Tracking topological defect motion and incommensurate charge order melting in a perovskite manganite

Posted by klaurent Cornell

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Noah Schnitzer, Berit H. Goodge, Gregory Powers, Jaewook Kim, Sang-Wook Cheong | Summary: Charge order pervades the phase diagrams of many quantum materials where it competes with superconducting and magnetic phases, hosts electronic phase transitions and topological defects, and couples to the lattice generating intricate structural […]

Quasicrystalline Spin Liquid

Posted by Cornell

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Sunghoon Kim, Mohammad Saad, Dan Mao, Adhip Agarwala, Debanjan Chowdhury | Summary: The interplay of electronic interactions and frustration in crystalline systems leads to a panoply of correlated phases, including exotic Mott insulators with non-trivial patterns of entanglement. Disorder introduces additional quantum interference effects that can drive […]

Flux-tunable Kitaev chain in a quantum dot array

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Juan Daniel Torres Luna, A. Mert Bozkurt, Michael Wimmer, Chun-Xiao Liu, | Summary: Connecting quantum dots through Andreev bound states in a semiconductor-superconductor hybrid provides a platform to create a Kitaev chain. Interestingly, in a double quantum dot, a pair of poor man’s Majorana zero modes can […]

Quantum Melting of a Disordered Wigner Solid

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Ziyu Xiang, Hongyuan Li, Jianghan Xiao, Mit H. Naik, Zhehao Ge | Summary: The behavior of two-dimensional electron gas (2DEG) in extreme coupling limits are reasonably well-understood, but our understanding of intermediate region remains limited. Strongly interacting electrons crystalize into a solid phase known as the Wigner […]
