Lattice distortions, moiré phonons, and relaxed electronic band structures in magic-angle twisted bilayer graphene
Bo Xie and Jianpeng Liu
Author(s): Bo Xie and Jianpeng Liu

In this paper, we present a theoretical research on the lattice relaxations, phonon properties, and relaxed electronic structures in magic-angle twisted bilayer graphene (TBG). We construct a continuum elastic model in order to study the lattice dynamics of magic-angle TBG, where both in-plane and o…

Triclinic ${\mathrm{BiFeO}}_{3}$: A room-temperature multiferroic phase with enhanced magnetism and resistivity
Md. Sariful Sheikh, Tushar Kanti Bhowmik, Alo Dutta, Sujoy Saha, Chhatra R. Joshi, and T. P. Sinha
Author(s): Md. Sariful Sheikh, Tushar Kanti Bhowmik, Alo Dutta, Sujoy Saha, Chhatra R. Joshi, and T. P. Sinha

The magnetic and transport properties of ${\mathrm{BiFeO}}_{3}/{\mathrm{La}}_{2}{\mathrm{NiMnO}}_{6}$ (BFO/LNMO) composite were investigated both experimentally and theoretically. Unlike the normal rhombohedral $(R3c)$ phase, BFO in composites is crystallized in the triclinic phase $(P1)$. Interesti…

Dirac fermions on wires confined to the graphene Möbius strip
L. N. Monteiro, C. A. S. Almeida, and J. E. G. Silva
Author(s): L. N. Monteiro, C. A. S. Almeida, and J. E. G. Silva

We investigate the effects of the curved geometry on a massless relativistic electron constrained to a graphene strip with a Möbius strip shape. The anisotropic and parity violating geometry of the Möbius band produces a geometric potential that inherits these features. By considering wires along th…

Probing angle-dependent thermal conductivity in twisted bilayer $\mathrm{Mo}{\mathrm{Se}}_{2}$
Manab Mandal, Nikhilesh Maity, Prahalad Kanti Barman, Ashutosh Srivastava, Abhishek K. Singh, Pramoda K. Nayak, and Kanikrishnan Sethupathi
Author(s): Manab Mandal, Nikhilesh Maity, Prahalad Kanti Barman, Ashutosh Srivastava, Abhishek K. Singh, Pramoda K. Nayak, and Kanikrishnan Sethupathi

Twisted bilayer (t-BL) transition-metal dichalcogenides (TMDCs) have attracted considerable attention in recent years due to their distinctive electronic properties, which arise due to the moiré superlattices that lead to the emergence of flat bands and correlated electron phenomena. Also, these mat…

Flow of higher Berry curvature and bulk-boundary correspondence in parametrized quantum systems
Xueda Wen, Marvin Qi, Agnès Beaudry, Juan Moreno, Markus J. Pflaum, Daniel Spiegel, Ashvin Vishwanath, and Michael Hermele
Author(s): Xueda Wen, Marvin Qi, Agnès Beaudry, Juan Moreno, Markus J. Pflaum, Daniel Spiegel, Ashvin Vishwanath, and Michael Hermele

This paper is concerned with the physics of parametrized gapped quantum many-body systems, which can be viewed as a generalization of conventional topological phases of matter. In such systems, rather than considering a single Hamiltonian, one considers a family of Hamiltonians that depend continuou…

Field orientation dependent magnetic phases in the Weyl semimetal ${\mathrm{Co}}_{3}{\mathrm{Sn}}_{2}{\mathrm{S}}_{2}$
Samuel E. Pate, Bin Wang, Bing Shen, J. Samuel Jiang, Ulrich Welp, Wai-Kwong Kwok, Jing Xu, Kezhen Li, Ralu Divan, and Zhi-Li Xiao
Author(s): Samuel E. Pate, Bin Wang, Bing Shen, J. Samuel Jiang, Ulrich Welp, Wai-Kwong Kwok, Jing Xu, Kezhen Li, Ralu Divan, and Zhi-Li Xiao

Magnetism plays a key role in the emergence of topological phenomena in the Weyl semimetal ${\mathrm{Co}}_{3}{\mathrm{Sn}}_{2}{\mathrm{S}}_{2}$, which exhibits ferromagnetic interactions along the $c$-axis of the crystal and antiferromagnetic (AFM) interactions within the $ab$ plane. Extensive studi…

Thermal conductivity of monolayer graphene: Convergent and lower than diamond
Zherui Han and Xiulin Ruan
Author(s): Zherui Han and Xiulin Ruan

The thermal conductivity of monolayer graphene is widely believed to surpass that of diamond even for few-micron-size samples and was proposed to diverge with system size. Here, we predict the thermal conductivity from first principles by considering four-phonon scattering, phonon renormalization, a…

Viscous friction acting on a solid disk falling in confined fluid: Lessons for the scaling analysis
Nana Tanaka and Ko Okumura
Author(s): Nana Tanaka and Ko Okumura

A fundamental law relevant at small scales such as in cells and microchannels is found to be universally expressed as a single straight line on a plot with nontrivial reason. The established simple law is potentially useful for various kinds of small-scale physics and provides lessons useful for various fields across science, giving a widely applicable example for explaining apparent scaling laws, which cannot be understood by simple dimensional analysis.

Ideal Chern bands as Landau levels in curved space
Benoit Estienne, Nicolas Regnault, and Valentin Crépel
Author(s): Benoit Estienne, Nicolas Regnault, and Valentin Crépel

What are some propitious conditions for the emergence of chiral topological phases in the absence of an external field? Identifying all solid-state bands that can be exactly mapped to a Landau level (with a spatially varying metric and magnetic field) provides the bedrock for exact fractional Chern insulating ground states.
