Topological States of Matter [PDF]

, 2012
My research program is focused on the study of elastic deformation and topological defects in two materials: graphene and topological insulators. In both systems at low energies the electrons have a nearly linear spectrum, i.e. they behave like relativistic fermions.

Topological states of matter in low dimensions

, 2018
A central theme in condensed matter physics is the classification and characterization of states of matter. In the recent decades, it has become evident that there exists a large class of quantum mechanical systems that must be classified according to properties deeply rooted in the mathematical field of topology, rather than in terms of which ...

Journal of High Energy Physics, 2022
We develop a mathematical theory of separable higher categories based on Gaiotto and Johnson-Freyd’s work on condensation completion. Based on this theory, we prove some fundamental results on E m -multi-fusion higher categories and their higher centers.

Non-local order parameters and quantum entanglement for fermionic topological field theories

Journal of High Energy Physics, 2020
We study quantized non-local order parameters, constructed by using partial time-reversal and partial reflection, for fermionic topological phases of matter in one spatial dimension protected by an orientation reversing symmetry, using topological ...

Quantum mechanism of extremely high energy processes at neutron star collapse and of quasar luminosity

Journal of High Energy Physics, 2022
Using the braid group topological approach to quantum statistics we demonstrate that for strong gravitational field occurring in neutron star merger with mass exceeding the Tolman, Oppenheimer and Volkoff limit the quantum statistics of particles beneath

Defects in the 3-dimensional toric code model form a braided fusion 2-category

Journal of High Energy Physics, 2020
It was well known that there are e-particles and m-strings in the 3-dimensional (spatial dimension) toric code model, which realizes the 3-dimensional ℤ2 topological order.

Crystallographic interacting topological phases and equivariant cohomology: to assume or not to assume

Journal of High Energy Physics, 2021
For symmorphic crystalline interacting gapped systems we derive a classification under adiabatic evolution. This classification is complete for non-degenerate ground states.

Principles of topology in understanding and development of topological states of matter [PDF]

Iranian Journal of Physics Research, 2020
در دهه‌های اخیر فیزیکدانان مادة چگال با به‌‌کار بردن مفاهیم توپولوژی توسعه داده شده در ریاضی و مکانیک کوانتومی و درک ارتباط عمیق آنها، حالت‌های جدیدی از مواد را کشف کرده و الگوهایی برای طبقه‌بندی فازهای مواد ارائه داده‌اند. این موضوع حتی دانش شیمی مربوط به اوربیتال‌ها و پیوندهای اتمی و همچنین علم توسعة مواد با خواص مورد انتظار را دگرگون کرده است.
