Disentangling multi-spin dynamic correlations in the Heisenberg spin- chain
V. K . Bhartiya, U. Kumar, T. Kim +8
Higher-order correlations are essential for understanding exotic phases and uncovering universal aspects of quantum dynamics. While inelastic neutron scattering provides well-estab…
Excitations across the equilibrium and photoinduced `hidden' states of magnetoresistive manganites
Shiyu Fan, Feng Jin, Taehun Kim +16
"Hidden" phases, generated using ultrafast laser pulses (few hundred femtoseconds), with properties distinct from thermodynamic equilibrium, are appealing for technologies because…
Spin dynamics and 1/3 magnetization plateau in a coupled distorted diamond chain compound K2Cu3(MoO4)4
G. Senthil Murugan, J. Khatua, Suyoung Kim +11
We investigate magnetic properties of the = 1/2 compound KCu(MoO) by combining magnetic susceptibility, magnetization, specific heat, and electron spin…
Floquet engineering of Kitaev quantum magnets
Umesh Kumar, Saikat Banerjee, Shi-Zeng Lin
In recent years, there has been an intense search for materials realizing the Kitaev quantum spin liquid model. A number of edge-shared compounds with strong spin-orbit coupling, s…
Inverse Faraday effect in Mott insulators
Saikat Banerjee, Umesh Kumar, Shi-Zeng Lin
The inverse Faraday effect (IFE), where a static magnetization is induced by circularly polarized light, offers a promising route to ultrafast control of spin states. Here we study…
Spontaneous fractional Chern insulators in transition metal dichalcogenides Moire superlattices
Heqiu Li, Umesh Kumar, Kai Sun +1
Moir{é} superlattice realized in two-dimensional heterostructures offers an exciting platform to access strongly-correlated electronic states. In this work, we study transition met…
