cu$_2$(CN)$_3$

At this first-order phase transition, metallic regions coexist in the insulating matrix leading to pronounced percolative effects most obvious in a strong enhancement of the dielectric constant at low temperatures. Expand abstract.

Strong First Order Electroweak Phase Transition in Gauge-Higgs Unification at Finite Temperature

We analyze the electroweak phase transition at finite temperature in a model of gauge-Higgs unification where the fermion mass hierarchy including top quark mass, a viable electroweak symmetry breaking and an observed Higgs mass are successfully reproduced. Expand abstract.

Partial-Symmetry-Breaking Phase Transitions

We demonstrate a novel feature of certain phase transitions in theories with large rank symmetry group that exhibit specific types of non-local interactions. Expand abstract.

Axisymmetric flows on the torus geometry

We find a second order phase transition in the equilibrium location of the stripe as a function of area, and this phase transition leads to a complex dependence of the Laplace pressure on the stripe area. Expand abstract.

0-1 phase transitions in sparse spiked matrix estimation

For Bernoulli and Bernoulli-Rademacher distributed vectors, and when the sparsity and signal strength satisfy an appropriate scaling relation, these formulas imply sharp 0-1 phase transitions for the asymptotic minimum mean-square-error. Expand abstract.

Magnetic glassy state at low spin state of Co3+ in EuBaCo2O5+{\delta} ({\delta} = 0.47) cobaltite

The present results will open a new window to search the microscopic relation between the spin state transitions and the kinetic arrest induced magnetic glassy phenomena in complex materials. Expand abstract.
