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.

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.

Demonstration of a quantized acoustic octupole topological insulator

Furthermore, we reveal topological phase transitions from higher- to lower-order multipole moments in altered designs of acoustic TIs. 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.

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.

Quasi-periodic dynamical phase transitions in multi-band topological insulators and connections with entanglement entropy and fidelity susceptibility

Finally we investigate the dynamics of the entanglement entropy generated after a quench, and its potential relation to dynamical phase transitions. Expand abstract.

Continuous quantum phase transition in the fermionic mass solutions of the Nambu-Jona-Lasinio model

Recently quantum simulators have been constructed to investigate experimentally the most prominent theoretical four-point many-body system described by the Hubbard model. Expand abstract.
