Accelerating universes driven by bulk particles [PDF]

open access: yesPhysical Review D, 2005
We consider our universe as a 3d domain wall embedded in a 5d dimensional Minkowski space-time. We address the problem of inflation and late time acceleration driven by bulk particles colliding with the 3d domain wall. The expansion of our universe is mainly related to these bulk particles.

Bulk induced phase transition in driven diffusive systems [PDF]

open access: yesScientific Reports, 2014
This Letter studies a weakly and asymmetrically coupled three-lane driven diffusive system. A non-monotonically changing density profile in the middle lane has been observed. When the extreme value of the density profile reaches $ρ=0.5$, a bulk induced phase transition occurs which exhibits a shock and a continuously and smoothly decreasing density ...

Giant bulk photovoltaic effect driven by the wall-to-wall charge shift in WS2 nanotubes

open access: yesNature Communications, 2022
We demonstrate that double-wall or multi-wall WS2 nanotubes can exhibit unexpectedly efficient bulk photovoltaic effect owing to its unique inter-wall charge-shifting excitations.

Intermixing‐Driven Surface and Bulk Ferromagnetism in the Quantum Anomalous Hall Candidate MnBi6Te10

open access: yesAdvanced Science, 2023
The recent realizations of the quantum anomalous Hall effect (QAHE) in MnBi2Te4 and MnBi4Te7 benchmark the (MnBi2Te4)(Bi2Te3)n family as a promising hotbed for further QAHE improvements. The family owes its potential to its ferromagnetically (FM) ordered

Glioblastoma cell fate is differentially regulated by the microenvironments of the tumor bulk and infiltrative margin

open access: yesCell Reports, 2023
Summary: Glioblastoma (GBM) recurrence originates from invasive margin cells that escape surgical debulking, but to what extent these cells resemble their bulk counterparts remains unclear.
