Altermagnetism and bond-nematicity in the spin- square lattice model
Tanja Đurić, Shenlong Yu, Pinaki Sengupta
We study appearance of bond-nematicity in insulating altermagnetic materials induced by increased frustration and quantum-fluctuations driven melting of the altermagnetic order. Us…
Quantum fluctuations and strong mass renormalization in NiCl2-4SC(NH2)2
Y. Kohama, A. Sologubenko, N. R. Dilley +9
In a number of quantum paramagnets, magnetic field can induce a quantum phase transition to an antiferromagnetic state which exists for a range of fields Hc1 < H < Hc2. Generally,…
Magnetoelectric effects in an organo-metallic quantum magnet
V. S. Zapf, F. Nasreen, F. Wolff-Fabris +1
We observe a bilinear magnetic field-induced electric polarization of 50 in single crystals of NiCl-4SC(NH) (DTN). DTN forms a tetragonal structure that breaks…
Topological Confinement and Superconductivity
K. A. Al-Hassanieh, C. D. Batista, P. Sengupta +1
We derive a Kondo Lattice model with a correlated conduction band from a two-band Hubbard Hamiltonian. This mapping allows us to describe the emergence of a robust pairing mechanis…
Geometric Frustration and Dimensional Reduction at a Quantum Critical Point
C. D. Batista, J. Schmalian, N. Kawashima +5
We show that the spatial dimensionality of the quantum critical point associated with Bose--Einstein condensation at T=0 is reduced when the underlying lattice comprises a set of l…
