Quantized heat flow in moiré chern bands of bilayer graphene
Santanu Samai, Debangan Sarkar, Abhijit Halder +5
When electrons are subjected simultaneously to a magnetic field and a periodic potential, they form the fractal Hofstadter spectrum, whose topological gaps host quantum Hall and Ch…
Dipolar interlayer excitons in transition metal dichalcogenide alloy heterobilayers
E. Katsipoulaki, N. G. Chatzarakis, E. Rigoutsou +6
Interlayer excitons in transition metal dichalcogenide (TMD) heterobilayers possess a permanent electric dipole moment and long recombination lifetimes, making them a promising pla…
Second-Order Synaptic Memory using Inherent Plasticity of Moiré Superlattices
Tanweer Ahmed, Kenji Watanabe, Takashi Taniguchi +2
Achieving synaptic functionality electronically in a single-element quantum material is a fundamental challenge, as conventional methods rely on the introduction of extrinsic charg…
Gate-Tunable Photoresponse of Graphene Josephson Junctions at Terahertz Frequencies
X. Zhou, I. Gayduchenko, A. Kudriashov +12
Graphene Josephson junctions (JJ) provide a promising platform for ultra-broadband quantum sensing of light owing to graphene's frequency-independent absorption, vanishing electron…
Programmable, Spontaneous Superlattice Memory in a Monolayer Topological Insulator
Jian Tang, Thomas Siyuan Ding, Shuhan Ding +24
Memory is a foundational concept across disciplines, from neurobiology and electronics to artificial intelligence and quantum gravity. In materials, memory effects typically arise…
Trion transfer in mixed-dimensional heterostructures
N. Fang, U. Erkilic, Y. R. Chang +10
Charged excitons, or trions, offering unique spin and charge degrees of freedom, have primarily been investigated in doped systems where charges are long considered indispensable.…
