Variational non-gaussian approach to interacting spin-boson models
João Pedro Mendonça, Yao Wang, Krzysztof Jachymski
We apply a hybrid variational framework to interacting spin-boson Hamiltonians, targeting regimes where simulations are limited by the unbounded bosonic Hilbert space and strong ma…
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…
Light Control of Triplet Pairing in Correlated Electrons with Mixed-Sign Interactions
Zecheng Shen, Chendi Xie, Wei-Chih Chen +1
Spin-triplet superconductivity is a key platform for topological quantum computing, yet its experimental realization and control in solid-state materials remain a significant chall…
A light-induced charge order mode in a metastable cuprate ladder
Hari Padma, Prakash Sharma, Sophia F. R. TenHuisen +17
We report the observation of an emergent charge order mode in the optically-excited cuprate ladder SrCuO. Near-infrared light in the ladder plane drives a symm…
Role of Matter Interactions in Superradiant Phenomena
João Pedro Mendonça, Krzysztof Jachymski, Yao Wang
The superradiant phenomenon, usually described by the Dicke model, is a hallmark of strong light-matter interaction. We explore how matter-matter interactions influence this phenom…
Symmetry-protected electronic metastability in an optically driven cuprate ladder
Hari Padma, Filippo Glerean, Sophia F. R. TenHuisen +23
Optically excited quantum materials exhibit nonequilibrium states with remarkable emergent properties, but these phenomena are usually transient, decaying on picosecond timescales…
