Formation of random singlets in the nanocrystalline quasi-one-dimensional spin-1/2 antiferromagnet Sr21Bi8Cu2(CO3)2O41

Autor: Guo, Yanbo, Hu, Xinzhe, Siddiquee, Hasan, Kumarasinghe, Kapila, Yadav, Swapnil M., Choi, Eun Sang, Nakajima, Yasuyuki, Takano, Yasumasa

Induced by quenched disorder, random-singlet states occur in a variety of low-dimensional spin-1/2 antiferromagnets, some of them candidates for quantum spin liquids. Here we report measurements of the specific heat, magnetization, and magnetic susce

Fermi surfaces of the topological semimetal CaSn$_{3}$ probed through de Haas van Alphen oscillations

Autor: Siddiquee, K A M Hasan, Munir, Riffat, Dissanayake, Charuni, Hu, Xinzhe, Yadav, Swapnil, Takano, Yasumasa, Choi, Eun Sang, Le, Duy, Rahman, Talat S, Nakajima, Yasuyuki

In the search of topological superconductors, nailing down the Fermiology of the normal state is as crucial a prerequisite as unraveling the superconducting pairing symmetry. In particular, the number of time-reversal-invariant momenta in the Brillou

On the computation of density and two-point correlation functions of a class of random matrix ensembles

Autor: Alam, Kazi, Yadav, Swapnil, Muttalib, K. A.

We demonstrate a method to solve a general class of random matrix ensembles numerically. The method is suitable for solving log-gas models with biorthogonal type two-body interactions and arbitrary potentials. We reproduce standard results for a vari

Nonmonotonic confining potential and eigenvalue density transition for generalized random matrix model

Autor: Yadav, Swapnil, Alam, Kazi, Muttalib, K. A., Wang, Dong

Publikováno v: Phys. Rev. E 103, 042137 (2021)

We consider several limiting cases of the joint probability distribution for a random matrix ensemble with an additional interaction term controlled by an exponent $\gamma$ (called the $\gamma$-ensembles). The effective potential, which is essentiall

Generalized random matrix model with additional interactions

Autor: Yadav, Swapnil, Alam, Kazi, Muttalib, K. A., Wang, Dong

Publikováno v: Journal of Physics. A. Mathematical and Theoretical 53 (2020), 15001, (15pages)

We introduce a log-gas model that is a generalization of a random matrix ensemble with an additional interaction, whose strength depends on a parameter $\gamma$. The equilibrium density is computed by numerically solving the Riemann-Hilbert problem a

Finite field regime for a quantum spin liquid in $\alpha$-RuCl$_3$

Autor: Balz, Christian, Lampen-Kelley, Paula, Banerjee, Arnab, Yan, Jiaqiang, Lu, Zhilun, Hu, Xinzhe, Yadav, Swapnil M., Takano, Yasu, Liu, Yaohua, Tennant, D. Alan, Lumsden, Mark D., Mandrus, David, Nagler, Stephen E.

Publikováno v: Phys. Rev. B 100, 060405 (2019)

An external magnetic field can induce a transition in $\alpha$-RuCl$_3$ from an ordered zigzag state to a disordered state that is possibly related to the Kitaev quantum spin liquid. Here we present new field dependent inelastic neutron scattering an
