Ferromagnetism Mechanism in a Geometrically Frustrated Triangular Lattice

Kavli Affiliate: Zheng Zhu | First 5 Authors: Qianqian Chen, Shuai A. Chen, Zheng Zhu, , | Summary: We study the emergent itinerant ferromagnetism and propose its underlying mechanism in the geometrically frustrated triangular lattice. Based on large-scale density matrix renormalization group simulations and unrestricted Hartree-Fock mean-field analysis, we identify itinerant ferromagnetic phases in the […]

Correlators of $mathcal{N}=4$ SYM on real projective space at strong coupling

Kavli Affiliate: Xinan Zhou | First 5 Authors: Xinan Zhou, , , , | Summary: We consider type IIB supergravity on a $mathbb{Z}_2$ quotient of AdS$_5times$S$^5$ as the holographic dual of strongly coupled 4d $mathcal{N}=4$ SYM on $mathbb{RP}^4$ space with the gauging of charge conjugation. Using bootstrap techniques, we determine all two-point functions of $frac{1}{2}$-BPS […]

Dynamical scaling behavior of the two-dimensional random singlet state in the random $Q$ model

Kavli Affiliate: Long Zhang | First 5 Authors: Chen Peng, Long Zhang, , , | Summary: In this work, we study the scaling relation of energy and length scales in the 2D random-singlet (RS) state of the random $Q$ model. To investigate the intrinsic energy scale of the spinon subsystem arising from the model, we […]

Universal Quench Dynamics of an Open Quantum System

Kavli Affiliate: Long Zhang | First 5 Authors: Chengxiang Ding, Long Zhang, , , | Summary: Taking the quantum Kitaev chain as an example, we have studied the universal dynamical behaviors resulting from quantum criticality under the condition of environmental temperature quench. Our findings reveal that when the quantum parameter is at its critical value, […]

Magnetocaloric Effect of Topological Excitations in Kitaev Magnets

Kavli Affiliate: Gang Su | First 5 Authors: Han Li, Enze Lv, Ning Xi, Yuan Gao, Yang Qi | Summary: Traditional magnetic sub-Kelvin cooling relies on the nearly free local moments in hydrate paramagnetic salts, whose utility is hampered by the dilute magnetic ions and low thermal conductivity. Here we propose to use instead fractional […]

Spectroscopic Feature of Quantum Many-Body Scar States

Kavli Affiliate: Long Zhang | First 5 Authors: Wenjie Wei, Long Zhang, , , | Summary: We study the dynamical correlations of nonintegrable systems with quantum many-body scar (QMBS) states generated by a ladder operator. The spectral function of the ladder operator has an exact $delta$-function peak induced by the QMBS states. As a concrete […]

Emergent quantum disordered phase in Na$_2$Co$_2$TeO$_6$ under intermediate magnetic field along $c$ axis

Kavli Affiliate: Gang Su | First 5 Authors: Xu-Guang Zhou, Han Li, Chaebin Kim, Akira Matsuo, Kavita Mehlawat | Summary: Identifying the exotic quantum spin liquid phase in Kitaev magnets has garnered great research interests and remains a significant challenge. In experiments, most of the proposed candidate materials exhibit an antiferromagnetic (AFM) order at low […]

Shocking and Mass Loss of Compact Donor Stars in Type Ia Supernovae

Kavli Affiliate: Lars Bildsten | First 5 Authors: Tin Long Sunny Wong, Christopher White, Lars Bildsten, , | Summary: Type Ia supernovae arise from thermonuclear explosions of white dwarfs accreting from a binary companion. Following the explosion, the surviving donor star leaves at roughly its orbital velocity. The discovery of the runaway helium subdwarf star […]
