Global Organization of Three-Dimensional, Volume-Preserving Flows: Constraints, Degenerate Points, and Lagrangian Structure

Bharath Ravu, Guy Metcalfe, Murray Rudman +2

Global organization of 3-dimensional (3D) Lagrangian chaotic transport is difficult to infer without extensive computation. For 3D time-periodic flows with one invariant we show ho…

Near-direct bandgap / type-II pn heterojunction for enhanced ultrafast photodetection and high-performance photovoltaics

Abin Varghese, Dipankar Saha, Kartikey Thakar +5

PN heterojunctions comprising layered van der Waals (vdW) semiconductors have been used to demonstrate current rectifiers, photodetectors, and photovoltaic devices. However, a dire…

Wet and dry internal friction can be measured with the Jarzynski equality

R. Kailasham, Rajarshi Chakrabarti, J. Ravi Prakash

The existence of two types of internal friction wet and dry is revisited, and a simple protocol is proposed for distinguishing between the two types and extracting the appropriate…

Universality of the collapse transition of sticky polymers

Aritra Santra, Kiran Kumari, R. Padinhateeri +2

The universality of the swelling of the radius of gyration of a homopolymer relative to its value in the state, independent of polymer-solvent chemistry, in the crossover regim…
