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.

Ergodic theory of affine isometric actions on Hilbert spaces

The classical Gaussian functor associates to every orthogonal representation of a locally compact group $G$ a probability measure preserving action of $G$ called a Gaussian action. 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.

Topological excitations in rotating Bose-Einstein condensates with Rashba-Dresselhaus spin-orbit coupling in a two-dimensional optical lattice

For the initially immiscible BECs with fixed 2D RD-SOC strength, the increase of rotation frequency can result in the structural phase transition from square vortex lattice to irregular triangular vortex lattice and the system transition from initial phase separation to phase mixing.

Drastic suppression of superconducting $T_{c}$ by anisotropic strain near a nematic quantum critical point

High temperature superconductivity emerges in the vicinity of competing strongly correlated phases. Expand abstract.

Phase transitions for degenerate random environments

We study a class of models of i.i.d.~random environments in general dimensions $d\ge 2$, where each site is equipped randomly with an environment, and a parameter $p$ governs the frequency of certain environments that can act as a barrier. Expand abstract.

Quasiperiodic dynamical quantum phase transitions in multiband topological insulators and connections with entanglement entropy and fidelity susceptibility

Finally, we investigate the fidelity susceptibility as an indicator of the topological phase transitions, and find a simple scaling law as a function of the number of bands of our multiband model which is found to be the same for both bulk and boundary fidelity susceptibilities. Expand abstract.
