Electromagnetic signatures of chiral quantum spin liquid
Saikat Banerjee, Wei Zhu, Shi-Zeng Lin
Quantum spin liquid (QSL) has become an exciting topic in interacting spin systems that do not order magnetically down to the lowest experimentally accessible temperature; however,…
Mesoscopic critical fluctuations
Saikat Banerjee, Nikolai A. Sinitsyn
We investigate magnetic fluctuations of a mesoscopic critical region at the interface induced by smooth time-independent spacial changes of a control parameter across its critical…
New static solutions of symmetric equation
Avinash Khare, Saikat Banerjee, Avadh Saxena
In this paper, we provide new exact solutions of nonlinear Klein-Gordon () equation in -dimension. For simplicity, we focus on the static equation and ignore the time-dep…
Superposed periodic kink and pulse solutions of coupled nonlinear equations
Avinash Khare, Saikat Banerjee, Avadh Saxena
We present novel previously unexplored periodic solutions, expressed in terms of Jacobi elliptic functions, for both a coupled model and a coupled nonlinear Schrödinger equat…
Emergent orbital magnetization in Kitaev quantum magnets
Saikat Banerjee, Shi-Zeng Lin
Unambiguous identification of the Kitaev quantum spin liquid (QSL) in materials remains a huge challenge despite many encouraging signs from various measurements. To facilitate the…
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…
Higher Chern numbers in multilayer () Lieb lattices: Topological transitions and quadratic band crossing lines
Saikat Banerjee, Avadh Saxena
We consider a hitherto unexplored setting of stacked multilayer () Lieb lattice which undergoes an unusual topological transition in the presence of intra-layer spin-o…
Intrinsic Hallmarks of Phonon-Induced Charge Order in Cuprates
S. Banerjee, W. A. Atkinson, A. P. Kampf
Charge-density wave (CDW) modulations in underdoped high-temperature cuprate superconductors remain a central puzzle in condensed matter physics. However, despite a substantial exp…
Bose-Einstein condensate of Dirac magnons: Pumping and collective modes
P. O. Sukhachov, S. Banerjee, A. V. Balatsky
We explore the formation and collective modes of Bose-Einstein condensate of Dirac magnons (Dirac BEC). While we focus on two-dimensional Dirac magnons, an employed approach is gen…
Dirac magnons in honeycomb ferromagnets
Sergey S. Pershoguba, Saikat Banerjee, J. C. Lashley +4
The discovery of the Dirac electron dispersion in graphene led to the question of the Dirac cone stability with respect to interactions. Coulomb interactions between electrons were…
Granular Superconductor in a honeycomb lattice as a realization of Bosonic Dirac Material
Saikat Banerjee, J. Fransson, A. M. Black-Schaffer +2
We examine the low energy effective theory of phase oscillations in a two-dimensional granular superconducting sheet where the grains are arranged in honeycomb lattice structure. U…
Landau-like states in neutral particles
Saikat Banerjee, Hans Ågren, Alexander V. Balatsky
We show the emergence of a new type of dispersion relation for neutral atoms with an interesting similarity with the spectrum of 2-dimensional electrons in an applied perpendicular…
