The four-fold rotational symmetry breaking in the hidden order phase, which imposes a strong constraint on the theoretical model, is observed through the magnetic torque measurement. The translationally invariant phase with broken rotational symmetry is interpreted as meaning that the hidden-order phase is an electronic “nematic” phase. The observation of such nematicity in URu\u003csub\u003e2\u003c\/sub\u003eSi\u003csub\u003e2\u003c\/sub\u003e indicates a ubiquitous nature among the strongly correlated electron systems.\u003c\/p\u003e\u003cp\u003eThe author also studies the superconducting state of URu\u003csub\u003e2\u003c\/sub\u003eSi\u003csub\u003e2\u003c\/sub\u003e below\u003ci\u003e T\u003c\/i\u003e\u003csub\u003ec \u003c\/sub\u003e= 1.4 K, which coexists with the hidden-order phase. A peculiar vortex penetration in the superconducting state is found, which may be related to the rotational symmetry breaking in the hidden-order phase. The author also identifies a vortex lattice melting transition. This transport study provides essential clues to the underlying issue of quasiparticle dynamics as to whether a quasiparticle Bloch state is realized in the periodic vortex lattice.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Springer Japan","offers":[{"title":"Default Title","offer_id":47053049004272,"sku":"9784431545910","price":129.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9784431545910_p0.jpg?v=1763713364","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9784431545910","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
